GEOPHYSICIST (Oil & Gas Only)

Pengiklan Anonim; Jakarta Utara; On-site; IDR 600,000,000 - 1,200,000,000; Full time

Job summary

Pengiklan Anonim is seeking a senior geophysicist to lead detailed seismic interpretation for field development and well planning in Indonesia. The role focuses on integrating seismic data with geological and reservoir data to guide FDPs and infill drilling strategies.

Candidates should bring 15+ years of oil and gas experience, strong 2D/3D seismic skills, and a track record in development geology and uncertainty assessment to support mature-field opportunities and reserves planning.

Qualifications

• Bachelor's degree or higher in Geophysics, Geoscience, Geology or related discipline.
• Minimum 15 years of oil & gas industry experience with seismic interpretation and development geophysics.
• Strong hands-on experience interpreting 2D and 3D seismic data in producing oil and gas fields.
• Demonstrated experience in structural interpretation, fault mapping, horizon interpretation, depth conversion, and seismic-to-well integration.

Responsibilities

• Perform detailed interpretation of 2D and 3D seismic data to support field development, reservoir characterization, and well planning.
• Develop and maintain structural interpretations, including horizon and fault interpretation, structural frameworks, depth maps, and reservoir compartmentalization.
• Integrate seismic interpretation with well logs, geological, petrophysical, pressure, production, and reservoir engineering data.
• Perform and/or supervise seismic-to-well ties, synthetic seismograms, velocity analysis, time-depth conversion, and depth mapping.
• Identify and characterize faults, structural closures, reservoir boundaries, and potential reservoir compartments affecting field development and production.
• Support identification and maturation of new well, infill drilling, sidetrack, and redevelopment opportunities.
• Provide geophysical input to well placement, target selection, well trajectory planning, and geological prognosis.
• Assess seismic uncertainty and communicate its impact on well placement, reserves/resources, reservoir connectivity, and development decisions.
• Conduct seismic attribute analysis and other advanced interpretation techniques where appropriate to improve reservoir characterization.
• Review seismic data quality and identify requirements for seismic reprocessing, acquisition, or other geophysical studies.

Job description

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

Minimum 15 years of relevant oil and gas industry experience, with substantial experience in seismic interpretation and development geophysics.

Strong hands-on experience interpreting 2D and 3D seismic data in producing oil and gas fields.

Demonstrated experience in structural interpretation, fault mapping, horizon interpretation, depth conversion, and seismic-to-well integration.

Experience supporting development drilling, infill wells, sidetracks, and field redevelopment projects.

Strong understanding of seismic acquisition and processing principles and their impact on interpretation.

Experience working with seismic reprocessing projects and interaction with seismic processing contractors is preferred.

Experience with seismic attributes and quantitative interpretation techniques is highly desirable.

Experience supporting FDP/POD, reserves assessment, annual work programs, or similar field development activities.

Strong understanding of subsurface uncertainty and its impact on well placement and field development decisions.

Experience with mature-field redevelopment would be a strong advantage.

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

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

Conduct seismic attribute analysis and other advanced interpretation techniques where appropriate to improve reservoir characterization.

Evaluate the potential application of seismic inversion, AVO, rock physics, spectral decomposition, and other quantitative interpretation techniques where technically justified.

Review seismic data quality and identify requirements for seismic reprocessing, acquisition, or other geophysical studies.

Prepare technical scopes of work for seismic processing, reprocessing, inversion, and special geophysical studies and provide technical oversight of contractors.

Perform quality control of seismic processing and reprocessing results and ensure that final products are suitable for interpretation and development purposes.

Work closely with geologists to ensure consistency between seismic interpretation, structural frameworks, stratigraphic interpretation, and static geological models.

Work with reservoir engineers to ensure geophysical interpretations and uncertainties are appropriately incorporated into dynamic reservoir models and development scenarios.

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

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

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

Provide technical guidance and mentoring to junior and mid-level geoscientists.
