Job Purpose

Geophysicist Calibrates and integrates seismic data with other technical information to conduct detailed seismic interpretation and reservoir mapping in assigned areas, contributing to the identification of optimal well locations. Collaborates with the Development team in preparing well proposals, designing multi-target wells, supporting drilling operations, and conducting post-well evaluations for PTTEP ED.

Key Accountabilities

• Analyse all technical data, including detailed seismic interpretation and mapping, to identify optimal delineation, development well, and platform locations.
• Integrate geological studies to enhance understanding of the geological framework in the development area, sup-porting resource assessment and identifying the best locations for delineation, development wells, and platforms.
• Provide geological and subsurface uncertainty input for the field development plan, in collaboration with reservoir engineers and other relevant stakeholders.
• Prepare and manage delineation and development drilling activities, including the creation of work programs, well proposals, monitoring drilling operations, and conducting post-well evaluations to ensure alignment with studies and project goals.
• Evaluate horizontal well opportunity by detailed reservoir analysis e.g. tank correlation, reservoir pressure & con-nectivity, sand mapping, reservoir characterization, HCIP estimation & economic analysis, Horizontal well planning & targeting, pre-job modelling.
• Execute horizontal well operations including preparation phase, drilling operations monitoring, and post-drilled evaluation / HCIP & reserves booking.

Professional Knowledge & Experiences

• Bachelor’s degree or higher in Geosciences or a related field.
• 5+ years of experience in the E&P business, with a focus on subsurface tools and technologies.
• Strong understanding of the Gulf of Thailand (GOT) petroleum system, and familiarity with the well factory concept and related processes.
• Extensive experience in development well planning and targeting, monitoring and execution (deviated/horizontal wells) within the GOT.
• Experience in reservoir management and EOR is a plus
• Experience working in Block G1/61 (Erawan, Platong, Satun and Funan) is an advantage.
• Proficiency in subsurface software (e.g., Petrel, DSG) and related systems.
• Excellent communication and interpersonal skills, with the ability to collaborate across multidisciplinary teams.
• Good project management skill is required.
• Fluency in both written and spoken English, with strong technical writing and presentation skills.
