The report provides an independent\, in-depth review of Australia’s CCUS industry\, outlining its necessity\, key success factors for project execution\, and the status and outlook of CCUS (including CCS) projects in the country. The technical analysis identifies five essential factors for a successful CCUS project\, emphasising its crucial role in achieving the 2050 net-zero greenhouse gas emissions target. However\, at the current rate of development\, carbon capture and storage will fall short of meeting both global and Australian targets on time. Huw Mason will present an overview of the report’s findings and discuss the outlook for Australian projects.

SUMMARY:2025 PESA WEBINAR SERIES: Mega-Intrusions and Volcanic Ruins: A Tour of Magmatism in the Carnarvon Basin
DESCRIPTION:Kindly supported by Rock Flow dynamics  \n  \nThis live webinar will take place at: \n11am | Perth\n12.30pm | Darwin\n1pm | Brisbane\n1:30pm | Adelaide\n2pm | Canberra\, Hobart\, Melbourne\, Sydney \nUse the calendar link on this page to add this event in to your own calendar at the correct local time for your location. \nTickets are free for members (please log in to see this) and $10 for non members. \nPlease buy your tickets and immediately follow the link in the ticket e-mail (not the calendar invite or this webpage\, which is just generic and not event specific) to set up your registration with the webinar software well in advance of the time of the talk.

Magma was emplaced into the Exmouth Plateau and Exmouth Sub-Basin over an area of ~50\,000 km2. Until recently the spatial distribution of this igneous system\, and hence its potential impact on regional petroleum systems\, was relatively unknown. The only references to the magmatic system were 1990s ‘blob’ maps created using 100+ km spaced 2D seismic\, magnetic and gravity data\, and references of penetrations of igneous rocks in well completion reports from ~8 wells and boreholes. \nNew interpretive work (the essence of my PhD)\, utilising SLB & TGS ultra-broadband 3D seismic data covering much of the Exmouth Plateau and Exmouth Subbasin\, reveals the igneous system in all its glory! In this talk we will tour both its intrusive and extrusive components\, asking why it is the way it is and what its current configuration might have meant for the development of Carnarvon Basin petroleum systems. We will attempt to answer why some intrusions are of record-breaking proportions (170+ km long)\, while others nearby are much much smaller (3 to 5 km diameter). We’ll also look at the eroded ruins of volcanoes (that until recently hadn’t been known to exist at all) and consider the original size of the volcanic complex\, and the implications of volcano erosion on regional reservoir quality.

SUMMARY:2025 PESA WEBINAR SERIES: Tracking the Fate of CO2 from Switzerland to Iceland with Geophysical Methods
DESCRIPTION:Kindly supported by Rock Flow dynamics  \n  \nThis live webinar will take place at: \nPLEASE NOTE TIME CHANGE FOR THIS EVENT: \n1pm | Perth\n2.30pm | Darwin\n3pm | Brisbane\n3:30pm | Adelaide\n4pm | Canberra\, Hobart\, Melbourne\, Sydney \nUse the calendar link on this page to add this event in to your own calendar at the correct local time for your location. \nTickets are free for members (please log in to see this) and $10 for non members. \nPlease buy your tickets and immediately follow the link in the ticket e-mail (not the calendar invite or this webpage\, which is just generic and not event specific) to set up your registration with the webinar software well in advance of the time of the talk.

