| Summary: | Production decline happened as X geothermal field being produced commercially since 1983. Well production decline rate evaluation is performed in purpose of extending the field production time. The used method is well-known Arps empiric method. Each well production decline rate is calculated and analyzed by how far re-injection programs affect production wells performance around injection well. The evaluation shows different production decline rate for each well in range 0.2-48.11 % /year and 7.09% /year average field production decline. Well 36, 37, and 38 give positive effect and so their operation can be still performed or considered. Well 39 and 40 give negative effect. Well 41 and 42 operations have to be reevaluated if there's appropriate data already. Low permeability area around well 5 and south well 4 can be considered as an injection area for south-east X Field site in supplying the new 60 MW unit. |
