Geoscientist III

Geoscientist III

Location: Lagos

Employment Type: Contract

Overall Purpose of the Job

• Responsible for integrating geological, geophysical, petrophysical, reservoir and production data to develop robust predictive subsurface models that support field development, reservoir management, production optimisation and reserves maturation.
• The role identifies and matures development and production opportunities, provides geological assurance throughout the well-delivery process, and applies appropriate technologies and uncertainty-management techniques to improve reservoir understanding, optimize hydrocarbon recovery and reduce subsurface and drilling risks.
• The role supports the maturation and delivery of development and production opportunities across assigned assets and contributes to integrated subsurface studies, reservoir-management decisions, well delivery and hydrocarbon reserves growth.
• The Senior Geoscientist operates in a multidisciplinary environment and provides production-geology input to activities undertaken with internal teams, partners and specialist contractors.

Principal Accountabilities

• Develop and maintain integrated geological models incorporating seismic interpretation, well correlations, petrophysical evaluation, reservoir properties and production information.
• Integrate geological and dynamic data to improve understanding of reservoir architecture, connectivity, compartmentalization, fluid distribution and remaining hydrocarbon potential.
• Identify, evaluate and mature development and production opportunities, including infill wells, sidetracks, workovers and other reservoir-management opportunities.
• Provide production-geology input to integrated subsurface studies, Field Development Plans and reservoir-management activities, ensuring delivery to the required technical quality and agreed schedule.
• Lead geological input to development and appraisal well maturation and the Well Delivery Process (WDP), including well objectives, correlations, reservoir targets, depth prognosis, geological uncertainties, drilling risks and data-acquisition requirements.
• Provide geological support during drilling and workover operations, ensuring timely interpretation of new well information and effective management of geological uncertainties and drilling risks.
• Prepare and quality-assure geological inputs to well proposals, well resumes, post-well evaluations and End-of-Well Reports, and incorporate new well results into subsurface models, maps and databases.
• Apply geological risk and uncertainty analysis to subsurface interpretations, volumetric assessments and development decisions.
• Participate in peer, integrated and value-assurance reviews, ensuring geological evaluations and recommendations meet required technical standards.
• Collaborate across Geoscience, Reservoir Engineering, Production Technology, Wells and other disciplines to deliver integrated field-development, reservoir-management and production decisions.
• Coach and mentor less-experienced geoscientists and contribute to technical knowledge sharing, capability development and approved technical publications.

Job Context and Challenges:

• Integrating multidisciplinary datasets of varying quality and resolution into robust geological interpretations and models.
• Predicting reservoir distribution, quality and connectivity away from well control.
• Managing geological uncertainty and its impact on well, production and development decisions.
• Providing timely geological support during drilling, workover and production activities.
• Resolving geological issues affecting field development and production.
• Maintaining alignment between geological models, well information and observed reservoir performance.

Job Knowledge and Qualifications

• Minimum of a B.Sc in Geology or a related geoscience discipline.
• Minimum of 9 years' relevant experience in an operating exploration and production environment.
• Demonstrated competence in production/reservoir geology, geological modelling, reservoir characterization, well correlation and field-development studies.
• Strong understanding of seismic interpretation, petrophysics, reservoir-engineering interfaces and uncertainty management.
• Practical experience in development/appraisal well planning and operational geological support.
• Advanced working knowledge of Petrel or equivalent geological interpretation and modelling software.
• Strong multidisciplinary integration, analytical, technical-writing and presentation skills.
• A Higher Degree or relevant professional qualification is an advantage.
• Candidates must have at least 7 years of experience in the oil and gas industry. Any candidates who apply without this experience will have their CVs rejected immediately.

Relationships:

• Internal - Exploration, Petrophysics, Reservoir Engineering, Production Technology, Drilling & Completions, Engineering, Operations, HSSE and other relevant functions.
• External - Joint Venture partners, relevant regulatory agencies, service companies, consultants and specialist contractors.
