Mitch Allison

• Project manager for the Otway Infrastructure Project which included the incident free delivery of the CRC-8 well which included directional drilling, coring, wireline logging and analysis in December 2023. The project also included the recompletion of the existing CRC-3 injection well with a two-zone completion in June 2024. • Project manager for the Otway Shallow Fault Project which included the injection of ~16 tons of CO2 into shallow Port Campbell Formation and included seismic vintages, Fibre Optic (Acoustic, strain and temperature) data and surface soil flux. • Management of multiple stakeholders (universities, international research and government organisations) and ownership of the $16 million Otway Infrastructure Project and the $3.5 million Shallow Fault Project budgets. • Otway International Test Centre HSE and operational oversight which included discussions with regulators from the petroleum, EPA and local government/councils. • Operational focal point for additional projects including the 10,000 tonne GeoCQuest Field Validation injection in November 2024 and associated seismic operations.

• Analysis of Australian Basins (Perth, Otway, Surat) for CCS suitability including static model generation and associated storage volume estimations. • Assisted with the development of a Declaration of Storage for regulatory submission. • Developed static models and workflows for clients as well as shallow and deep CCS projects in the Otway Basin.

• Project lead for subsurface studies within the Cooper Oil team. • Led subsurface studies through the Santos assurance gating process including generation of static models, volumetrics, geologic risking and assistance with economics. • Liaised with multiple departments within Santos to streamline subsurface studies with the goal of adding value without effecting safety. • Assisted in generation of Petrel workflows, data integration and static model standardization. • Mentored graduate geologists/team members with emphasis on Petrel software, geologic processes and well operations.

• Acting Exploration Manager (reporting directly to the CEO) from January to May 2019, subsurface focal point for Government, JV and Central management across exploration portfolio. • Central Petroleum Operating Committee Representative for Southern Amadeus JV with Santos and authorised representative for permit administration with the Northern Territory and Queensland Governments. • Analyze and develop recommendations to management for acreage releases in Queensland and NT, as well as potential farm-ins and acquisitions. • Assist in generation of company ASX announcements, as well as quarterly and annual reports. • Generated the subsurface budget for Central’s exploration permits, with an emphasis on a forward plan for exploration and appraisal. • Assist in the development of play-based exploration maps and the development of a seriatim based leads and prospects database, utilizing stochastic volumetrics and well production type-curves to develop economics and geologic risk. • Generate static models for the Mereenie, Palm Valley, Dingo and Range CSG fields in Petrel. Iterate with input from reservoir engineering team and interface with reserve auditors to develop reserves, resources and FDP’s. • Analyze & interpret new & legacy well data with the focus on developing a greater understanding of the conventional and unconventional rock properties in the Amadeus and Southern Georgina Basins.

• Design & implement exploration & appraisal wells for Jurassic & Permian aged CSG & shale gas plays. Focal point for day-to-day drilling operations & government compliance. • Apply petrophysical log analysis techniques to determine porosity, permeability, water, gas & oil saturations & Net to Gross maps which lead into creating volumetrics. • Utilize Petrel to run risk & uncertainty analysis to determine the variance of the petrophysical properties within the static model. • Interpret & apply wellbore stress studies to determine pervasiveness of natural fracturing & stress orientations within basins. • Collaborate with reserve auditors NSAI for resource & reserve bookings. 100 BCF maiden resources in Bowen & Surat Basin, as well as 50 BCF 3P reserve upgrades in the Bowen Basin. • Analyze & evaluate conventional & unconventional play/prospects through old well completion reports, logs, seismic & regional studies.

• Focal point for operations geology withing Roma CSG in the Surat basin. • Interpret laboratory results from coal samples of Jurassic & Permian aged coals & generate/update coal property maps. • Design highly complex well trajectories within the Petrel static model. • Investigate applicable technologies for data acquisition, interpretation & analysis. • Operations geology input to Field Development Plans for the Roma CSG fields. • Optimize approach to development activities in conjunction with drilling, completions & production teams.

• Managed drilling programs (30+ wells a year) & geological services in deviated & horizontal wells for Cretaceous aged coalbed methane & conventional gas wells. • Evaluated regional coalbed methane properties to define sweetspots and bypassed production potential. Assisted in development of reserve estimates. • Created detailed structural & isopach maps, as well as, thickness, gas content & OGIP maps using Petrel. • Evaluated coalbed methane prospectivity in landsales and competitor lands.
