Senior Geophysicist

We’re hiring a Senior Geophysicist to lead seismic exploration and interpretation for Ad Terra’s regional office in Kuala Lumpur — from data collection and processing through to the geophysical interpretations that shape drilling and development decisions across the portfolio. We’re looking for deep command of the seismic toolkit and the judgment that comes from years of hands-on interpretation, paired with real versatility: someone who tracks new methods and technologies as closely as they apply proven ones, and who’s ready to help build the AI-assisted seismic workflows that will define how the discipline works next.

What You'll Do

Data acquisition:

Design data acquisition plans

Define suitable seismic measurements methods

Adapt data collection methods

Data processing:

Process seismic data

Define suitable seismic measurements and data-processing methods

Load, gather, transfer, and organize seismic data

Conduct quality control of data

Data interpretation:

Conduct geophysical interpretations

Build and test 3D models

Map 3D seismic data models

Make structural interpretation and mapping

Run forecasts

Resolve interpretation issues

AI & Digital Tools:

Apply and help develop AI/ML-assisted seismic interpretation workflows, including automated fault and horizon picking, denoising, and facies classification

Evaluate and pilot emerging AI tools to improve seismic processing and interpretation efficiency

Contribute geophysical domain expertise to Ad Terra's digital subsurface intelligence initiatives

Projects:

Complete tasks in areas of expertise

Document progress, setbacks, and new processes

Establish clear and relevant timesheets

Reporting:

Generate and write reports, create maps, tables, figures, and summaries

Review documents, studies, models, and reports prepared by peers

Report results to managers, clients, partners, etc.

What You'll Bring

University degree (MSc or PhD) in Geology, Geophysics, or a related field

Experience as a Geoscientist (8-12 years)

Minimum 8–12 years of hands-on Oil & Gas industry experience (exploration, development, or production) — mandatory

Insight into rock physics, AVO, Inversion process

Intermediate knowledge of Matlab or Python coding and Bash / shell scripting

Comfortable working with and developing AI/ML tools (e.g., automated picking, ML-assisted denoising or interpretation) to improve processing and interpretation efficiency

Knowledge of seismic processing software such as Seismic Unix / Madagascar / Promax / SeisSpace / Omega / OpendTect / RadExPro / Reveal / Petrel

Experience in 2D/3D seismic interpretation

Experience with Velocity Modelling

Good understanding of the oil and gas industry

Familiarity with PETRONAS Technical Standards (PTS) and the Malaysian upstream regulatory framework is an advantage; professional body registration a plus

Excellent communication and presentation skills

Strong numerical and literacy skills

Systematic and methodical approach

Able to work efficiently under pressure

Rigor and organization

Proficient with Microsoft Office Suite

Fluent in English (excellent verbal and written proficiency)
