Development Geologist-00016405

 The Development Geologist will report to the Chief Geologist and lead the development of a Community of Practice for Reservoir Characterization, Geologic Modeling and Development Geology across the corporation. The role will be responsible for 1) improving organizational capability to conduct integrated regional to field-scale geologic evaluations and build fit-for-purpose geological models for hydrocarbon in-place assessment, reservoir simulation studies, field development planning and reservoir surveillance; 2) conduct technical support and review to identify development upside opportunities in existing assets worldwide; and 3) lead peer reviews, knowledge sharing initiatives, and technology transfer across the corporation.

The Development Geologist' responsibilities include but are not limited to:
• Develop regional tectonic, structural and stratigraphic frameworks for core areas focused on major play elements.
• Build, maintain and evaluate large, complex geological models in Petrel modeling software.
• Review depositional facies, conventional core analysis, capillary pressure data, and openhole logs to determine reservoir and non-reservoir rock types & flow characteristics, hydrocarbon distribution and fluid contacts.
• Define optimal reservoir zonation and layering scheme using understanding of sequence stratigraphy and flow unit architecture. Integrate all horizontal and vertical wells accurately into the structural framework and reservoir zonation. Develop workflows and guidelines for standardization of best-practices in structural and stratigraphic model building.
• Perform and QC geostatistical modeling of rock types, porosity, and permeability integrating openhole log, core and 3D seismic data. Develop workflows and guidelines for standardization of best-practices in facies and property modeling integrating all data.
• Perform and QC water saturation modeling using Sw-h, Leverett-J, Lucia, Geo2Flow, or other appropriate modeling techniques. Develop workflows and guidelines for standardization of best-practices in saturation modeling.
• Perform volumetric calculations to determine STOIIP/GIIP.
• Identify key uncertainties impacting STOIIP/GIIP and hydrocarbon flow characteristics. Build alternative scenarios or realizations to calculate probabilistic range of STOIIP/GIIP and/or flow behavior. Develop workflows and guidelines for standardization of best-practices.
• Perform upscaling of reservoir structure & properties from fine-scale geologic model grids (Petrel) to coarse-scale (Eclipse) simulation model grids. Develop workflows and guidelines for standardization of best-practices in upscaling.
• Provide assistance as needed to Reservoir Engineers in simulation model history-matching, generation of prediction cases, and field development planning.
• Use geologic models to identify by-passed pay and generate opportunities for workovers, recompletions, sidetracks, infill drilling, pattern reconfiguration, and secondary or tertiary recovery.
• Assess staff competencies and develop training programs in reservoir characterization, geomodeling and development geology.
• Participate in and lead integrated reservoir management and surveillance projects.
• Present methodology & project evaluation to technical management.
• Document models in written reports and illustrate with cross sections, maps, cross plots, histograms, and summary tables. Develop standards for geologic model documentation.
• Lead software and technology evaluations related to the reservoir characterization, geomodeling and development geology disciplines.
• Mentor staff, develop training programs, and lead knowledge sharing initiatives.


 • Masters OR Ph.D. degree in Geoscience or related discipline
• Minimum of 15 years applicable experience in the Geoscience field.
• Expert user of Petrel 3D modeling software or equivalent with 10 years of continuous practice.
• Experience building complex, faulted structural frameworks with 3D seismic and well data including horizontal wells.
• Experience modeling carbonate and siliciclastic reservoir facies, porosity, permeability and water saturation in a variety of depositional settings based on core, capillary pressure, openhole log, and 3D seismic data.
• Experience in upscaling reservoir structure and properties and providing geologic modeling inputs to reservoir engineers on simulation projects.
• Experience with scenario- and Monte Carlo-based uncertainty modeling using industry-standard workflows.
• Experience in development geology and field development planning.
• Excellent communication, interpersonal and mentoring skills.
