Basic Aims
Improved characterisation and incorporation of faults in flow models is a pre-requisite to optimising production strategies within structurally complex reservoirs. A geologically palatable method for attaching fault transmissibility multipliers to reservoir flow simulation models has recently been jointly developed and implemented in commercial software, referred to as TransGen, by the project partners. The proposed project will develop beyond our existing capabilities, which determine fault transmissibility multipliers as a function of fault-rock thickness and single-phase permeability, to develop a suite of methods implemented in modular software for the incorporation of fault-zone geometries and two-phase fault-rock properties in reservoir flow simulators. The methodologies will be complemented by research that examines the calibration of fault property and geometry predictors to dynamic reservoir flow information.
This project will contribute to an improvement in the effectiveness of reservoir assessment and management and improve recovery from reservoirs by the development and implementation of innovative, geologically-driven, methods for handling faults in reservoir production simulation through the following tasks: (i) Improved flexibility in fault-rock property assignment. (ii) Routine inclusion of sub-resolution fault-zone structure. (iii) Routine inclusion of two-phase fault-rock properties. (iv) Calibration of algorithms against reservoir production data. These developments will be implemented as modules in the TransGen software system, and are the principal project deliverables. All modules will be accessed through a menu-driven graphical interface for ease of application. TransGen input, output and transmissibility calculations, are compatible with the Eclipse flow simulator.
Illustrations of TransGen functionality for a Northern North Sea reservoir are provided in the TransGen Gallery and additional TransGen graphics are available on a downloadable pdf. For commercial enquiries see Badleys.
