Geological Consultant

Job Overview:

Onesubsea seeks a skilled Geologist to interpret geological and geophysical data, build subsurface models, and support exploration and development activities. This role demands expertise in sequence stratigraphy, reservoir characterization, and multi-disciplinary integration.

Key Responsibilities:

1. Subsurface Modeling:
   • Construct detailed geological models using well logs, core samples, and seismic data.
   • Identify and evaluate hydrocarbon potential through analysis of reservoir properties.
   • Conduct basin analysis to assess petroleum systems and hydrocarbon prospectivity.
2. Exploration and Prospect Evaluation:
   • Assess exploration prospects using integrated geological and geophysical data.
   • Develop risk assessments and volumetric estimates for exploration opportunities.
   • Recommend drillable locations by integrating subsurface data with operational considerations.
3. Reservoir Characterization:
   • Collaborate with reservoir engineers to optimize field development strategies.
   • Contribute to well placement, trajectory planning, and drilling program design.
   • Support production forecasting by updating geological models with new data.
4. Sequence Stratigraphy:
   • Apply sequence stratigraphic principles to identify depositional environments and stratigraphic patterns.
   • Differentiate transgressive, regressive, and lowstand deposits to predict reservoir, seal, and source rock distributions.
   • Map depositional sequences and unconformities using seismic and sequence stratigraphic analyses.
5. Technical Expertise:
   • Utilize software such as Petrel for geological modeling and data visualization.
   • Integrate seismic reflectors, parasequences, and other data to enhance 3D reservoir models.
6. Collaboration and Cross-Disciplinary Work:
   • Work closely with geophysicists, petrophysicists, and reservoir engineers to achieve project goals.
   • Ensure alignment of geological models with reservoir performance and production strategies.
