SUMMARY:PESA NSW October 2026 Technical Lunch: Horizon Oil
DESCRIPTION:Sinphuhorm & Nam Phong Gas Fields\, Northeast Thailand \nIn August 2025\, Horizon Oil and Matahio Energy acquired ExxonMobil’s interests in the Sinphuhorm and Nam Phong gas fields\, located on the Korat Plateau in northeastern Thailand. Nam Phong\, now operated by MH Energy Thailand\, the local Thai entity established by Horizon Oil and Matahio Energy\, is the older of the two fields and has been producing gas since the 1980s. Sinphuhorm\, discovered later\, commenced production in 2006 and is operated by Thailand’s national oil company\, PTTEP. Together\, the fields supply gas to the Nam Phong Power Plant\, which provides a significant portion of the electricity demand across northeastern Thailand. \nThe regional geology comprises a thick succession of Triassic to Cretaceous continental clastic sediments overlying Permian carbonate platforms\, which form the primary reservoirs in both fields. Deposited in a warm\, shallow marine environment\, these carbonates have undergone multiple phases of diagenesis\, tectonic fracturing\, and dissolution. Subsequent episodes of extension and structural inversion exposed carbonate highs to prolonged meteoric and burial dissolution\, creating an extensive network of caves\, vugs\, and collapse breccias. Later tectonic deformation further enhanced reservoir complexity through the development of fracture systems\, resulting in highly heterogeneous reservoirs characterized by a combination of structural and diagenetic porosity. \nAs relatively new entrants to these assets\, Horizon and Matahio are leveraging PTTEP’s extensive operational experience and subsurface knowledge to accelerate understanding of the fields. A key challenge is integrating seismic attributes\, well data\, and production performance to better characterize reservoir architecture and predict reservoir behaviour. This integrated approach is particularly important for identifying and optimising future infill drilling opportunities within these fractured and karstified carbonate systems. \nOngoing work is focused on translating the geological complexity of the reservoirs into a robust subsurface framework that improves reservoir prediction and reduces development uncertainty. By combining geological\, geophysical\, and production data\, the current work aims to support more confident field development decisions and enhance the long-term gas deliverability of both Sinphuhorm and Nam Phong. \n

SUMMARY:PESA WA: October Technical Evening Presentation: Professor Chris Elders
DESCRIPTION:PESA WA invites you to our October Technical Evening Presentation on Tuesday 20 October at The Shoe Bar:\n“The Peculiarities of Australia’s Northern and Western Margins”\nPresented by Professor Chris Elders (Elders Earth Sciences and Curtin University)\n\nDeep seismic profiles collected from continental margins around the world over the past 20 years have shown that there is no such thing as a “typical” passive continental margin. The role of structural inheritance (the influence of older structural fabrics on subsequent events) and multiple\, distinct phases of rifting are some of the factors that contribute to variety and complexity. Recently completed PhD projects at Curtin University allow us to investigate this further in the context of the northern and western margins of Australia. These show that Paleozoic rifts that propagated east across the Northern Carnarvon and Roebuck basins and south along the western margin of Australia exerted a significant control on subsequent structural architecture and stratigraphy. The differences in the intensity of deformation may account for some of the contrasting features of these margins and in particular\, set up the conditions for the accumulation of thick sequences of Triassic sediments in the Northern Carnarvon Basin depocentre. Being better able to quantify the extent of Permian rifts raises some interesting questions for tectonic reconstructions and the distribution of subsequent Mesozoic rift episodes but helps to explain the morphology of the resulting passive margin and the sedimentary processes that operated on it. \n\nTicket Prices: \nMember: $30.00 \nStudent Member: $10.00 \nConcession Member [Retired or Hardship]: $20.00 \nNon-Member: $40.00 \nAll ticket sales close at 5pm Monday 19 October.  No further tickets will be allocated after this time. \nPlease note that this event will be held on Tuesday 20 October at The Shoe Bar (Yagan Square). Doors open at 5.30pm with the presentation commencing at 6pm. \nHosted with thanks to our Platinum Sponsor: \n \nand Gold Sponsor: \n \nand Silver Sponsors: \n \n \n \nand Bronze Sponsor:

