Senior Geologist

Posted On : August 12, 2025

Location : Kuala Lumpur

Job Function : Subsurface

Employment Type : Permanent

The Senior Geologist reports directly to the Manager, Geology and is responsible for leading geological studies and 3D geological modelling across the full exploration and production cycle. This includes integrating subsurface and production data to develop comprehensive geological models that support optimal well placement for exploration, appraisal, and development. Strong expertise in geological modelling is essential for effective collaboration within a multidisciplinary technical team. The role also involves managing subsurface projects, reserves, production forecasts, and exploration activities to maximize economic recovery and asset value.

KEY ACCOUNTABILITIES

• Conduct geological assessments and studies for new ventures, exploration, and mature field opportunities.
• Build and maintain 3D static reservoir models integrating various subsurface and production data to accurately represent reservoir architecture and hydrocarbon volumes.
• Maintain comprehensive field-scale well correlations to define reservoir flow units, connectivity, and continuity for mapping and modelling purposes.
• Integrate all relevant subsurface data (e.g., stratigraphy, petrophysics, pressure, seismic) into reservoir model construction.
• Conduct pre-drill subsurface risk assessments, generate volumetrics, and prioritize leads and prospects.
• Lead geoscience efforts within integrated teams, working closely with reservoir engineers, petrophysicists, and production technologists.
• Prepare well proposals and formation evaluation programs to meet reservoir characterization needs.
• Support drilling operations with geological input and real-time monitoring in collaboration with operations and wellsite geologists.
• Coordinate with drilling teams to identify and mitigate geohazards and ensure safe, efficient drilling campaigns.
• Contribute geological input to Field Development Plans (FDPs).
• Perform deterministic and probabilistic volumetric assessments for reserves reporting and audits.
• Plan and oversee geological lab analyses of rock and fluid samples according to industry standards.
• Ensure all reports, presentations, and technical documentation are of high quality and delivered on time.
• Participate in data rooms, analyse subsurface data, and provide recommendations on new opportunities.
• Mentor and coach junior geologists to support their professional growth.
