Geophysicist

PTTEP Services Limited

Job Purpose

Geophysicist (GSC/S) is responsible for the execution of technical workflows, QA/QC, supervision of junior staff and project management.

Key Accountabilities

• Carrying out seismic data processing project work, identifying and solving moderate geophysical problems independently, and working with Project Leader for complex geophysical problems.
• Developing and optimizing some processing steps in projects, managing, preparing and ensuring quality control of geosciences data to support team projects.
• Performing time processing and depth imaging of 2D and 3D land and marine seismic data (including generation of processing flows, parameter testing, velocity interpretation and model building).
• Preparing, running, and managing production migration, tomography and other processing workflows on the company computer system and resolving any issues that may arise during production run.
• Ensuring quality of seismic products deliver to clients is good quality and preparing project reports and presentations, and participating in project meetings
• Communicating with asset team and geophysicist on project matters, supervising other processing/depth imaging staff to complete their project work and assisting the team leader to manage team projects
• Reporting to Project Leader or above and perform other related tasks as assigned by the team leader/project leader
• Supervising and QC all out-house seismic processing projects
• Guiding junior processing geophysicists, evaluate new algorithmic updates or software modules, and streamline production workflows.
