7th SPE Comparative Study
Description
The problem from the SPE-21221-MS paper is a test for modelling pressure drop in horizontal wells due to the wellbore friction.
The problem description can be found in Nghiem, L. et al. 1991. Seventh SPE Comparative Solution Project: Modelling of Horizontal Wells
in Reservoir Simulation. SPE Symposium on Reservoir Simulation, 17-20 February, Anaheim, California
DOI: 10.2118/21221-MS.
This example involves production of hydrocarbons from a horizontal well where conning tendencies are important.
The pressure drop in wellbore due to the friction is simulated. The effect of well length and rates on the recovery is examined.
The water flow to the horizontal wellbore from the water zone below water-oil contact is simulated with a line source of water.
Although from the physical point of view the wellbore friction is irrelevant in this problem, the example demonstrates MUFITS options for modelling well hydraulics.
The example includes both a multisegment well, that is used for hydrocarbon production, and the default average-well model used for modelling water flux from the water zone.
