Paper Number: PETSOC-99-32
... closed reservoir, and could be applied in the case of non-fractured reservoirs. I present some guidelines to handle this problem in numerical simulation attempts. The reason is because most numerical simulators will raise an "error flag" if an engineer attempts to input more than one contact within the...

... Abstract A steam injection reservoir simulator was developed with the objective of improving the resolution of the information concerning the flow around a well and between wells. To accomplish this objective, it was necessary to develop the contiguous hyperhybrid grid refinement method. With...

... Abstract Recent improvements in the speed of numerical compositional simulators has made it possible to use a large number of gridblocks to model condensate reservoirs, volatile reservoirs, and gas injection projects. This paper discusses techniques for choosing pseudo components so as to use...