Geophysical techniques can help characterise and monitor the storage reservoir. Seismic time lapse\, electrical resistivity tomography (ERT) and gravity measurements are often used to track the CO2 plume. In the few existing in-situ mineral storage sites\, monitoring relies almost only on geochemical methods.Geophysical methods are less established in this context. Seismic time lapse measurements are thought to be less efficient because the CO2 is dissolved in water before it is pumped in\, so the local water is replaced by the CO2-enriched water\, which makes the seismic velocity changes too small to detect.Carbonate precipitation happens slowly and makes very small velocity changes\, mainly because the porosity decreases. ERT involves replacing the existing groundwater with CO2-charged water. This should lead to a decrease in resistivity. However\, resistivity is only expected to increase when carbonates precipitate. Here\, we present the results of testing geophysical methods to measure and check the CO2 storage site in Helguvik\, Iceland\, operated by CARBFIX. This study is part of the Swiss DemoUpCARMA project (https://demoupcarma.ethz.ch/) and uses a variety of scientific methods that have already been successfully tested in other CO2 storage experiments (e.g. Zappone et al.\, 2021). The Helgivik site is a pilot were CARBFIX is testing the efficiency to use sea water for dissolving CO2\, in preparation for an upscaling of the site\, the Coda Terminal that will receive and store 3 million tons of CO2 per year. \nThe pilot storage site lies on the Reykjanes Peninsula in Southwest Iceland\, at about 15 km distance from the seismically and volcanically active rift zone. The CO2 is captured in Switzerland are shipped in isotainers (https://demoupcarma.ethz.ch/) to Helguvik . Here\, after mixing with saline water\, it is injected into the reservoir through a vertical borehole (CBI-01; Fig. 1) with an open section between 250 m and 420 m depth. Two additional vertical wells\, CBM-03 and CBM-01\, with depths of approximately 400 metres\, have been drilled at distances of 30 metres and 100 metres along a northwest-southeast alignment\, respectively\, for the purpose of monitoring reservoir processes. Rock samples obtained from drill cuttings have been utilised in the characterisation of the stratigraphic sequence of the reservoir\, in conjunction with borehole logging data. Furthermore\, drill cores extracted from proximate boreholes have undergone laboratory analysis with respect to porosity network and flow properties\, both prior to and following il laboratory exposure to CO2-rich saline water. Prior to and during the injection operations\, cross-hole seismic measurements were conducted utilising a P-wave borehole sparker source and hydrophone chains. Simultaneously\, single-hole electrical resistivity measurements were performed in all the wells. The background seismicity and the seismicity potentially induced by the injection operations were monitored via a backbone seismic network installed around the injection site\, and by a seismic array of 3D nodal geophones. The data were streamed in real time to ETH Zurich and shared with all the project partners. \nThe multi-disciplinary approach reveals variability of the porosity in the basaltic layers\, already evidenced by laboratory measurements (Stavropoulou et al\, 2024)\, depicting a stratified velocity distribution with depth Single-hole electrical resistivity data corroborate the layering and is in agreement with the mineralogical data from cuttings. The remarkable consistency between ERT and crosshole seismic observations (Junker at al.\, 2025 ) highlights the efficiency of the methods to resolve thin layering structures and giving additional constraints to the borehole logging observations for permeable layers. Characterization with geophysical tools allows the continuity of the underground structures to be observed\, in contrast to point borehole measurements. A permeability model\, based on the crosshole seismic data is found to be in agreement with borehole spinner tests. Modeling on velocity anomalies due to precipitation of Carbonates reveal that that crosshole seismic can detect the precipitation of c.a. 17 kg/m3\, corresponding to c.a. 100 t of injected CO2 at the scale of the pilot project. \nAcknowledgements: This study is part of the DemoUpStorage project that was funded by the Swiss Federal Office of Energy (SFOE\, project number SI/502429).

SUMMARY:2025 PESA WEBINAR SERIES: Cretaceous – Paleogene Evolution of Bottom Currents in the Northern Carnarvon Basin\, Northwest Shelf of Australia

In this study\, we provide a detailed characterisation of Aptian to Rupelian deposits that developed in the centre of the Exmouth Plateau of the Northern Carnarvon Basin\, Northwest Shelf of Australia\, on c. 500 km wide ramp-type margin\, characterised by gentle slope breaks between the coastline and the deep basin. Sediment mounds and moats initially developed during the Aptian to Turonian in clastic sediments in the southwest of the study area\, whereas reduced sediment accumulation characterised the north-eastern sector. During the Turonian to Lutetian\, a transition to carbonate sedimentation occurred. Interestingly\, these features continued to develop\, with the mounds gradually establishing themselves through aggradational growth\, while the moats were infilled by sediments exhibiting complex structures\, including small-scale mounds and incisions with a wide variety of different morphologies. From the Danian to Rupelian\, there was a notable decrease in moat infilling and mound growth\, leading to significant progradation of sediment toward the northeast. This final stage of sedimentation was characterised by stacked deep incisions\, ridges\, and conical depressions. Initial stages of deposition correspond to a period of time when a wide and open ocean was present to the north of Australia\, but only narrow seaways and intracontinental rifts\, associated with the breakup of Gondwana\, were present to the west and south. The accelerated growth of mounds occurred during a period of accelerated separation of Greater Indian and Australia while cessation of bottom current activity corresponds to a period of rapid separation of Australia from Antarctica. The recognition and investigation of bottom current features provide new insights into the way in which oceanic circulation patterns may have evolved as the breakup of Gondwana progressed and can help our understanding of the processes that operate during the early stages of passive margin development and the formation of oceanic basins. In addition\, more detailed knowledge of the sedimentary deposits that comprise the post-rift sequence in the Northen Carnarvon Basin can help improve understanding of velocity variations and drilling conditions in these sequences.

