GEOLOGIST (Oil & Gas Only)

Pengiklan Anonim; Jakarta Utara; On-site; IDR 1,232,177,000 - 2,112,304,000; Full time

Job summary

Pengiklan Anonim is looking for a senior geologist with a minimum of 15 years in oil and gas, focused on development and production geology. A geology degree is required, and Indonesian asset experience is a strong advantage.

You will lead integrated geological evaluations using well, log, seismic, and production data, develop reservoir models, and support field development planning and post-well analysis.

Qualifications

• Bachelor’s degree or higher in Geology, Geological Sciences, Geoscience, or a closely related discipline.
• Minimum 15 years of oil and gas experience in development/production geology.
• Strong experience with producing fields and field development projects.
• Experience supporting drilling operations and post-well evaluation.
• Experience with FDP/POD, reserves assessments, and annual work programs.
• Mature-field redevelopment and production optimization experience preferred.
• Indonesia asset and regulatory/PSC environment experience a strong plus.

Responsibilities

• Perform integrated geological evaluation of producing oil and gas fields using well, log, seismic, production, and pressure data.
• Develop and maintain understanding of reservoir structure, stratigraphy, depositional environment, facies, and reservoir quality.
• Build, update, and quality-control geological frameworks and static reservoir models for development decisions.
• Perform well correlation, structural interpretation, reservoir mapping, thickness mapping, and volumetric assessment.
• Integrate geological interpretation with reservoir engineering and production data to identify potential development opportunities.
• Generate new well, infill drilling, sidetrack, recompletion, and workover opportunities with geological justification.
• Provide geological support during drilling operations and participate in real-time well evaluation and geosteering as required.
• Prepare FDP, POD, reserves/resource evaluations, and subsurface development strategies with clear documentation.

Job description

Bachelor's degree or higher in Geology, Geological Sciences, Geoscience, or a closely related discipline.

Minimum 15 years of relevant oil and gas industry experience, with substantial experience in development and/or production geology.

Strong experience working with producing fields and field development projects.

Demonstrated experience in well planning, well correlation, structural and stratigraphic interpretation, reservoir mapping, and geological modeling.

Experience identifying and maturing development drilling, infill, sidetrack, recompletion, and workover opportunities.

Strong understanding of reservoir characterization and integration of geological, petrophysical, production, pressure, and reservoir engineering information.

Experience supporting drilling operations and conducting post-well evaluation.

Experience contributing to FOP/POD, reserves assessment, annual work programs, or similar field development activities.

Experience with mature-field redevelopment and production optimization is strongly preferred.

Experience with both elastic and carbonate reservoirs would be an advantage.

Experience with Indonesian oil and gas assets and the Indonesian regulatory/PSC environment would be a strong advantage.

Job Descriptions

Perform integrated geological evaluation of producing oil and gas fields using well, log, seismic, production, pressure, surveillance, and other available subsurface data.

Develop and maintain a detailed understanding of reservoir structure, stratigraphy, depositional environment, facies distribution, reservoir quality, fluid contacts, and compartmentalization.

Build, update, and quality-control geological frameworks and static reservoir models to support development decisions.

Perform well correlation, structural interpretation, reservoir mapping, thickness mapping, property distribution, and volumetric assessment.

Integrate geological interpretation with reservoir engineering and production data to identify remaining hydrocarbon potential and development opportunities.

Generate and mature new well, infill drilling, sidetrack, recompletion, and workover opportunities.

Provide geological justification and risk assessment for proposed development wells and intervention activities.

Participate in well planning, including target definition, well trajectory evaluation, landing-point selection, reservoir penetration strategy, and geological prognosis preparation.

Provide geological support during drilling operations and participate in real-time well evaluation and geosteering activities where required.

Conduct post-well evaluation and integrate drilling results into geological models and future development plans.

Work closely with reservoir engineers to ensure consistency between geological and dynamic reservoir models.

Support preparation and updating of Field Development Plans (FDP), Plan of Development (POD), annual work programs, reserves/resource evaluations, and subsurface development strategies.

Identify subsurface uncertainties and risks and recommend appropriate data acquisition or surveillance programs to reduce uncertainty.

Evaluate historical well performance and subsurface information to identify bypassed or remaining hydrocarbon potential, particularly in mature fields.

Participate in technical reviews, peer reviews, reserves evaluations, and internal assurance processes.

Prepare clear technical reports, maps, presentations, and recommendations for management and other stakeholders.

Provide technical guidance and mentoring to junior and mid-level geologists and contribute to strengthening the overall subsurface capability of the organization.

Work effectively with multidisciplinary teams and external consultants, contractors, partners, and government/regulatory stakeholders when required.
