Wellsite Geologist

Wellsite Geologist
The Wellsite Geologist plays a critical role in ensuring the safe and efficient execution of geological operations during drilling activities. Responsibilities include, but are not limited to:
Responsibilities
Operational Coordination

• Serve as the primary point of contact between the office-based Operations Geologist, NWS team, and offshore personnel.
• Review and familiarize with all relevant wellsite reference data, including subsurface technical packages, offset well logs, maps, and operational challenges (provided by Ops Geologist prior to well start-up).

Geological Oversight

• Ensure cuttings samples are collected and described in accordance with the Geological Operations Plan, providing detailed interpretative descriptions.
• Provide geological interpretation of mud logs to support operational decisions and at total depth.
• Advise on potential geological hazards and support root cause analysis for Non-Productive Time (NPT) events.

Data Acquisition & Quality Control

• Coordinate data acquisition from service providers (LWD, wireline logging, mud logging, coring).
• Communicate program revisions and ensure timely updates to service crews.
• Advise MWD, mud logging personnel, and directional drillers on subsurface data and program requirements.
• Maintain quality control of all subsurface data and geological operations.

Team Leadership & Communication

• Act as liaison between the Wellsite Leader and mudlogging crew, ensuring alignment on key geological and operational issues.
• Mentor and coach CLIENT’s badge geologists in wellsite activities.
• Maintain regular communication with the Wellsite Leader, Driller, and Ops Geologist to share observations and manage geological risks.

Compliance & Offshore Readiness

• Ensure adherence to CLIENT’s policies, Code of Conduct, and values.
• Meet all HSSE offshore readiness requirements, including certifications: TWIC, HUET, LTGO, Work VISA, Letter of Determination, and logistics registration.
• Ensure conformance to CLIENT’s Group Practices for pore pressure detection.

Qualifications
Minimum qualifications and competencies:

• Bachelor’s degree in Geology or related field.
• 10–20 years of experience as a Wellsite Geologist (preferred).
• Offshore exploration experience, particularly in the Trinidad Columbus Basin (minimum 3 years).
• Flexible work schedule aligned with drilling activity.
• Proven track record of safe behavior and active participation in rig safety programs.
• Strong communication and interpersonal skills essential for safe and successful well execution.

Deliverables & Meetings
Offshore

• Attend daily morning calls, tour meetings, hole section previews, and pre-spud meetings.
• Participate in handover meetings with Wellsite Geologist counterparts.
• Liaise regularly with Wellsite Leader and Driller to communicate geological risks.

Onshore

• Maintain regular contact with Operations Geologist to share observations and updates.

Documentation & Reporting

• Keep the well data book current throughout drilling operations.
• Compile draft geological operations summaries after each hole section for the End of Well Report (EOWR), including:
• Rock sample descriptions
• Hydrocarbon shows
• Anomalous events
• Review and document lessons learned after each hole section.
• Maintain geology and engineering files.
• Expedite final logs and data.
• Correlate well data to support casing point, core point, and total depth decisions.
