In this work a comprehensive investigation of the available models listed in the literature used for numerical simulation of transient pressure behaviour of horizontal wells was performed. Then, a sensitivity analysis focusing on the effect of grid size selection and the representation...

In particular, the coupling of geomechanical stress-strain computation introduces a completely separate second grid, which is usually larger in all three dimensions. Since the CPU time required...

This paper will provide examples of the application of these leading edge technologies for in situ oil sands development, including the Surmont area of the Athabasca deposit. Introduction The investigation...

... Abstract A new method for the determination of finely gridded reservoir simulation pressures has been developed. It is estimated to be as much as tens to hundreds of times faster than other methods for very large reservoir simulation grids. The method extends the work of Weber et al. (CIPC...

... of fracturing naturallyfractured reservoirs. In this paper, the macro-fracture and micro-fracture in the same grid are named as composite natural fracture. Taken mass exchange between macro-fracture and matrix into account, the multi-medium percolation model with macro-fracture is set up. The simulator of post...

... Abstract The objective of this study is to develop an upscaling methodology for simulation of oil-water displacement in fractured porous media. The "real response" is determined from 2-D fine grid models that explicitly incorporate given fracture distributions. The fine-grid models are used...

... that incorporate the sharp pressure gradients that occur around the wells. Streamline simulation. The reservoir pressures are used to determine the location of the streamlines. Saturations are then determined by 1-D solutions along each streamline. Dynamic gridding. The saturations on each streamline...

This work formulates and compares different methods of representing a hydraulic fracture in a single-phase and multi-phase reservoir simulator, assuming that the fracture will extend over...

... is presented which allows to reduce the computational time without any loss of precision. This approach, based on a dynamic sub-gridding technique, acts as an external and independent mesh generator and does not rely on any specific simulator. To this respect, it provides an effective alternative tool...

... Abstract The objective of this study is to develop an upscaling methodology for simulation of tracer injection in naturally fractured reservoirs. 2-D fine grid models that explicitly incorporate fractures are used to represent the realistic fracture distribution from geostatistical...

The tensor orientation effect introduces an error in the magnitude and shape of pressure field, which depends on the relative orientation of the grid in relation to the principal axes of the permeability tensor. This problem has been solved by developing a 13-point...

...-resolution models are often too large to process through numerical flow simulators. Upscaling methods are required that reduce the size of detailed models while preserving the important geological characteristics of the reservoir. Most upscaling methods currently in vogue work with uniform grids. A new...

The multipoint flux approximation (MPFA) scheme developed in recent years provides an improved method for modelling tensorial permeabilities in non-uniform and skewed grids that are often required for proper representation of the reservoir geometry. The physical dispersion...

... Abstract The windowing technique was introduced in 1993 by Heinemann and Deimbacher (Ref 9). This method allows a locally restricted and time-dependent replacement of grids and parameters during simulation runs. Windows can represent any area of special interest in a reservoir. In most cases...
