Job Description
Job Purpose
• The Production Geologist will work within a dynamic, high‑performing, multi‑disciplinary team, providing technical leadership and delivery across one of the following areas, depending on either role assignment below:
Studies:
• Deliver a step change in reservoir characterisation and modelling across the full Opportunity Realisation Process, from opportunity identification through to Final Investment Decision FID.
• The role is accountable for front‑end project delivery and supports the achievement of the company’s growth ambitions.
Operations:
• Provide production geology support to deliver top‑quartile well proposals, well execution activities new wells, workovers, and abandonment, and the systematic capture and documentation of learnings from delivered well projects.
• The role also provides Production Geology discipline support to Field Management teams within the wider Asset organisation, including WRFM and hydrocarbon resource management activities.
Responsibilities
Studies Production Geologist:
• Analyse and integrate relevant geoscience dataseismic, well logs, bio-strat, cores, SWS etc. to develop robust static reservoir models.
• Generate realistic depth maps from production seismology outputs, honouring key geological controls such as fluid contacts, well tops, fills, and seismic amplitudes.
• Undertake small to medium-scale seismic interpretation projects as required.
• Deliver compliant static models, including the quantification of static subsurface uncertainties and effective transfer of models to Reservoir Engineers.
• Collaborate with Well Engineers to plan and optimise well paths while identifying and mitigating potential drilling hazards.
• Contribute to integrated milestone reviews, presenting technical work for endorsement and ensuring timely approval by relevant Technical Authorities.
• Provide Production Geology PG discipline support within integrated teams, ensuring no project milestone slippage attributable to geoscience inputs.
• Support the timely delivery of project maturation milestones through compliant and fit‑for‑purpose PG subsurface evaluations.
For an Operations Production Geologist:
• Analyse and integrate geoscience data seismic, well logs, production data, etc. to support the development of high‑quality well proposals.
• Work closely with Well Engineers to plan and optimise well trajectories, ensuring well objectives are achieved while mitigating geological and drilling risks.
• Coordinate the preparation of well proposals and ensure compliance with mandatory PG, DEM1, and DEP standards.
• Act as geological liaison and Wellsite PG/PE, supporting the safe and effective delivery of planned wells and ensuring clear communication of well outcomes; this responsibility may extend across multiple assets.
• Ensure the timely documentation of PG inputs and coordinate mandatory End‑of‑Well Reports EOWR for all drilled wells.
• Participate in internal and external stakeholder engagements, including the presentation of preliminary well results to regulatory authorities and JV partners, and addressing PG‑related queries.
• Provide PG support to other asset clusters in screening WRFM opportunities, maturing WRFM proposals, and delivering HCIIP for assigned fields, as required.