SUMMARY:2025 PESA WEBINAR SERIES: Where Comes the Gas From\, Where Does it Go? Southern Denison Trough CO2 Storage Possibilities from a Geological Perspective
DESCRIPTION:Kindly supported by Rock Flow dynamics  \n  \nThis live webinar will take place at: \n11am              – Perth\n12.30pm       – Darwin\, Adelaide\n1pm                – Brisbane\, Canberra\, Hobart\, Melbourne\, Sydney \nUse the calendar link on this page to add this event in to your own calendar at the correct local time for your location. \nTickets are free for members (please log in to see this) and $10 for non members. \nPlease buy your tickets and immediately follow the link in the ticket e-mail (not the calendar invite or this webpage\, which is just generic and not event specific) to set up your registration with the webinar software well in advance of the time of the talk. Once registered with the webinar software you will receive a reminder e-mail 1 hour beforehand. \nWhere Comes the Gas From\, Where Does it Go?  Southern Denison Trough CO2 Storage Possibilities from a Geological Perspective \nPresented by Alison Troup (University of Queensland) \nAbstract \n\nThe southern Denison Trough contains several depleted conventional gas fields\, mostly reservoired in the Aldebaran Sandstone with secondary reservoirs in sandstones of the upper Reids Dome beds. These gas fields are naturally high in CO2 and may present a good opportunity from a geological perspective for CO2 storage. In support of this an updated interpretation of the depositional environment at Merivale\, Westgrove\, Yellowbank and Punchbowl Gully has been developed to examine changes in depositional environment along the Aldebaran Sandstone paleocoastline. Comparison of the production history of Merivale to the variability in the depositional environment shows that there is strong contribution from the depositional environment to production behaviour. \nSandstones and coal seams in the upper Reids Dome beds may present a secondary target to depleted gas field storage in the southern Denison Trough. Gas distribution in the Reids Dome beds coals shows that the Hutton-Wallumbillla Fault may be a migration pathway for magmatic CO2 into the unit. High CO2 concentrations and saturations within these coals demonstrate a natural analogue for storage within this system. The stratigraphic placement of these coal seams has been improved through the use of stable carbon isotope analysis.

(Navigating gas water rock reactions and potential groundwater impacts)\nPresented by Dr Julie Pearce (University of Queensland) \nAbstract \n\nCarbon dioxide geological storage is one option to enable Australia to reach net zero. Several carbon storage demonstration sites are undergoing feasibility studies and environmental impact assessment internationally and in Australia. Very recently CO2 storage in the Surat Basin gained a lot of media and political attention – the QLD government has now put a ban on CCS in the geographical extent of the QLD Great Artesian Basin (and below it). The reservoir that was being assessed is in a deep (~2300 m)\, brackish\, unpotable part of the Precipice Sandstone. However\, the broader formation is an aquifer of the GAB\, therefore stakeholders were sensitive to potential environmental impacts. The previous demonstration site that underwent assessment was further north in the shallower part of the Precipice Sandstone (~1200 m). In that Glenhaven site the West Wandoan 1 well was drilled for the feasibility study\, and the reservoir had fresh groundwater. This presentation details part of the experimental and field sampling components of the underlying research\, including CO2-water-rock geochemical reactions\, metal mobilisation\, and creation of a reactive transport model. \n

Since the 1980’s these outcrops have been central to the development of sequence stratigraphic and provide unparalleled insight into large scale geometries and architectures in shallow marine and coastal plain reservoirs such as the Brent Group\, the Niger Delta and the Jurassic clastic deposits of the Caernarvon Basin. \nRecent advances in digital outcrop acquisition techniques\, including the use of drones to acquire photogrammetric 3D models has revolutionised reservoir analogue studies. In this presentation a dataset which includes over 100 km of virtual outcrop data will be used to provide a fully integrated Virtual Fieldtrip and highlight the use of this technology to provide quantitative analogue data\, illustrate correlation strategies\, provide input for reservoir models and illustrate links between modern and ancient systems. We will also discuss recent analysis of the perception of virtual field trips and demonstrate their pros and cons with respect to different audiences.

