Production Geologist - HLP | Heritage Energy Operational Services Limited (HEOSL)

Department: Development & Exploration

Location: Lagos

Job Summary

This HLP role provides hands-on exposure to subsurface mapping, well correlation, and field development activities, aimed at developing the candidate into a competent production geologist. Working within a multidisciplinary team, the candidate will support reservoir characterization and contribute to maximizing recovery from OML-30’s mature assets. The successful candidate will join a competent team of geoscientists responsible for subsurface interpretation, to maximize the value of our oil and gas assets to both enhance hydrocarbon production and optimize field development (plans). He/she will mainly work in the Subsurface team and with the Petroleum Engineering Functions to address technical deliverables as assigned by the team leadership.

Key Accountabilities

• Assist in generating structural and stratigraphic maps to support reservoir models and development plans.
• Integrate well logs, core data, and seismic interpretations to define reservoir architecture.
• Participate in well planning, including geological prognosis and real-time monitoring during drilling.
• Collaborate with reservoir engineers and petrophysicists to support volumetric estimation and recovery factor evaluations.
• Monitor production trends in relation to geological heterogeneity and reservoir continuity.
• Maintain and update geologic databases and subsurface models using industry-standard software (e.g., Petrel, Kingdom).
• Support the preparation of field development plans and reserves reviews.
• Ensure data management practices comply with regulatory and HSE standards.

Skills and Competences

• Reservoir and structural geology interpretation
• Well log correlation and facies analysis
• Basic seismic interpretation and fault mapping
• Volumetric calculations and reservoir partitioning
• Knowledge of well planning and geosteering support
• Proficiency in Petrel, Techlog, or similar software
• Familiarity with production geoscience workflows

Qualification

• B.Sc. at 2nd Class upper division in Geology, Geophysics, or Geosciences or related field from an accredited university. M. Sc. is an advantage
• Mandatory NYSC discharge certificate
• 3 – 5 years of relevant work experience (including internship & NYSC in the Oil & Gas sector is advantageous).
• Strong analytical and communication skills, with attention to detail and safety-conscious mindset.
• Willingness to travel to remote field locations within the Niger Delta for hands on drilling related activities.
