Main Purpose:

To support seismic reservoir characterization and interpretation within integrated reservoir studies and well planning efforts. The role focuses on applying geophysical principles and learning industry-standard seismic data analysis techniques to enhance subsurface understanding, under the guidance of experienced professionals.

Key Responsibilities:

Seismic Reservoir Characterization & Inversion Support

• Assist in generating basic seismic inversion products and attribute maps under supervision.
• Support rock physics modeling and perform fluid/lithology substitution studies.
• Help prepare synthetic seismograms (zero-offset and offset) for seismic ties.
• Contribute to wavelet extraction and well-to-seismic tie analyses.
• Participate in seismic attribute analysis (crossplots, elastic impedance, AVO) for fluid and lithology characterization.
• Learn and apply various seismic inversion techniques (e.g., post-stack, pre-stack, colored inversion).
• Support basic risk and uncertainty assessments in reservoir characterization studies.

Seismic Interpretation & Integration

• Assist in seismic interpretation by identifying key horizons and fault structures.
• Generate synthetic seismograms and carry out well-to-seismic ties under guidance.
• Support map generation for structural and stratigraphic analysis.
• Collaborate with geologists, petrophysicists, and reservoir engineers to integrate geoscientific data.
• Learn and contribute to velocity modeling for depth conversion and volumetric estimation.
• Participate in quality control (QC) of seismic acquisition and processing projects.

Well Planning & Placement

• Support well planning activities for appraisal, development, and infill drilling.
• Use seismic attribute volumes to evaluate well targets and plan trajectories.
• Assist in identifying shallow hazards and overburden characterization for safe well placement.
• Provide preliminary geophysical inputs to drilling and operational teams.

Project Support & Development Planning

• Contribute to technical inputs for Declaration of Commerciality (DoC), Appraisal Plans, and Field Development Plans (FDP).
• Support seismic-based analysis of sandbody connectivity and reservoir continuity.
• Participate in cross-functional evaluations to assess resource potential and development options.

Stakeholder Interaction & Knowledge Sharing

• Prepare documentation, basic technical reports, and internal presentations.
• Engage in knowledge-sharing sessions, safety briefings, and collaborative discussions.
• Ensure compliance with Health, Safety & Environment (HSE) standards and PSC/JOA guidelines.

Core Technical Competencies:

• Foundational knowledge in key geophysical domains:
• Seismic interpretation and inversion
• Rock physics modeling and fluid substitution
• Synthetic seismogram generation and seismic ties
• AVO analysis and seismic attribute interpretation
• Familiarity (academic or professional) with geophysical software is preferred:
• Petrel, Hampson-Russell, Jason, RockDoc, Landmark, etc.

Desirable Skills:

• Exposure to programming (Python, MATLAB, C) and interest in data science or machine learning.
• Understanding of risk and uncertainty assessment in geophysical studies.

Qualification:

• Master’s degree in Geophysics from a recognized institution

Experience:

• 1–3 years of experience in oil & gas exploration and production.
• Relevant internship or project experience in seismic interpretation, inversion, or reservoir studies is a strong advantage.
