Overall Purpose of the Job
The Operations Geologist is key in the planning and execution of oil and gas exploration and drilling projects. Acting as a link between drilling engineers and geoscientists, this role ensures that geological goals align with operational realities. The role involves collaboration across disciplines to enable effective well planning, real-time monitoring, risk mitigation, and precision in offshore or high-pressure drilling environments.
Principal Accountabilities
- Perform Integrated Pore Pressure Prediction (IP3), site surveys, and shallow hazard evaluations for top-hole prognosis, geomechanics, and monitoring.
- Work closely with geoscientists, reservoir engineers, and drilling teams to create accurate geological well prognoses and casing designs aligned with geological targets.
- Evaluate formation data to refine and optimize drilling trajectories.
- Develop comprehensive Geological Programs detailing well objectives, formation evaluation strategies, operational protocols, and sample distribution plans.
- Manage and provide technical/logistical support to wellsite geologists and service partners to collect complete, high-quality geological datasets.
- Compile and disseminate final well reports, logs, and associated documentation promptly.
- Prepare and submit Ready To Drill (RTD) documentation and maintain a complete record of permits and approvals from regulatory bodies.
- Participate in total depth reviews, pre-spud sessions, and after-action reviews, contributing technical insights.
- Oversee all geological services at the wellsite, including mudlogging, wireline logging, and coring operations.
- Ensure compliance with both internal geological objectives and external regulatory standards.
- Maintain ongoing communication with drilling crews, site geologists, and management.
- Support formation evaluation and the Wells team during contracting phases by evaluating technical specs and cost structures for coring, wireline, LWD/MWD, and mudlogging services.
- Prepare data and evaluation plans in line with regulatory obligations.
- Assess technical services related to sample preservation, wellsite geology, and biostratigraphy.
- Provide support for geosteering, casing point selection, coring, wireline logging, and formation testing during drilling operations.

- NYSC discharge or exemption certificate
- Offshore experience, particularly in Jackup Barge/Rig or MODU drilling
- Proficient in pressure prediction, formation evaluation, and shallow hazard assessments
- Familiarity with mud logging, cuttings description, and image log interpretation
- Able to interpret formation evaluation data to identify lithology, fluid types, and borehole conditions
- Experience in directional drilling, depth tracking, and BHA understanding
- Exposure to HPHT environments, managed pressure drilling (MPD), and related challenges
Other Requirements:
- Capable of meeting deadlines and setting priorities under duress
