Company: PTTEP Energy Development Company Limited
Geologist
Job Purpose
Geologist participates in correlating various kinds of technical data by coordinating with other subsurface discipline (geophysicists and reservoir engineers) with objectives to create maps and models to analyse reservoir geological distributions characteristics of assigned areas as well as prepare and execute delineation/ development drilling activities with drilling engineers for PTTEP ED.
Key Accountabilities
- Ensure geological and petroleum system study integration to get best of resource evaluation and delineation, development well and platform locations.
- Provide geological and subsurface uncertainty input to field development plan in coordination with reservoir engineer and other related parties.
- Evaluate and integrate the data of subsurface (logs, cores, seismic), reservoir and production to perform reservoir characterization analysis and resources assessment to identify new development and infill opportunities in mature fields and support production optimization.
- Perform annual resources and reserve assessment.
- Prepare and execute delineation/ development drilling activities including preparation of delineation, development work program, well proposal, monitoring drilling operations, and post well evaluation to be in line with studies and programs.
- Evaluate horizontal well opportunity by detailed reservoir analysis e.g. tank correlation, reservoir pressure & connectivity, 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
- 5+ years of experience in E&P Business related to 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.