Despite this\, global inflationary pressures continued to fall during the year\, although they remained higher than pre-pandemic levels. In Australia\, activism around climate change issues continued to impact project developments and sentiment in the industry remained somewhat subdued. The PESA 2024 Development and Production Review looks back at the oil and gas development and production activities in Australia in 2024 and tries to provide some sense of what happened\, and what that means for the industry looking forward. Liquefied natural gas (LNG) production in Australia recorded (unexpectedly) a new record high\, although several projects are now facing declining production. Santos won a significant court case in January 2024 on the Barossa project\, enabling it to resume construction activity on the main export pipeline to Darwin\, which had been suspended for approximately 2 months. The east coast domestic market continued to have major concerns about gas supply and one of the three gas plants at Longford was shutdown reducing supply and processing capacity significantly. Gas supply remains a critical issue in the Northern Territory.

Burial diagenesis\, in particular\, refers to the diagenetic modifications occurred due to the influence of burial processes in the mesogenetic environment. The study of diagenesis is important in both siliciclastic and carbonate reservoirs; however\, they are key in the latter since they are more chemically reactive. The Perla Limestone\, an Oligo-Miocene carbonate reservoir located in the Gulf of Venezuela Basin\, considered the largest gas field in Latin America (>17 Tscf of gas in place)\, shows a complex porosity system marked by a strong diagenetic control. Despite comprehensive depositional facies modelling carried out in this reservoir\, inconsistencies remained when distributing petrophysical properties with depositional facies. Specifically\, in areas strongly affected by diagenetic processes since they constitute a complex variable to reproduce in a predictive reservoir quality-model. In order to understand the impact of diagenesis in the Perla Limestone\, and its distribution along the carbonate succession; a detailed petrographic\, mineralogical and chemical analysis on well-cores was performed. As a result\, several diagenetic processes that created and destroyed porosity and permeability were identified and grouped chronologically in function of the evolution of the diagenetic environment. Within these processes\, an important burial dissolution process\, likely linked to the ascent of CO2-rich fluids mediated by basement-root faults\, fractures\, and stylolites allowed the development of pervasive secondary porosity in the vicinity of the major discontinuity surfaces. On the other hand\, blocky-calcite cementation in the near surface to shallow burial environment\, and the progressive mechanical compaction in the burial realm\, were the main responsible for reservoir quality destruction.

Evidence of these phenomena primarily manifest on seismic data as fluid pipes/gas chimneys and pockmarks on surfaces. This presentation will review research completed on this topic and demonstrate how studying these occurrences can provide insight into subsurface fluid dynamics and contribute to better assessing petroleum systems elements.

Onshore jurisdictions dominate the exploration and appraisal activities. In total 82 exploration and appraisal wells were drilled in 2024 (spud date after 31 December 2023). Sixty of these were appraisal wells\, and this was dominated by coal seam gas appraisal drilling in Queensland. Despite the release of the Australian Government’s Future Gas Strategy\, there does not appear to be much in the way of tangible actions to increase exploration. All jurisdictions make land available for exploration via competitive tender\, but in 2024 there were no land releases. Seismic activity in offshore jurisdictions is being limited with new Commonwealth awards being granted without the right to acquire new seismic. Carbon sequestration (CCS) activity continued offshore with the grant of eight of the 2023 land release areas occurring in 2024. While Western Australia\, South Australia and the Northern Territory are taking steps to create the framework for CCS exploration\, in Queensland a sudden announcement saw the cessation of all CCS activity in the Great Artesian Basin\, and importantly also the underlying strata. This ban applies to the use of CO2 in enhanced oil recovery as well. South Australia continues to take lead in natural hydrogen exploration.

This paper however provides invaluable insights into the high-resolution depositional modelling of the Kingia Sandstone using sedimentary facies analysis integrated with detailed ichnological studies. Historic cored wells have also been re-evaluated utilising an ichnological approach\, while newly released cored wells have been interpreted\, also using this integrated approach. Cores from a variety of wells including but not limited to West Erreguella-4\, South Erreguella-1\, Mountain Bridge-1\, Corybas-1\, Waitsia-1\, Waitsia-2 and Waitsia-3 have been included in this study. \nThe results allow the subdivision of the Kinga Sandstone into numerous sub-environments reflecting marginal to fully marine  sub-environments. The Kinga sandstone is interpreted to represent deposition in a wave-dominated deltaic system\, with trace-fossil assemblages key to the evaluation of stress levels (e.g. freshwater dilution) in the system. Local sharp-based shoreface packages\, abruptly overlying shelfal deposits\, are interpreted to represent forced regressive events during overall highstand progradation of the Kingia shoreface system.

