Purpose and Scope
• Act as the designated Geoscience Manager for assigned Site Characterization projects.
• Deliver the geoscience scope in accordance with agreed quality, schedule, budget and client requirements.
• Coordinate geoscientists, specialists and subcontractors to achieve project objectives.
• Manage project risks, assumptions, interfaces, dependencies and technical decisions within the geoscience workstream.
• Provide technical management and mentoring of junior geoscientist colleagues.
• Manage interfaces with other TGS departments throughout project execution.
• Support bids, client engagement and continuous improvement of department standards and processes.
Key Responsibilities
Project Geoscience Management
• Own the geoscience workstream from conception through delivery and closeout in accordance with the TGS project framework.
• Maintain the geoscience delivery plan, including schedules, activities, resources, quality review points and deliverable dates.
• Coordinate priorities and task allocation for the project geoscience team, monitoring progress and addressing delivery constraints.
• Manage geoscience scope, assumptions, technical queries, risks, changes and decisions, ensuring records remain current and trackable.
• Provide accurate reporting on progress and forecasts to the Project Owner.
• Provide technical management and mentoring of junior geoscientist colleagues.
• Manage interfaces and dependencies with Acquisition, Imaging, Geotechnical and other TGS departments to support efficient project delivery.
• Ensure subcontractor and cross-disciplinary inputs are received, reviewed and integrated at the appropriate stage.
Data Interpretation and Integrated Assessment
• Create and manage ground model projects using industry-standard software and robust data management practices.
• Perform and supervise seismo-stratigraphic and geohazards interpretation, including point diffractor interpretation and shallow-gas assessment.
• Integrate geological, geophysical and geotechnical data into coherent UHR3D ground models and project interpretations.
• Undertake interpretation using relevant PSTM, PSDM, velocity 3D volumes.
• Work closely with Imaging and the Integrated Sensor Specialist to detect & resolve data-quality issues and maintain consistency across outputs.
• Apply agreed methodologies, project specifications, industry guidance and best practice throughout interpretation.
Reporting, Deliverables and Client Interface
• Lead preparation of integrated UHR3D interpretation reports and geoscience deliverables, combining sub-surface ground model assessment with integrated sensors interpretation.
• Ensure deliverables are complete, internally consistent and quality-checked, technically defensible and issued in line with the approved programme.
• Lead geoscience progress calls and technical discussions with clients, clearly explaining methods, findings, uncertainties, risks and proposed actions.
• Coordinate responses to review comments and ensure agreed actions are closed or formally resolved.
• Support the Project Owner with scope clarification, geoscience activities and deliverables schedule, change management and communication of delivery impacts.
Quality and Continuous Improvement
• Apply the TGS Quality Management System and project-specific quality plan to geoscience activities and deliverables.
• Plan and coordinate checking, review and approval activities, ensuring suitable and timely closeout of comments.
• Lead the geoscience contribution to project closeout, capturing lessons learned and recommending continuous improvement actions.
Bids and Technical Development
• Contribute technical content, delivery assumptions, resource estimates and schedule inputs to proposals and bids.
• Support client workshops, presentations and technical marketing.
• Aid the development of the Site Characterization Geoscience functional area through supporting continuous improvement of standards, best practices and technical strategy priorities.
