KEY OBJECTIVES - Build and evaluate a range of 3D static geological models in support of reservoir characterization and dynamic reservoir simulation studies, leading to an understanding of the reserves distribution and an optimum field development strategy for the development projects.
- Principal role to build discrete static models utilizing multiple subsurface scenarios capturing structural, stratigraphic and petrophysical uncertainties, for reserves assessment, history matching, production optimization and development strategy. This requires experience in geomodelling using seismic data to help constrain geological model facies and knowledge of analogue data to constrain property distributions within the modeled facies.
- Review near field exploration and appraisal opportunities which may prove to be economic as part of a larger development.
- Prepare detailed reports on model construction and support the reporting of hydrocarbons-in-place calculations as well as update and prepare field development plans.
- Assist team review of potential appraisal and development well locations and trajectories, and preparing well proposals
PRINCIPAL ACCOUNTABILITIES - Establish reservoir characterization of the Malaysia oil and gas fields that incorporates sufficient facies analysis, sedimentology, sequence stratigraphy and dynamic data (reservoir pressure, well deliverability) that meet both project objectives and milestones.
- Provide technically accurate and geologically sound reservoir descriptions for Oil and Gas Fields that incorporate sufficient detail to meet COMPANY and JV Partners' requirements
- Independently perform geological modelling (several projects and in complex geological and structural setting) by using the industry software (preferred Petrel), starting from designing what to be modelled, input data checking and preparation for structural framework, 3D grid design, well data analysis and re-scaling, facies and petrophysical modelling, volumetric analysis etc.
- Calibrate static models with dynamic production data where possible (in association with reservoir engineers and G&G specialists).
- Conduct resource assessments to SPE/PETRONAS guidelines for all oil and gas fields and provide technical inputs into ARPR submissions.
- Study the subsurface uncertainties by building multiple scenarios (as well as stochastic realizations) to quantify volumetric
- Perform geological risk analysis in sufficient subsurface data, and provide suggestion and advise as per the outcome of the analysis
- Provide geological input to drilling programs for appraisal and development wells (geological cross sections, maps, correlations and facies models).
- Optimize appraisal/development well locations in conjunction with the geophysicist(s) and reservoir engineer(s) using Petrel as the common work platform.
- Prepare and present technical data to partners during all stages of project evaluation, well proposals, Field Development Plan's and project implementations, to achieve endorsements and approvals for proposed work activities.
- Work closely with drilling engineers, operations geologists, petrophysicists and reservoir engineers on all aspects of well planning and implementation.