SUMMARY:PESA SA/NT and SPE-SA October Luncheon 2026
DESCRIPTION:PESA SA/NT and SPE-SA October Luncheon\n“Geological CO₂ Storage: Familiar Subsurface\, Different Questions”\nDr. Katherine Romanak\nThe University of Texas at Austin’s Bureau of Economic Geology \n  \nAbstract \nGeological CO₂ Storage: Familiar Subsurface\, Different Questions \nPetroleum geoscientists come to CO₂ storage with a powerful advantage: the rocks\, wells\, fluids and subsurface tools are familiar. But CCS can change the meaning of familiar observations—and sometimes reverse the questions we are accustomed to asking. Injection is not simply production done backwards. When is migration expected\, and when is it a containment concern? Does movement outside a predicted plume represent failure? Can there be environmental impact without CO₂ leakage? And when does a storage issue become a reportable emission? This presentation will explore where petroleum experience transfers directly to geological CO₂ storage and where familiar concepts need to be reconsidered. Drawing on examples from storage projects\, monitoring research\, and controlled-release experiments\, it will distinguish three objectives that are often unintentionally conflated: demonstrating containment\, protecting the environment\, and accounting for emissions. The central argument is simple: before deciding what to monitor\, we must first be clear about the question the monitoring is meant to answer. That distinction has important consequences for how we define leakage\, interpret unexpected subsurface behavior\, assess environmental risk\, and demonstrate that CO₂ storage is both safe and effective. \nEvent Details:\nThursday\, 22 October 2026 \nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 19th October  2026 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA WA: Rottnest Island Field Trip
DESCRIPTION:PESA WA: WADJEMUP (ROTTNEST) FIELD TRIP –\nCorals\, Calcareous aeolianites & Quokkas – By Bike\nPESA WA is hosting a field trip to Rottnest Island in September 2026.  This is a fantastic opportunity to explore the region\, engage directly with field activities\, and deepen your understanding of the area’s geological context. \nWadjemup (Rottnest Island) is dominated by the Tamala Limestone\, an extensive unit of Pleistocene carbonates that outcrops along large parts of the West Australian margin between Shark Bay and Esperance. It contains the one of the world’s most significant deposits of carbonate aeolianites (wind-blown carbonates\, deposited in dunes) which can be clearly seen in many of the outcrops. However\, Pleistocene to Recent sea-level fluctuations have left behind a variety of other deposits and features – in-situ corals\, shallow marine sediments\, elevated platforms and notches\, salt lakes\, dunes and modern coral reefs. \nA c. 17 km cycling tour of the island\, taking in sights at Salmon Point\, Fairbridge Bluff\, the Lighthouse\, Mt Herschell Quarry\, and Geordie Bay will enable us to examine these different features. We will follow a circular route\, with a scenic stop to eat our packed lunches (please bring your own) and return back to the settlement in time for refreshments before the ferry returns to Perth. \nPlease note that for insurance reasons this trip is only open to members. If you are not currently a member you will need to sign up before booking. \nGetting there: \nThe trip begins at 09.20 at the signpost outside the visitor’s centre at the entrance to the pier.  However you travel\, you must be at this meeting point\, with your bicycle by this time. \nIf you are coming over on the ferry for the day\, the recommended ferries are: \n\n\n\n\ndepart from\ntime\narrive to\ntime\n\ndepart from\ntime\narrive to\ntime\nlist price\nbike hire\nbike freight\n\n\nRottnest express\nFreo B shed\n0830\nRottnest\n0900\n\nRottnest\n1630\nFreo B shed\n1700\n$85.00\n$38.00\n$21.00\n\n\nSealink\nFreo B shed\n0800\nRottnest\n0830\n\nRottnest\n1700\nFreo B shed\n1730\n$83.14\n$37.00\n$20.00\n\n\nRottnest fast ferries\nHillarys\n0730\nRottnest\n0815\n\nRottnest\n1630\nHillarys\n1715\n$96.00\n$29.00\n\n\n\n\nVarious discounts are available on ferry bookings through certain memberships (RAC\, HBF\, entertainment book etc.) \n  \nFieldtrip Leader: Chris Elders and Mark Taylor \nCost: \n\nAttendance is open only to PESA members.  Non-members must join PESA to attend.\n$30.00 per person (Note: This price is for the instruction only.
