Job Title: Senior Petrophysicist

Location: Port Harcourt, Rivers
Job Type: Full-Time
Reports to: Assistant Manager, Petrophysics and Archive Services

Job Summary

• To deliver high-quality petrophysical interpretation, formation evaluation, and operational support for exploration, appraisal, and development wells, for the company’s subsurface and production teams, in order to optimize reservoir understanding, well placement, and hydrocarbon recovery.

Key Responsibilities Areas (KRAs) and Initiatives
Petrophysical Data Acquisition and Quality Control Assurance:

• Design and oversee wireline and LWD logging programs to secure complete and accurate data aligned with each well’s objectives, ensuring operational efficiency and technical integrity, without which reservoir evaluation could be unreliable and production opportunities missed.
• Implement stringent quality control processes during data acquisition, applying borehole and environmental corrections to maintain data accuracy above defined thresholds, ensuring dependable interpretation outcomes and preventing costly re-logging operations.
• Coordinate proactively with drilling, service, and subsurface teams to verify tool selection, depth control, and run sequencing, ensuring efficient execution without which downtime, tool failure, and data gaps may compromise well objectives.
• Monitor real-time logging performance to identify and resolve anomalies immediately, preventing poor-quality or lost data that could hinder reservoir characterization and decision-making.
• Validate post-job data deliverables and approve datasets for corporate storage, ensuring completeness and compliance with standards, without which long-term traceability and reservoir management reliability would be at risk.

Formation Evaluation and Petrophysical Interpretation:

• Integrate multi-source data (logs, cores, pressure, and test results) to derive reservoir parameters such as lithology, porosity, permeability, and fluid saturations, ensuring an accurate description of reservoir quality without which completion and testing decisions may be flawed.
• Apply advanced interpretation techniques (probabilistic, multi-mineral, and uncertainty modeling) to improve precision and confidence in formation evaluation, directly influencing reserves estimation and production strategy.
• Calibrate and validate interpretation outcomes against core and test data to ensure representativity, without which reservoir models could misrepresent hydrocarbon distribution and recovery potential.
• Prepare and communicate formation evaluation summaries that translate technical findings into actionable well completion and production insights critical for well performance optimization and cost-effective development planning.
• Present petrophysical interpretations to multidisciplinary teams, enabling integrated decision-making and reducing risk of misalignment across geology, reservoir, and drilling functions.

Reservoir Characterization and Modeling Integration:

• Develop and maintain robust petrophysical models capturing reservoir heterogeneity, pore structure, and fluid distributions, ensuring accuracy in volumetric calculations and reservoir forecasting.
• Deliver validated petrophysical parameters: Water Saturation (Sw), Porosity (Φ), Net to Gross (NTG), Clay Volume (Vclay), Permeability (k), and cutoffs to support static and dynamic modeling, enabling precise reserves classification and production prediction, without which field development plans may be technically flawed.
• Collaborate continuously with geologists and reservoir engineers to align interpretations and model assumptions, ensuring consistency across all subsurface disciplines and reducing uncertainty in recovery estimates.
• Challenge and refine model inputs and sensitivities to safeguard technical credibility and ensure realism in production forecasts, preventing overestimation of recoverable volumes.
• Participate actively in integrated field reviews and reservoir management sessions, transforming petrophysical insight into operational strategies that maximize recovery and minimize subsurface risk.

Operational Support and Decision Guidance:

• Provide real-time petrophysical analysis during drilling to guide casing depth, well trajectory, and formation testing decisions, without which wells may miss target reservoirs or incur avoidable non-productive time.
• Identify and recommend perforation, coring, and sampling intervals that represent the best reservoir potential, ensuring efficient data acquisition and optimized well productivity.
• Collaborate closely with drilling and production teams to address formation challenges (e.g., pressure anomalies, poor hole conditions), maintaining operational safety and efficiency.
• Offer data-driven input into completion design, stimulation zones, and production testing programs to ensure reservoir sections are optimally exposed, directly improving recovery factors and production outcomes.
• Conduct comprehensive post-well reviews to assess formation evaluation quality, identify workflow improvements, and feed lessons learned into future operations, without which repeat errors and inefficiencies may persist.

Data Governance, Reporting Excellence, and Regulatory Compliance:

• Maintain structured, auditable data management systems for all petrophysical datasets and reports, ensuring accessibility, accuracy, and version control, without which critical data could be lost or corrupted.
• Prepare and submit comprehensive well evaluation reports, log interpretations, and reservoir summaries that meet corporate and regulatory requirements, ensuring transparency and compliance with statutory obligations.
• Enforce strict adherence to internal QA/QC standards and data governance procedures across all petrophysical deliverables, maintaining corporate confidence and data reliability.
• Support internal and external audits by ensuring all data and reports meet compliance, HSE, and governance standards, without which regulatory breaches or license risks could arise.
• Drive digital innovation by adopting automation and analytics tools to enhance efficiency, improve interpretation accuracy, and reduce manual errors, thereby aligning with corporate sustainability and efficiency goals.

Qualifications and Experience Requirements
Minimum Qualification:

• Bachelor’s Degree in Geology, Geophysics, Petroleum Engineering, or a related Earth Science discipline.

Professional Certifications / Accreditations / Registrations:

• Membership of a recognized professional body such as the Society of Petrophysicists and Well Log Analysts (SPWLA), Society of Petroleum Engineers (SPE), Nigerian Association of Petroleum Explorationists (NAPE), or equivalent.

Minimum Years of Experience and Relevant Areas:

• Minimum of 10 years’ relevant experience in petrophysical interpretation and formation evaluation within the oil and gas industry, including at least 3 years in a senior or lead Petrophysicist role.
• Experience in both exploration/appraisal and development/production environments is required.

Proven experience in:

• Planning and supervising wireline and LWD logging operations for exploration and development wells.
• Integrating log, core, and test data to evaluate reservoir properties and hydrocarbon potential.
• Real-time formation evaluation and operational decision support during drilling.
• Petrophysical modeling, uncertainty quantification, and net pay determination.
• Supporting well completion, perforation, and test design through petrophysical analysis.
• Collaborating with integrated subsurface teams for field development planning.
• Using industry-standard software such as Techlog, Geolog, or Interactive Petrophysics (IP).
• Reservoir surveillance and production optimization using log-based saturation monitoring.

Any Additional Qualifications / Certifications or Experience (Desirable but not essential):

• Master’s degree in petroleum engineering, Geoscience, or related field.
• Certification in Advanced Petrophysics, Formation Evaluation, or Data Analytics.
• Experience with digital petrophysics or machine learning applications in subsurface analysis.