At the time of the project several work-over opportunities existed in the field\, with Kenmore-43\, a previously cased and suspended but yet to be completed well\, identified as one of the best candidates to potentially improve field production. Focusing on the Jurassic Basal Birkhead and Hutton intervals\, a geological model was built to capture a range of possible static outcomes\, test each case dynamically and once matched\, forecast the potential production if Kenmore-43 were to be perforated. The modelling work was closely integrated with the simulation results and was continuously refined to obtain the best possible history match. In all cases that achieved a match\, Kenmore-43 was identified as a viable economic opportunity which followed through with a very successful workover. The project highlighted the value of integrated static and dynamic modelling and how this not only improves understanding of the field but also has wider implications for other opportunities both within Kenmore and analogous fields in the basin.

By systematically digitising legacy and modern cuttings through automated washing\, high-resolution imaging\, and advanced segmentation algorithms\, Grain-e extracts quantitative data traditionally captured only through qualitative wellsite descriptions. \nUsing a variety of AI workflows to identify and measure individual grains\, providing unbiased statistical analysis of grain size\, sorting\, sphericity\, and roundness across 1\,000-5000 particles per sample. This eliminates interpreter bias and delivers data-driven insights including subtle trends no technology has picked up previously. \nKey applications span the well lifecycle: \nGeological Insights: Optical stratigraphy using digital colour analysis reveals high-resolution correlations beyond simple sand/shale distinctions\, identifying subtle depositional changes stacking patterns\, with additional insights from enhancing colour spectra or investigating trace colour occurrences. \nReservoir Characterisation: Particle size distributions optimise completion design or inform sedimentological interpretations enhancing reservoir models when integrated with wireline data. \nDrilling Safety & Geomechanics: AI-based identification of splintery cavings enables quantitative pore pressure assessment and wellbore stability evaluation. Cavings can be tied back to source formations using colour and texture signatures\, improving geomechanical predictions.

The International Energy Agency has warned that new development of fossil fuels is incompatible with limiting warming to 1.5 Celsius degrees above pre-industrial level\, which was the strongest target that countries signed up to in the 2015 Paris Agreement. \nHowever\, President Donald Trump rejects the evidence for climate change as a “hoax” and has withdrawn the United States from international action on climate change. He is attempting to thwart domestic action and encouraging fossil fuel companies to “drill baby drill”. Should PESA members also pretend that climate change does not exist\, and support President Trump’s goal of American Energy Dominance? Or is there a better option by supporting the development of carbon capture and storage?

SUMMARY:2026 PESA WEBINAR SERIES: Predicting the Distribution and Connectivity of Fluvial Deposits in the Subsurface Using Scaling Relationships From Present Day River Systems (Adrian Hartley)
DESCRIPTION:2026 PESA Webinar Series\n  \nKindly supported by Rock Flow dynamics  \n  \nThe next webinar as part of the 2026 PESA Webinar Series will take place on Tuesday 23 June 2026. \nThis live webinar will take place at: \n3pm              –     Perth\n4.30pm       –     Darwin\, Adelaide\n5pm                –    Brisbane\, Canberra\, Hobart\, Melbourne\, Sydney \nUse the calendar link on this page to add this event in to your own calendar at the correct local time for your location. \nTickets are free for members (please log in to see this) and $10 for non members. \nPlease buy your tickets and immediately follow the link in the ticket e-mail (not the calendar invite or this webpage\, which is just generic and not event specific) to set up your registration with the webinar software well in advance of the time of the talk.

These relationships are important as they provide a potential mechanism for predicting channel body dimensions from one-dimensional subsurface datasets such as wireline logs or core. Scaling relationships can also aid in reducing uncertainty associated with estimating fluvial channel body width in the rock record\, which\, for a given thickness can vary by between 2 and 5 orders of magnitude.\nLinking present day channel and channel belt dimensions to preserved channel belt sandstone bodies is difficult\, as preserved channel belt stacking patterns are not easily observed in modern day basins. Stacking patterns are related to spatial location in basins and the type of fluvial depositional systems (distributive\, axial or valley). I will show how dimensional data can vary depending on the type of different fluvial depositional systems. Whilst dimensional data from modern day channels and channel belts are not directly transferable to the preserved rock record\, this approach does provide generic relationships that could potentially form the basis for more accurately predicting sandstone body dimensions for subsurface fluid extraction and/or storage.

