University of Illinois Campus Deep Direct-Use Feasibility Study - Preliminary Geothermal Reservoir Model

Description

Preliminary geothermal reservoir simulations were performed using a homogeneous static model to evaluate and understand the effects of fluid and rock properties that could influence the delivery of thermal energy in a doublet system. A 5000 feet by 5100 feet by 500 feet homogeneous model having a constant porosity and permeability of 20% and 100 mD was used to perform preliminary geothermal reservoir simulations. The model was discretized in the x-, y-, and z-directions into 100, 101, and 100, gridblocks. Two wells were placed on the opposite ends of the central column of the discretized model. One of the wells was designated as a producer and the other an injector. Equal volumes of water was extracted and then injected into the reservoir via the production and injection wells. Water was extracted at a temperature of 109 deg F and re-injected at 50 deg F at the 1000 bbl/day. The files attached contains the input and output files of this simulation case. The input and some of the output files can be viewed in any text editor.

57 Database for local grid refinement (LGR) option. VIP-LGR improves the resolution and detail of a reservoir study without a large amount of extra computer CPU time or memory. The LGR option minimizes the number of grid blocks, and therefore the CPU time required to perform detailed simulation in a full field model by allowing the grid to be selectively refined in areas where more grid definition is required. https://gdr.openei.org/files/1065/mtsim_lgr_vdb.zip
