A Technical Review of Interference Testing with Application in the Ohaaki Geothermal Field
Abstract/Contents
- Abstract
- The chronology and mathematical development of interference testing and related earth tide andcompressibility effects are reviewed. Hydrological information from field tests performed in the Ohaaki geothermal field since first development in 1965 is summarized. Data from 12 interference tests (four on the same doublet) performed in the deep Ohaaki reservoir between 1979 and 1983 are analyzed using conventional log-log and semi-log type curve matching techniques along with recently developed semi-log type curve matching techniques which allow linear boundary detection without the necessity to develop two semi-log straight lines or the need to know reservoir parameters. Data in nine tests were recorded using water level chart recording devices while data in the remaining three were recorded using quartz crystal pressure gauges. Both instruments have a resolution of about 100Pa.Some tests show the presence of a no-flow boundary for which the inference ellipses have been located. Interpretation is made on the probable location of the no-flow boundary. A study of the significance of early time data and other factors shows that vastly different reservoir parameters can be obtained unless careful interpretation is made. A hydrological model of the Ohaaki geothermal field is presented.
