PESA QLD: Lunch Presentation, 21st July – Mike Martin and Justin Gorton

Thursday, 21 July, 2022 @ 12:15 pm - 2:00 pm (Australia/Brisbane time)

Free – $100.00

Guest Speaker(s): Mike Martin and Justin Gorton


Justin Gorton is the G&G Team Lead and Principal Geologist for Westside Corporation. He has worked within the oil and gas industry for over 15 years in operational, technical, and leadership roles across the private and public sectors.  A good part of his career has been spent directly overseeing exploration and appraisal campaigns across various basins in Australia to assess, discover, and mature coal seam gas and other unconventional resources. In his current role, he is responsible for leading the maturation and development of WestSide’s Queensland assets. His qualifications include a Bachelor of Science in Geological Sciences from University of Oregon and Honours from La Trobe University in Melbourne. Justin is a member of the American Association of Petroleum Geologists (AAPG), The Petroleum Exploration Society of Australia (PESA), and past President of the Formation Evaluation Society of Queensland (FESQ).


Mike has a degree in Earth Sciences and PhD in sequence stratigraphy and sedimentology.  He has spent the last 30 years working around the world in a variety of consulting and operated oil and gas company roles.  He moved out to Australia in 2012, with BG Group, and has pored over the Surat and Bowen Basin sediments since 2009.  He is currently the Geoscience Manager at Westside Corporation overseeing the development of their Greater Meridian CSG fields in the Bowen Basin, exploration and appraisal of other Bowen Basin ATPs and appraisal and development of their oil and gas fields in New Zealand’s Taranaki Basin.


This month PESA Queensland welcomes Mike Martin and Justin Gorton to present a technical luncheon entitledTransformation of Australia’s first commercial CSG field into a major gas project: How drilling innovation and subsurface understanding have driven success”.

The Technical Lunch will be held at the Brisbane Hilton Hotel, in the Victoria Room with access from the Hilton Main Foyer on Level 6.

For detailed directions, see explanation below.

Please note the Early Bird ticket pricing cut-off times described below.

Presentation Abstract:

Transformation of Australia’s first commercial CSG field into a major gas project: How drilling innovation and subsurface understanding have driven success


Note this talk is a much extended version of what was recently presented at APPEA.


The discovery of coal seam gas (CSG) in what was known as Dawson Valley Area dates to 1991, when it was operated by Mt Isa Mines. It was the first commercial coal seam gas field in Australia, with production and sales of gas commencing in 1996, then operated by Conoco and known as Meridian SeamGas.


In 2010, Westside Corporation transitioned from explorer to producer by acquiring a 51% operating interest in Meridian SeamGas from Anglo American (Anglo) and Mitsui Moura Investment Pty Ltd (MMI). Over the last 10 years that Westside has taken production from <5 terajoules per day (TJ/D) to 42 TJ/D with gas being sold to both domestic and export markets. Further acreage acquisition to the north and south effectively doubled the asset; now known as The Greater Meridian Fields.


The steep rise in gas demand, complex market dynamics, regulatory environment, and competition from large global oil and gas operators makes it a challenging environment for smaller gas producers in Australia. The ability to remain agile and employ innovative approaches to optimize field development are key success factors for Westside’s growth. In particular, the utilisation of pad-based drilling of multi-lateral wells has reduced cost and surface footprint, whilst enabling more efficient drainage of reservoirs.


To support these approaches in field development, a more robust subsurface framework was required. Adequate knowledge on the distribution and variability of coal thickness, gas content/composition, structure, geomechanics, and geohazards forms the basis of the static model. It is used both for resource definition and for the optimal planning and execution of multi-lateral wells; reducing drilling risks.


This talk will describe elements of the subsurface static model, the advancement of drilling and completion approaches and how these have contributed to further optimization of economic development and production of gas from the Greater Meridian Fields.
