| Abstract | This paper describes a new three dimensional numerical simulator, CPT, developed at Lawrence Berkeley Laboratories to understand the implications of chemical hydro thermal couple physical processes for geothermal reservoir engineering. CPT is an improved version of the well validated code PT use in several geothermal reservoir engineering studies. The use of model CPT is illustrated fro three different examples. In the first case, a dense fluid is injected into a partially penetrating well in the upper portion of a reservoir. In the second case, a geothermal reservoir containing carbonates is produced where the colder recharge water partly dissolved the carbonates as it flows toward the well. In the third case, the effects of using an injected cold front are examined for the case of injection and production wells connected by a fracture zone. |
