Petrophysicist

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)
