The Senior Petrophysicist will be responsible for delivering high-quality petrophysical interpretation, formation evaluation, and operational support across exploration, appraisal, and development wells. The role supports subsurface and production teams in improving reservoir understanding, optimizing well placement, and enhancing hydrocarbon recovery outcomes.

Petrophysical Data Acquisition and Quality Control Assurance:

• Design and supervise wireline and LWD logging programs aligned with well objectives to ensure accurate and complete data acquisition.
• Implement quality control procedures during data acquisition, including borehole and environmental corrections to maintain data accuracy standards.
• Coordinate with drilling, service, and subsurface teams to ensure correct tool selection, depth control, and efficient logging operations.
• Monitor real-time logging data to detect and resolve anomalies promptly and maintain data integrity.
• Validate and approve post-job datasets for corporate storage in compliance with data standards.

Formation Evaluation and Petrophysical Interpretation:

• Integrate logs, core data, pressure data, and test results to determine reservoir properties such as lithology, porosity, permeability, and fluid saturation.
• Apply advanced interpretation methods including probabilistic, multi-mineral, and uncertainty modelling techniques.
• Calibrate interpretations against core and test data to ensure accuracy and reliability.
• Prepare formation evaluation reports to support completion and production decision-making.
• Present interpretation results to multidisciplinary subsurface teams for integrated decision-making.

Reservoir Characterization and Modeling Integration:

• Develop petrophysical models representing reservoir heterogeneity, pore structure, and fluid distribution.
• Provide validated petrophysical parameters including Sw, porosity, NTG, clay volume, permeability, and cutoffs for reservoir modelling.
• Collaborate with geologists and reservoir engineers to align interpretations and model assumptions.
• Refine model inputs and assumptions to improve forecast reliability.
• Participate in integrated field reviews and reservoir management sessions.

Operational Support and Decision Guidance:

• Provide real-time petrophysical input during drilling operations for casing, trajectory, and testing decisions.
• Recommend perforation, coring, and sampling intervals based on reservoir quality.
• Support drilling and production teams in resolving formation-related challenges.
• Contribute to completion design, stimulation planning, and production testing strategies.
• Conduct post-well reviews and document lessons learned for continuous improvement.

Data Governance, Reporting Excellence, and Regulatory Compliance:

• Maintain structured and auditable petrophysical data management systems.
• Prepare and submit well evaluation reports and reservoir summaries in line with corporate and regulatory requirements.
• Ensure adherence to QA/QC standards and data governance procedures.
• Support audits by ensuring compliance with HSE and regulatory standards.
• Support digital transformation through adoption of automation and analytics tools.

Requirements & Qualifications

• Bachelor’s Degree in Geology, Geophysics, Petroleum Engineering, or related Earth Science discipline.
• Membership of professional bodies such as SPWLA, SPE, NAPE, or equivalent.
• Minimum of 10 years’ experience in petrophysical interpretation and formation evaluation in the oil and gas industry.
• At least 3 years in a senior or lead Petrophysicist role.
• Experience in exploration/appraisal and development/production environments.

Proven experience in:

• Wireline and LWD logging operations planning and supervision.
• Integration of log, core, and test data for reservoir evaluation.
• Real-time formation evaluation during drilling operations.
• Petrophysical modelling, uncertainty analysis, and net pay determination.
• Supporting well completion and testing design.
• Collaboration with multidisciplinary subsurface teams.
• Use of software such as Techlog, Geolog, or Interactive Petrophysics (IP).
• Reservoir surveillance and production optimization.

Additional (Desirable):

• Master’s Degree in Petroleum Engineering, Geoscience, or related field.
• Advanced certification in Petrophysics, Formation Evaluation, or Data Analytics.
• Experience with digital petrophysics or machine learning applications.
