Home/use of corner point geometry in reservoir simulation
To model fault planes in corner point grids, the cell corners or nodes can be split, as in the case of a fault lying between two cells. This can be seen in Figure 4-5, the nodes representing the bottom right of cell (10,1,1) do not have to coincide with the nodes representing the top left of cell (11,1,1).
The production system model is of the multi- level hierarchical type used in ECLIPSE 100. Controls may be impose at the well, group or field level. Surface rate, reservoir rates, bottom-hole pressures, etc. may be controlled. It is possible to re-inject a fraction of the production of specified well or group.
reservoir model because there are no signs of a bottomwater zone and the reservoir initial pressure is higher than the bubble-point pressure (i.e., no gas cap). The initial phase saturations are imposed as the endpoint saturations in the relative permeability curves. Relative permeability curves are .
Reservoir Simulation | Software. The name ECLIPSE originally was an acronym for "EC´s Implicit Program for Simulation Engineering". ECLIPSE 100 solves the black oil equations (a fluid model) on corner-point grids. ECLIPSE 300 solves the reservoir flow equations for compositional hydrocarbon descriptions and thermal simulation.
The accuracy of streamline reservoir simulations depends strongly on the quality of the velocity ﬁeld and the accuracy of the stream-linetracingmethod. Forproblems describedoncomplexgrids(e.g., corner-point geometry or fully unstructured grids) with full-tensor permeabilities, advanced discretization methods, such as the family of multipoint ﬂux approximation (MPFA) schemes, are necessary
Streamline Simulation—8th International Forum on Reservoir Simulation, 2005 Marco R. Thiele Once the exit point location (xe,ye,ze) is known, it becomes the inlet position of the neighboring block and so the streamline can be traced from block to block as shown in Figure 6. Figure 6: (Left).
Moreover, this CPG geometry and schemes is fully compatible with those developed at IFP. So, the user may add wells to the data set generated at the present day by the basin simulator. Then, a reservoir simulation may be made on the basin mesh with initial and .

assumed to represent depositional space. For flow simulation performance, a dynamic grid with a reduced number of cells is built and properties are upscaled from the static grid. Strategies to regroup fine-scale cells into coarse-scale grid blocks vary but are very often limited by corner-point geometry and fixed topology of reservoir grids.
A new method for formulating finite difference equations for reservoir simulation has been developed. It can be applied throughout the entire simulated reservoir or to local segments. When applied to cells containing vertical, fully penetrating, straight-line wells in a homogeneous reservoir, the resulting equations are equivalent to Peaceman''s
Prior to joining the University of New South Wales, he worked for Esso Australia as a reservoir engineer both in Australia and abroad where he was responsible for conducting reservoir simulation studies and conducting and interpreting oil and gas well tests. He is an active consultant to industry in these areas.

(such as faults, irregulars borders, reservoir zones) which are not defined on the cartesian grids. Using present simulators, the real basin geometry is deformed and aligned on cartesian meshes. So, in this article, we have coupled LGR techniques with Corner Point Geometry (CPG) grids which allows to accurately integrate basin geometric features.
This paper presents a computationally efficient work flow for flow diagnostics on fully unstructured grids. The control volume finite element method (CVFEM) is employed to solve the elliptic pressure equation.
FlowSim Studio can handle both single and dual porosity reservoirs. It is extremely flexible and can be used to simulate complex reservoir structures using several grid options such as rectangular grids, radial grids, corner point geometry and automatic grid generation.
The following 10 points will highlight some of the key reasons why 3D geo-modeling and flow simulation must be part of the same software package. 1 - Validation of up-scaled reservoir models Up-scaling is a required step in most reservoir studies; it consists of creating a 3D reservoir grid at a resolution coarser than the geological model then ...

porous rock formation (the reservoir). The geological model is realised as a grid populated with petrophysical or hydrological properties that are used as input to the flow model and together they make up the reser-voir simulation model. The geological model must also describe the geometry of the reservoir rock and in

Oct 11, 2014· Corner point geometry Grid blocks in corner point geometry can have their eight corners individually specified as long as they lie on straight (possibly sloping) co-ordinate lines joining the top and the bottom of the grid.
Reservoir simulation models are becoming increasingly sophisticated in tandem with the rapid development of geological modeling methods. Widely used commercial simulators usually model flow through heavily faulted and structurally complex geometries with the flexibility provided by corner-point geometry.
