Field Development Planning has been prevalent in the Petroleum Industry since the first development projects.
Uncertainty in crude prices, advancements in technology and the decreased quality of newly discovered reservoirs; means that field development plans now involve much greater detail.
Given the large initial investments for the projects, it is also imperative to explore all field development options in detail and document the evaluation to ensure optimal development.
Exploration and exploitation:
- Review and validation of existing data
- 3D static modeling
Three-dimensional geological models of the subsurface, generated with geostatistical methods, are used for improving the management of oil reservoirs and aquifers (Koltermann and Gorelick 1996).
Subsurface facies models are usually limited due to sparse sampling of the sedimentary heterogeneity by wells, bore holes and the seismic data resolution limits. 3D geological model supporting the reservoir simulation, numerical reservoir models are extensively used to determine in-place hydrocarbon resources and recoverable reserve. Geosttistical techniques are being increasingly used to construct such numerical models. 3D reservoir model is a three dimensional data where all the geological information about the reservoir layers is collected and used.
Reservoir Modeling included many different techniques and software's in steps of the work. The first step involved a topologic three-dimensional construction, including all of the major geologic information.
Next is creating a refined grid to populate the model with rock-properties; corner point geometry grid will be built to honor the direction of major faults. Third is Facies characterization, where vertical proportion matrix.
