An early-stage study which defines the basic nature of a project, taking account of all stakeholder requirements; it produces a scoping design, outline cost estimate and sometimes project economics. A FEED study is often used as a critical stage document on which agreement is necessary before a project proceeds to the next stage of partner commitment and is always used in oil and gas exploration and development projects prior to the final development phase. For a gas field development, the objective of the FEED study is to verify the field operator’s engineering assumptions in or to enable them to commit to potential buyers with a firm gas price. Often commitment to buyers on price without FEED will expose the joint venture to significant risk should actual capital expenditure be more than estimated. FEED is therefore a critical phase to progression of gas sales activities

Future production of an oil or gas asset and development costs, which include dismantlement and restoration expense, are computed by estimating the expenditures to be incurred in developing and producing the proved crude oil and natural gas reserves at the end of the year, based on year-end costs, and assuming continuation of existing economic conditions

The process whereby separated associated gas is pumped back into a reservoir for conservation purposes or to maintain the reservoir pressure

Fouling is the build up of oil deposits on tubes in heat exchangers. Fouling problems in refineries worldwide are causing the loss of about 7 million bbl/year of throughput capacity. Refiners spend $4.5 billion worldwide to clean up refineries, resulting in shutdowns and serious health and safety issues because of the need to safely dispose of toxic material from the tubes. Security of oil supplies also is threatened when refineries are offline.
