Senior Petrophysicist

Qualification & Experience

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

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.
  

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.
  

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.
  

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.
  

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.
  

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.
