Abstract
The strict environmental standards for disposal of waste geothermal brine to surface waters has constrained the testing of production wells at Sibayak geothermal field. The alternative action is to reinject waste brine into the ground but it is constrained by the high potential of silica deposition in the injection well. It is shown on the operations of reiljecting waste brine at low (ambient) temperature which has not successfully undertaken at Sibayak. The lesson from these operations, PERTAMINA will implement an action plan at Sibayak by considering an experiment result at Mac-Ban geothermal field.
