Main Purpose:

The Senior Lead Petrophysicist will lead petrophysical evaluations across exploration, appraisal, and development wells, ensuring high-quality data acquisition and reservoir characterization. The role involves advanced log interpretation, core-log integration, and application of digital/AI techniques to optimize reservoir understanding and investment decisions. This position also requires stakeholder engagement and mentoring of junior professionals to drive technical excellence.

Job Responsibilities:

• Lead Petrophysical activities for exploration, appraisal, and development wells.
• Design and oversee logging programs (LWD/Wireline), including tool selection, vendor coordination, and real-time monitoring.
• Conduct formation evaluation—porosity, saturation, lithology, and hydrocarbon volumes—and integrate results into subsurface models and documentation.
• Attend rig site operations while logging and coring activities to provide real-time decision support during drilling.
• Co-ordinate to execute coring programme and associated laboratory studies to ensure high quality deliverables.
• Perform field quality control (QC) of logging operations and ensure data integrity across all acquisition phases.
• Collaborate with cross-functional teams such as drilling, geology, reservoir engineering, geophysics, and related teams to deliver petrophysical insights and optimize data acquisition strategies.
• Integrate petrophysical data with core study results (RCA/SCAL), advanced logs, and provide inputs for seismic interpretation, geological modeling and resource estimation.
• Analyse advanced logs (e.g., NMR, Formation Tester, Imaging, Sonic Scanner etc.) and develop workflows for evaluating conventional, unconventional, and tight reservoirs.
• Evaluate petrophysical uncertainties and their impact on volumetric resource estimates and support for high grading the prospects.
• Analyse and interpret cased hole and production logs to evaluate reservoir behaviour, diagnose well performance, and guide optimization strategies.
• Engage proactively with partners, regulators, and third-party stakeholders to ensure alignment and compliance across all technical, operational, and strategic dimensions.
• Leverage machine learning and AI techniques to enhance petrophysical interpretation, automate workflows, and improve reservoir characterization.
• Scout emerging technologies to improve efficiency and reduce costs in data acquisition and interpretation.
• Evaluate farm-in/farm-out opportunities and deliver petrophysical assessments to support investment decisions.
• Manage well log data systems, QA/QC processes, and reporting standards.
• Mentor and train junior Petrophysicists and lead training initiatives to promote technical excellence and knowledge sharing.

Qualifications & Experience:

• Master’s degree or higher in Geophysics from a recognized university.
• Minimum 15+ years of experience in Petrophysics domain within the oil & gas industry.
• Willing and able to travel offshore for rig site operations and field quality control.
• Proven track record in offshore exploration, appraisal, and development projects.
• Experience with major or international oil companies highly desirable.
• Exposure to Production Sharing Contract (PSC) environments and regional regulatory frameworks preferred.

Technical Skills:

• Proficient in industry-standard petrophysical software (e.g., Techlog, Geolog, Interactive Petrophysics).
• In-depth knowledge of logging tools, acquisition systems, and core-log-seismic integration workflows.
• Skilled in advanced interpretation techniques, including rock physics, facies classification and saturation modelling.
• Experience with complex reservoir types: Clastics, carbonates, and unconventional plays (e.g., shale, tight gas).
• Hands-on experience in machine learning and data analytics applications in petrophysical evaluation.
