Senior Geologist at Ad Terra — CAN | Base Career

We’re hiring a Senior Geologist to anchor Ad Terra’s geological consulting and modeling capability from our Kuala Lumpur office.

This isn’t a single-asset wellsite posting — it’s a portfolio-level seat spanning Ad Terra’s international multi-resource projects (oil & gas, geothermal, critical elements).

You’ll act as technical consultant and modeler across our clients and OpCos, and coordinate geological inputs with the Geophysics, Petrophysics, and Reservoir Engineering teams.

It’s one of the most cross-cutting technical seats in the group, with direct visibility into how Ad Terra’s projects are evaluated, modeled, and matured.

We’re looking for deep geological judgment built over years in the field, paired with real versatility — someone as curious about where the discipline is heading as they are skilled in how it’s practiced today, ready to help build and adopt the AI-assisted tools that will shape how geology gets done next.

Provide geological consultancy and technical assurance across Ad Terra’s OpCos (45-8 Energy, LiCAN Resources, SGE) and external client or partner engagements
Act as technical reference on stratigraphy, structural geology, and reservoir characterization for exploration and development projects
Support technical due diligence on new assets, farm-ins, and licence opportunities across the portfolio

Compile, QC, and integrate lithological, petrographic, and biostratigraphic data into static geological models
Build, maintain, and update structural and stratigraphic models integrating well and seismic data
Run forecasts and estimate hydrocarbon volumes to support reserves and resources reporting
Populate and maintain geological databases

Apply and help develop AI/ML-assisted workflows for geological modeling, facies classification, and automated core or log interpretation
Evaluate and pilot emerging AI tools (e.g., LLM-assisted technical reporting, computer-vision core and image analysis) for adoption across the geoscience team
Contribute geological domain expertise to Ad Terra's digital subsurface intelligence initiatives

Coordinate geological inputs with the Geophysics, Petrophysics, and Reservoir Engineering teams to keep models and interpretations consistent
Liaise with JV partners, regulators, and external consultants on geological matters
Support prospect and play evaluation, ranking exploration targets across the portfolio

Provide geological look-ahead and formation-top predictions to support live drilling operations, remotely from the KL office
Review wellsite geology reports (cuttings, cores, mudlogs) submitted by field teams and validate against the pre-drill geological model
Recommend casing points, coring intervals, and total-depth calls based on remote data review, in coordination with on-site operations teams
Conduct quality control of geological data and interpretations

Complete tasks in areas of expertise
Document progress, setbacks, and new processes
Establish clear and relevant timesheets

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.

University degree (MSc or PhD) in Geology, Geophysics, or a related field
Minimum 8–12 years of hands-on Oil & Gas industry experience (exploration, development, or production) — mandatory
In-depth knowledge of geological principles and practices, namely sequence stratigraphy and application to facies prediction
Proficient with geological programs such as Petrel, Geolog, Techlog, etc.
Comfortable working with and developing AI tools (e.g., Python scripting, LLM-based workflows, ML-assisted classification) to support and automate geological interpretation
Experience with basin modelling and petroleum systems analysis
Experience providing geological consultancy or technical advisory services, ideally across multiple assets, operators, or clients
Understanding of PETRONAS project lifecycle stages and JV / PSC operating models
Familiarity with PETRONAS Technical Standards (PTS) and the Malaysian upstream regulatory framework is an advantage; professional body registration (e.g., relevant geoscience/engineering body) a plus
Comfortable operating remotely from a base office — providing operational geological support without requiring permanent wellsite presence
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)

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)

Thank you for considering joining our team.

We look forward to reviewing your application!
