Job Purpose

Senior Geophysicist calibrates and integrates seismic data with other technical data to conduct detailed seismic interpretation and mapping of reservoirs in assigned areas, contributing to the identification of optimal well locations. He/She collaborates with the Development team in preparing well proposals, designing multi-target wells, providing drilling support, and conducting post-well evaluations for PTTEP ED.

Key Accountabilities

• Ensure comprehensive analysis of all technical data, including detailed seismic interpretation and mapping, to iden-tify optimal delineation, development well, and platform locations.
• Integrate geological studies to enhance understanding of the geological framework in the development area, sup-porting accurate resource assessment and the identification of the best well and platform locations.
• Provide geological and subsurface uncertainty inputs for the field development plan in collaboration with reservoir engineers and other relevant stakeholders.
• Prepare and oversee delineation and development drilling activities, including the development of work programs, well proposals, monitoring of drilling operations, and post-well evaluations, ensuring alignment with studies and pro-ject objectives.
• 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.
• QA/QC geophysical technical works and perform as leadership role for oil development team.

Professional Knowledge & Experiences

• Bachelor’s degree or higher in Geosciences or a related field.
• 15+ years of experience in the E&P business, specializing in subsurface tools and technologies.
• Strong understanding of the Gulf of Thailand (GOT) petroleum system, with familiarity in the well factory concept and processes.
• Extensive experience in oil and gas reservoir development, including well planning and targeting, monitoring, and execution of deviated and horizontal wells within the GOT.
• Highly require experience in reservoir management and EOR
• Experience working in Block G1/61 (Erawan, Platong, Satun, or Funan) is an advantage.
• Proficient in subsurface software (e.g., Petrel, DSG) and related systems.
• Knowledge of seismic acquisition and processing is a plus.
• Experience in special geophysical studies, such as AVO, is a plus.
• Familiarity with procurement, contract preparation, and evaluation is an advantage.
• Excellent communication and interpersonal skills.
• Good project management skill is required.
• Strong problem-solving abilities and a proactive approach to challenges.
• Ability to mentor and lead teams of geophysicists and other technical professionals.
• Ability to work in a dynamic, fast-paced offshore environment with a focus on delivering results.
• Strong written and verbal communication skills in English.
