| Abstract |
Pressure/Temperature/Spinner(P/T/S) logging tool is very effective to obtain the following important parameters of geothermal well. Usually, one static logging, multiple step flow rate production (or injection) loggings and one build-up (or fall-off) logging are carried out as a set logging for each well. It is possible and rather common to analyze some reservoir parameters (depth and flow rate of each feed point, transmissivity. Skin effect, etc.) under one-phase condition. However, two-phase (liquid and steam) condition sometimes occur in the reservoir. As everybody knows, in this case, it is very difficult to analyze these parameters because in general the approach for analyzing these pressure transient test is based on unboundary, homogeneous, isotropic, and confined reservoir model or the extended model of it. This paper represents some of the research of two-phase condition analysis which uses twophase reservoir simulator and two-phase well bore simulator on production. |
