Senior Geomodeler

Transguard Workforce Solutions is now recruiting for a Senior Geomodeler for a client in the oil and gas industry.

In this role, your responsibilities include the following:

• Building, maintaining, evaluating, and applying integrated ‘fit-for-purpose’ 3D geological models for dynamic reservoir simulation studies, field development planning/ execution, reservoir surveillance and business planning.
• Incorporating all geological, geophysical, petrophysical and dynamic constraints and interpretations in 3D static models according to the organisation’s best practices and procedures.
• Directing and participating in geological reservoir studies aimed at constructing and/or improving geological models, including coordinating, and defining coring, logging and testing requirements.
• Coordinating and checking the preparation of geological requirements and geological predictions of appraisal and development wells.
• To quality-check and validate all input reservoir data/ interpretations used in building 3D static models, including geophysics (seismic horizons / faults), petrophysics (porosity/permeability and fluid saturation), reservoir geology (stratigraphic formation tops, core and log interpretations) and reservoir performance data (well tests, PLTs, RSTs etc.)
• Integrating all local and regional reservoir data/interpretations in building conceptual geological models represented in 3D depositional block diagrams, facies & diagenesis maps, thickness & property maps, cross-sections, sequence stratigraphic framework and lithological correlations.
• Constructing realistic reservoir structural models, based on seismic interpretation (faults / horizons), formation tops, structural geology concept, regional settings and tectonic history of the field.
• Conducting detailed geostatistical analysis of reservoir facies, diagenesis and petrophysical properties and define geologically significant spatial and vertical trends, estimate residual variogram models, proportion maps and probability cubes to constrain 3D property distribution.
• Performing 3D property distribution/modelling consistent with facies interpretation, depositional environments and diagenesis based on cores analysis, seismic and well logs interpretation to reconcile the geological concept with the 3D model.
• Performing volumetric computations and subsurface uncertainty analysis based on all inputs/ assumptions in the 3D static model including area of trap, net reservoir thickness, porosity, permeability, hydrocarbon saturation, recovery factor and formation volume factor.
• Extracting average property maps, cross-sections, and statistical data from geological/simulation model(s) to validate and QC input data of property distributions. 
• Analyzing distribution of rock types, porosity, permeability, and saturation using geostatistical techniques, including SIS, SGS, Cloud Transform and saturation height functions.

The ideal candidate will have the following skills and experience:

• Minimum BSc / B.Tech in Geology / Geoscience/Petroleum Engineering or equivalent.
• 15+ years of experience as a Geomodeler, preferred in the region/UAE
• Background in Geomodelling and skills in integrating inputs for static.
• Experience in log interpretation and analysis
• Software experience: PETREL
