Senior Geophysicist

PTTEP Energy Development Company Limited**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.