These contour currents were (and are) usually counter-directional to surface ocean currents and longshore drift patterns that so strongly affect the distribution and movement of sand on the modern and geological pene-contemporaneous shelf areas. The latter longshore vector of sediment transport has thought to be the principal agent for sediment reworking\, sorting by mechanical segregation and movement towards the heads of deep-water systems in both areas\, with the wider shelfal areas contributing more to the reservoir-grade material going through the ‘spin cycle’ that ultimately controls primary fabric when it is resedimented through channels onto the slope and into deeper water. In the northern Gulf of Guinea\, the sediment transport is and was to the east\, whereas offshore Guyana and Suriname it was primarily to the west. \nContour currents\, however\, move in the opposite direction in slope and proximal basin floor settings. These currents impact on the down-slope moving turbidity currents by dislocating the fine suspended load from the flows and depositing them as sediment drifts or enlarged levees or sediment wave fields (or a combination of both) on the western sides of deep-water systems in the northern Gulf of Guinea\, and the eastern parts of deep-water systems on the Guyana-Suriname margin. The impact is profound. Slope channel complexes that are the principal feeder systems to lobe systems outboard on both margins have highly asymmetrical constructional levees in the contour current direction\, and subdued levees in the opposite direction. This impacts on slope channel complex behaviour by showing a steady westward or eastward stacking of the complexes (only one is active at any one time)\, in the direction of the subdued levee. Channel stacking patterns also reflect this asymmetry\, with systematic high-angle lateral offset stack of reservoir channel elements towards the subdued levee. The second impact of the contour current generated asymmetric levee/flanking sediment drift fields is to increase local slope gradients at and near the levee crests\, and this generates lateral channel complex margin collapse into the channel beltways (the highest gradient in the area\, higher than the background slope gradient). It also promotes largescale MTD wasting of the outer levee flanks\, and all slope channel complexes have associated MTDs on the same levee flanks (eastern on the Guyana-Suriname channel complexes for example). \nThe third impact of this channel complex asymmetry because of progressive stacking of channel elements within the beltway\, and progressive stacking of the entire channel complexes in the same direction\, is a mirrored progressive stacking of the outboard lobe complexes\, both on intra slope terraces and on the basin floor. The overall behaviour is completely contour to notions of accommodation space controlling systematic stacking of deep-water channels and lobe complexes. \nExploration\, development and production from a range of prospects and operating fields along both conjugate margins has yielded a fascinating repository of these types of behaviour from mixed turbidite-contourite settings that extend the observations seen on lobe shifting in the Rovuma Basin offshore Mozambique\, and indeed outboard towards the Comoros. Designing line-developed injector-producer wells has necessitated very high angle well design predicated by the channel or lobe element stacking direction to maximise the sand face along hole\, and this has been entirely as a result of the mixed turbidite-contourite influenced behaviour of the slope channel complexes and both intraslope and basin floor lobe complexes. The subsea infrastructure architecture: location of manifolds and the like\, again controlled by the original geology\, needs early alignment to capture the program and reduce cost of facility design and well trajectory complexity.

Generated naturally by geological processes within the Earth\, hydrogen may migrate through the subsurface and accumulate in geological reservoirs. Growing exploration activity\, new drilling programs and evolving regulatory frameworks have attracted increasing interest from the energy\, resources and investment communities. \nThis webinar will provide a general introduction to natural hydrogen and an overview of the current state of this emerging industry. It will examine where natural hydrogen occurs\, the principal geological processes responsible for its generation\, and the geological controls on its migration\, accumulation and preservation. Current exploration approaches will also be reviewed\, including screening of historical datasets\, surface and soil-gas geochemistry\, geophysical methods and exploration drilling. \nThe webinar will also examine recent global exploration activity\, emerging geological play concepts\, resource potential\, economic considerations and the key uncertainties facing the sector. Particular emphasis will be placed on distinguishing encouraging hydrogen occurrences and drilling results from demonstrated\, commercially producible resources.
