It has a primary listing on the Nigeria Stock Exchange and a secondary listing on the Johannesburg Stock Exchange. With shared values of Teamwork, Respect, Integrity, Passion and Professionalism (TRIPP).

Job Description:

• To perform petrophysical interpretation, formation evaluation, and logging data quality assurance in support of exploration, appraisal, and development wells.
• The role contributes to reservoir characterization and well performance optimization by integrating log, core, and test data to support subsurface teams in making informed decisions on drilling, completion, and reservoir management.

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

• Support the planning and execution of wireline and LWD logging programs by reviewing proposed tool strings and data acquisition plans to ensure alignment with well objectives and reservoir evaluation requirements.
• Assist in reviewing logging job deliverables to confirm completeness, accuracy, and compliance with company standards prior to incorporation into corporate databases.
• Conduct routine quality control checks on acquired logging data, including depth matching, environmental corrections, and validation of tool responses to ensure datasets are suitable for interpretation.
• Work with drilling teams and logging service companies during data acquisition to monitor logging operations and promptly flag data quality issues or operational anomalies that may affect formation evaluation.
• Maintain documentation of logging programs, acquisition parameters, and QC results to support traceability and future data analysis.

Formation Evaluation and Petrophysical Interpretation:

• Interpret open-hole logs using established petrophysical workflows to derive reservoir parameters, including lithology, porosity, water saturation, and shale volume.
• Support formation evaluation studies by integrating well logs with mud logs, core measurements, pressure data, and well test results to improve understanding of reservoir characteristics.
• Apply deterministic interpretation models to evaluate hydrocarbon-bearing zones and determine net reservoir intervals across exploration and development wells.
• Prepare formation evaluation summaries and interpretation reports that clearly communicate reservoir characteristics and uncertainties to subsurface teams..
• Participate in multidisciplinary technical discussions to ensure petrophysical findings are aligned with geological and reservoir engineering interpretations.

Reservoir Property Analysis and Modeling Support

• Generate petrophysical parameters such as Water Saturation (Sw), Porosity (Φ), Net to Gross (NTG), Clay Volume (Vclay), and permeability estimates for use in static reservoir models.
• Support calibration of log-derived properties with core analysis and laboratory data to improve the accuracy of reservoir characterization outcomes.
• Provide petrophysical inputs and datasets required for volumetric calculations and reserves estimation workflows.
• Assist in identifying reservoir heterogeneity and petrophysical trends across wells that may influence reservoir performance and development planning.
• Assist in updating petrophysical interpretations as new wells are drilled or new datasets become available.

Well Operations and Formation Evaluation Support:

• Assist in real-time log interpretation during logging operations to support operational decision-making and ensure accurate reservoir identification.
• Work with drilling and wellsite personnel to address logging-related challenges and ensure continuity of formation evaluation programs.
• Recommend potential zones for coring, pressure measurements, and formation testing based on log interpretation.
• Collaborate with drilling engineers and service companies to resolve formation evaluation challenges encountered during well operations.
• Participate in post-well evaluation activities to review data quality, interpretation outcomes, and lessons learned for future wells.

Data Management, Documentation, and Technical Reporting:

• Ensure petrophysical datasets, interpretations, and supporting documentation are properly stored and maintained within corporate data management systems.
• Prepare log interpretation plots, petrophysical summaries, and supporting analysis for well evaluation reports.
• Enforce strict adherence to internal QA/QC standards and data governance procedures across all petrophysical deliverables, maintaining corporate confidence and data reliability.
• Support corporate data governance initiatives by maintaining organized records of log data, interpretation parameters, and reservoir evaluation results.
• Contribute to continuous improvement of petrophysical workflows through documentation of best practices and lessons learned.

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 3–5 years’ relevant experience in petrophysical interpretation and formation evaluation within the oil and gas industry.
• Experience supporting exploration, appraisal, or development wells is desirable.

Proven experience in:

• Planning and supporting wireline and LWD logging programs.
• Performing petrophysical interpretation of open-hole logs.
• Integrating log, core, and test data to evaluate reservoir properties.
• Supporting real-time formation evaluation during drilling operations.
• Providing petrophysical inputs for reservoir characterization studies.
• Collaborating with integrated subsurface teams for field development planning.
• Supporting reservoir management through log-based analysis and monitoring.
• Using industry-standard software such as Techlog, Geolog, or Interactive Petrophysics (IP).

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

• Master’s degree in Petroleum Engineering, Geoscience, or related field.
• Training in advanced formation evaluation or petrophysical interpretation workflows.
• Experience with digital data management systems or automated interpretation tools.
