Static Model Building

Viridien’s specialist geomodeling department is supported by world-class seismic, sedimentological, stratigraphic, GIS mapping, petrophysical and reservoir engineering personnel. The geological model is the place where all of these data are integrated and made sense of. We focus on providing clients with the big picture based on quality inputs, while all the time keeping strong focus on their ultimate aims. Our geological models are used as the basis for dynamic reservoir simulations and fully independent FDPs (field development plans) and advice. Our experienced economics department is able to advise on FDP optimization, asset value and financial risk.

The main components of our static model building workflow and methodology are:

Data loading, expert QC and analysis
Integration of regional, sedimentological, diagenetic, petrophysical and reservoir architectural understanding
Incorporation of sedimentological, seismic, petrophysical and reservoir engineering data
Structural modeling
Facies and reservoir property modeling
Saturation modeling and QC
Volumetric determinations and uncertainty analysis
Migration-to-reservoir simulator and initialization support

Classical Reservoir Engineering

Viridien’s Reservoir Sciences group is well versed with use of analytical reservoir engineering techniques and puts special emphasis on harnessing the results from analytical methods with static and dynamic modeling workflows. Our experts utilize industry-accepted software and in-house analytical tools to conduct their analyses. At Viridien, we appreciate that each reservoir has unique issues, so our experts use tailored workflows to address these and meet our clients’ needs.

Dynamic Modeling

Viridien has the capability to simulate very large, high-resolution dynamic models with fine grids utilizing workflows tailored for assets at different stages of the E&P life cycle. Our experts use the industry-standard commercial simulation platforms and have global experience in dynamic modeling of complex carbonate and clastic reservoirs with a variety of reservoir fluids. They can recommend optimized field development plans under primary, secondary and tertiary recovery schemes. Viridien also utilizes a new proprietary ensemble-based history-matching workflow to condition static models to production data so that they are more detailed and realistic, and to refine history-matching results.

Surface Modeling and Economics

Once the dynamic reservoir properties have been generated, Viridien can now conduct well- and field-level optimization studies to help clients select the best interface between reservoir and surface facility. Key components of this solution will be:

Completion design
Artificial lift design and optimization
Flow assurance
Metallurgy selection
Corrosion assessment
Well performance (vertical lift curves)
Production system flow
Pipeline geometry
Separator pressures
System constraints and GAP analysis

After the production forecasts have been generated, cost profiles are created for operating costs (OpEx) and capital costs (CapEx) as well as abandonment costs. The project can be optimized for the commercial terms and product prices:

Modeling of fiscal terms and the creation of an economics model
Economics model outputs will be cash flow, NPV, rate of return, EMVs (for exploration and prospects), and other metrics as required
Analysis of the economics model outputs to select the optimum development scenario

Economic modeling for surface and subsurface

Geomechanics
