The objective of the complete paper is to investigate and analyze energy-saving and process-optimization opportunities in upstream surface facilities, from downhole to the gas/oil separation plants (GOSPs), using a value-methodology approach. Function analysis was used to identify those functions that can be reduced, eliminated, or synergized to minimize GOSP operating and maintenance cost. All successful opportunities were selected on the basis of their minimum operating expenses and capital expenditure (CAPEX) with a value-engineering methodology.
Introduction
Value methodology has been implemented successfully in new projects to save costs but rarely has been implemented in oil and gas operating facilities to minimize operating costs. The success of value methodology in reducing capital project costs prompted the author to explore its application to operating facilities, specifically toward minimizing operating and maintenance cost.
