Value methodology identifies energy-saving challenges and opportunities

The objective of the complete paper is to investigate and analyze energy-saving and processoptimization 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 valueengineering methodology. © 2020 Society of Petroleum Engineers.
