The well test data is of variable quality, and especially the data from well KMJ-43 was difficult to interpret due to short duration of injection steps. Estimated storativity values are relatively high, especially for the wells in Kamojang. An explanation of the high storativity is that Kamojang is a vapor dominated system, but it should also be remembered that injection tests are not ideal for storativity determinations compared with interference tests. Both the Kamojang and the Krafla reservoirs are fractured reservoirs. It is therefore not surprising that the well test analysis yield negative skin values for the wells.
Further comparison is recommended.
By combining measured circulation losses and a sequence of temperature profiles from the well, the position of 9 aquifers was determined. The maximum reservoir temperature measured is 238 C. Comparison of the two, the mineral temperatures and the measured, indicates that some cooling of the reservoir has taken place in geological time. Further study and comparison with the other wells is recommended. Intrusive rocks are inferred at four depth intervals. The well showed a very low permeability and could not be discharged.
