Abstract
Lahendong field production which started in 2001 has been gradually expanded to its current capacity of 80 MWe. Brine and condensate fluids are re-injected back into the reservoir through LHD-7 cluster at low temperature. Changes in characteristics of production fluids from several wells have been observed. Tracer tests were conducted to further study the results and effects of reinjection. Tracers found in production fluids indicate different rate of breakthrough to production wells. Presented is the 2013 Lahendong tracer test including the planning, execution, and monitoring. Effects of reinjection fluid that has been observed are also presented here.
