About The Role

This role evaluates the nature and distribution of rock properties and formation fluids across the life cycle of our clients’ reservoirs — from log analysis and core data through to the models that inform reserves and development decisions. We’re looking for rigorous petrophysical judgment paired with real versatility: someone who tracks new interpretation methods and technologies as closely as they apply proven ones, and who’s ready to help bring AI-assisted tools into how petrophysics gets done at Ad Terra.

What You'll Do

Data acquisition

Design well data acquisition plans
Adapt well-log and data collection methods

Data processing

Define suitable well measurements and data-processing methods
Prepare and process well data for petrophysical interpretation
Load, gather, transfer, and organize well data
Conduct quality control of data
Populate and maintain well databases

Data interpretation

Conduct detailed analysis of wireline logs, core data, and seismic attributes
Build and develop petrophysical and geo-mechanical models
Perform volumetric calculations to estimate reserves and resources
Process and interpret borehole imagery
Conduct simulations to model fluid behavior
Develop and improve techniques for formation evaluations from cores and cuttings
Describe log-derived mechanical properties
Characterize conventional and unconventional resources
Resolve interpretation issues
Run forecasts

AI & Digital Tools

Apply and help develop AI/ML-assisted log QC, facies prediction, and automated petrophysical interpretation workflows
Evaluate and pilot emerging AI tools (e.g., automated log correlation, anomaly detection) to improve interpretation efficiency
Contribute petrophysical 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 Geoscience, Petroleum Engineering or a related field
Experience as a Petrophysicist (2-5 years)
Minimum 2–5 years of hands-on Oil & Gas industry experience (exploration, development, or production) — mandatory
In-depth knowledge of petrophysical principles and practices
Proficient with petrophysical programs such as Petrel, Geolog, Techlog, etc.
Comfortable working with and developing AI tools (e.g., Python scripting, ML-assisted log QC or facies prediction) to support and automate petrophysical interpretation
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)

What We Offer

Permanent, full-time local contract with statutory EPF / SOCSO / EIS contributions
Medical and insurance coverage; competitive annual leave
Exposure to international multi-resource projects across Ad Terra's platform (Europe, Canada, Chile, Cyprus, Asia-Pacific)
