Senior Petrophysicist

Job category: Subsurface and Petroleum Engineering
Job type: Full time
Location: Lagos

Major areas of responsibility

• Support development, exploration and appraisal planning and execution activities.
• Provide discipline input for fast-paced integrated evaluations with limited time and data, for onshore and offshore assets.
• Plan safe well and reservoir data acquisition programmes with other geoscientists and engineers for exploration, appraisal and development wells; supervise and quality-assure data acquisition.
• Provide timely evaluation and interpretation of well and reservoir data (log and core) to help understand subsurface uncertainties.
• Evaluate formation and fluid properties that underpin field and reservoir resource estimation, development and management, with clear documentation of fluid distribution and reservoir properties.
• Interpret and evaluate old and new cased-hole logs for casing and tubing integrity.
• Provide geomechanical modelling to support casing design.
• Prepare pore pressure and fracture gradient and shallow hazard assessments for well delivery plans, as required.
• Support well delivery plans on well placement, orientation and data acquisition programmes.
• Plan and supervise log data acquisition in producing wells for flood-front monitoring and reservoir performance optimisation, and propose additional testing for P&A plans.
• Coordinate with Geophysics on quantitative interpretation (QI) work.
• Support C&P in evaluating data acquisition plans.
• Collaborate with geologists, reservoir engineers, production technologists and well engineers to develop exploration, appraisal, development and production strategies.
• Keep up to date with well and reservoir evaluation techniques, tools and software.
• Ensure physical (log prints and digital) database updates.
• Prepare technical reports and presentations summarising petrophysical results and recommendations for management, regulators and other stakeholders.
• Skilled in GeoGraphix software.

Accountabilities

• Contribute to cost-effective core and log data acquisition, analysis and evaluation as part of the Geosciences team.
• Evaluate tubular integrity and zonal isolation for well completions, and recommend remedial cement squeezes where necessary.
• Advise on perforation and completion intervals for optimal reservoir production.
• Deliver quality petrophysical work for field development, drilling, completion and workover activities.
• Contribute to quality delivery of hydrocarbon maturation, resource volume estimation, classification, reporting and assurance.
• Implement well and reservoir management activities that safeguard or optimise asset production potential and long-term ultimate recovery.
• Deliver integrated work with all disciplines and stakeholders, including Wells Engineering, Reservoir Engineering, Production Technologies, partners and regulators.
• Apply appropriate technologies to prepare geosciences inputs for exploration, appraisal, development, well planning and drilling.
• Carry out geosciences operations and well-site duties during drilling and workover programmes, reservoir surveillance and production optimisation follow-up.
• Deliver pore pressure and fracture gradient prognosis and real-time monitoring for new wells and all well re-entries.

General skills and requirements

• A strong track record of integrated delivery and the ability to build a shared vision.
• Experience in integrated reservoir modelling and communicating uncertainty and subsurface risk.
• Experience in drilling and data-acquisition operations.
• Experience contributing to field development plans and field studies, with an appreciation of how studies shape development and business decisions.
• A commercial, value-creation mindset, with drive for cross-functional integration and risk management.
• Willingness to step outside discipline silos to deliver integrated products.
• Experience in tight reservoir evaluation.
• Strong data management and digitalisation skills.
• A track record of outside-the-box thinking.
• Strong interpersonal and communication skills.
• A strong team player and team builder, with Enterprise-first behaviours and a champion of working together.
• Experience in QI / AVO is an advantage.
• A high degree of professionalism and a drive for excellence and continuous improvement.

Qualifications

• University degree in numerical sciences, electrical engineering or geosciences, with more than 10 years of experience in the upstream oil and gas industry, onshore and offshore. A master's degree (MSc) is an advantage.
• Strong technical background and competence in geosciences, risk and uncertainty management, field development and execution, and well and reservoir management.
• Proficiency in geoscience technical, computing and productivity tools.
• A natural integrator who works effectively in large, diverse multidisciplinary teams, with good stakeholder management for interfaces with partners and regulators.
