| Abstract | Attempts were made at Kamojang Geothermal field, West Java, to apply Modified Isochronal Test to determine output curve from production test of KMJ-73 and KMJ-74 wells. In the past, wells at the Kamojang Geothermal field were tested using Back Pressure Method. The results of the test were satisfactory. However, the test was time consuming. Three months were spent testing a single well. The disadvantages of this test are high cost and delayed revenue gained from the wells. The result of the modified isochronal test has a good agreement with those obtained from back pressure test. The main advantage of modified isochronal test is duration of the test. Completion of modified isochronal test takes only 10 days. However, before it becomes an alternative method for testing dry steam wells, validation of this method is needed by applying it to other wells. |
