Job description

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)
