Geoscience Consultant

Overview

Role Overview

Subsurface Interpretation & Prospect Generation

• Lead integrated geological and geophysical interpretation of 2D/3D seismic data, well logs, core data, and regional studies to identify and mature exploration prospects and leads.
• Develop and maintain detailed geological models including structural, stratigraphic, and sedimentological frameworks for key basins and play types.
• Generate and rank a portfolio of exploration prospects, quantifying volumetrics (GRV, STOIIP, GIIP) and geological risk using probabilistic methods.
• Conduct basin analysis, source rock evaluation, and petroleum systems modeling using software such as PetroMod or BasinMod.

Seismic Interpretation & Geophysical Analysis

• Perform advanced interpretation using industry-standard tools (Petrel, Kingdom, OpendTect), including attribute analysis, AVO/DHI evaluation, and inversion studies.
• Collaborate with geophysicists to design seismic acquisition programs and evaluate seismic processing quality and fit-for-purpose outputs.
• Integrate seismic data with well control to calibrate stratigraphic and structural models.

Well Planning & Drilling Support

• Provide geoscientific input to well prognosis documents, including formation tops, expected lithologies, pore pressure forecasts, and geological objectives.
• Monitor drilling operations in real-time, updating subsurface models with incoming formation evaluation, mud log, and MWD/LWD data.
• Conduct post-well analysis and documentation to capture learnings and update the geological model.

Resource Estimation & Reserves Assessment

• Prepare and peer-review PRMS-compliant resource estimates (Prospective Resources, Contingent Resources, and Reserves) for exploration and appraisal assets.
• Apply Monte Carlo simulation and decision-tree methods for uncertainty quantification and portfolio risk analysis.
• Represent subsurface findings in CPR (Competent Person Reports) and regulatory submissions.

Technical Leadership & Mentorship

• Act as technical mentor and coach to junior and mid-level geoscientists, supporting their professional development and competency frameworks.
• Lead and facilitate peer reviews, technical assurance gates (ToR/FDP), and stage-gate evaluations for exploration and appraisal projects.
• Present complex geoscientific findings to senior management, joint venture partners, investment committees, and regulatory bodies.

Collaboration & Stakeholder Engagement

• Work in integrated project teams with reservoir engineers, petrophysicists, drilling engineers, facilities planners, and commercial analysts.
• Engage with national oil companies (NOCs), government regulatory agencies, and JV partners on geoscientific matters.
• Support new business development activities including farm-in/farm-out evaluations, license round submissions, and M&A due diligence.

Education

• Bachelor's degree (BSc) in Geoscience, Geology, Geophysics, or Earth Sciences — required.
• Master's degree (MSc) or PhD in a relevant geoscience discipline — strongly preferred.

Experience

• Minimum 8 years of progressive experience in subsurface geoscience within the oil and gas industry.
• Proven track record in exploration, appraisal, and/or development geoscience across at least two different geological settings or basins.
• Demonstrated experience in multi-disciplinary integrated team environments.
• Prior experience working in or alongside national oil companies, IOCs, or independent E&P operators.

Technical Skills

• Advanced proficiency in seismic interpretation software (Petrel, Kingdom, OpendTect, or equivalent).
• Proficiency in basin modelling software (PetroMod, BasinMod, or equivalent).
• Working knowledge of formation evaluation, well log interpretation, and petrophysical principles.
• Strong understanding of PRMS resource classification framework and associated reporting standards.
• Familiarity with AVO analysis, seismic inversion, and geomechanical concepts.
• Experience with GIS-based tools (ArcGIS, QGIS) for regional mapping and data integration.

Preferred Skills & Competencies

• Professional certification: AAPG Certified Petroleum Geologist (CPG), SEG or equivalent professional body membership.
• Experience with unconventional resources (tight oil, shale gas, coal bed methane).
• Knowledge of deepwater, HPHT, or frontier exploration environments.
• Familiarity with carbon capture (CCS) site characterization and assessment.
• Experience leading CPR processes and engaging with independent auditors.
• Proficiency with Python scripting or R for subsurface data analytics.
• Working knowledge of EAGE, SPE, and AAPG research literature and technical standards.
