Geologist

Job Title: Wellsite Geologist

Job Description

The Wellsite Geologist is responsible for interpreting and integrating geological data to provide geological support for drilling operations and field development activities. This role supports well planning, geosteering, formation evaluation, geological monitoring, and data acquisition throughout the drilling process. The Wellsite Geologist works closely with drilling, reservoir, geoscience, and operations teams to optimize well placement, ensure data quality, and support reservoir characterization efforts.

In addition to providing technical expertise, the Wellsite Geologist oversees geological service providers, ensures the accuracy of geological reporting, and contributes to field development planning and reservoir studies. The role may also involve mentoring junior geoscience personnel and supporting continuous improvement initiatives.

Responsibilities

Geological Operations Support

• Interpret geological, petrophysical, and drilling data to support safe and efficient well execution.
• Provide real-time geological monitoring and formation evaluation during drilling operations.
• Support horizontal and directional well placement through geosteering and geological interpretation.
• Generate and maintain geological cross-sections, maps, formation evaluation logs, and other subsurface deliverables.
• Prepare and distribute final well reports and post-drill geological evaluations.
• Support reservoir characterization, field development planning, and multidisciplinary subsurface studies.

Wellsite Geological Services Management

• Supervise and coordinate geological service providers and wellsite geological operations.
• Monitor and oversee geological data acquisition activities, including:
• Mud logging operations
• Logging While Drilling (LWD) services
• Wireline logging operations
• Coring and sample acquisition programs
• Ensure quality assurance and quality control of geological data, reports, and interpretations.
• Audit geological services and data acquisition activities when required.
• Serve as the primary technical contact for geological service providers and contractors.
• Review, validate, and manage geological deliverables and supporting documentation.

Planning and Coordination

• Participate in pre-drill planning activities and operational readiness reviews.
• Coordinate geological data acquisition programs and ensure alignment with project objectives.
• Communicate geological findings and operational updates to stakeholders through meetings, reports, and presentations.
• Coordinate the collection, shipment, storage, and documentation of geological samples, cores, and related materials.
• Support special studies, technical projects, and post-drill evaluations.

Pressure Monitoring and Reporting

• Monitor geological indicators related to formation pressure and drilling hazards.
• Support abnormal pressure surveillance activities through data analysis and interpretation.
• Maintain pressure evaluation records and communicate findings to drilling and operations teams.
• Prepare detailed reports documenting observations, interpretations, and operational recommendations.

Leadership and Development

• Mentor and support the development of junior geologists and geological personnel.
• Promote best practices in geological operations, data management, and reporting.
• Contribute to continuous improvement initiatives that enhance operational performance and data quality.
