| Abstract |
Drilling wells is probably one of the highest capital expenditure, and highest risk for geothermal industries today, starting from exploration, delineation, initial wells for production and infill when an existing wells production are declined. It is estimating cost of 3-15 MM $ for drilling new wells for geothermal industry today, which is required a high level of decision making from high level of management. To make the right decision on spending a high capital expenditure on drilling require multi principle workforce, such as Drilling engineer, Geologist, production engineer, Reservoir engineer, Drilling side manager , etc. to planning ,design wells, and execution. Many time, the group of work force has conflict on their own objective, such as geologist required to know information, reservoir engineer required to maximize production rate and drilling engineer required to lower well cost. Challenge for decision maker is always on how to compromise between working team and making the right decision. This paper will illustrate the process and methodology of Project management process which Chevron Geothermal Indonesia used for the right decision making. The result has proven success of 2012-2013 Salak Drilling Campaign which is currently estimation of 10-15 million dollars saving from the original plan, steam supply meet requirement, water injection meet requirement which required to drill 2 wells less and plan, and know value of information for decision of new PAD location will b construction for future infill wells. |
