FEA

Finite element analysis

FEED

Front end engineering design. The FEED study is conducted after Conceptual Design, or the Feasibility Study. It includes basic engineering, focusing on project specific technical requirements and rough investment cost for the project. The FEED package is used as the basis for bidding the Execution Phase Contracts such as EPC or EPCI, and is used as the project design basis.

Flex Joint

Flex joints are flange assembles which allow for angular misalignment between the riser and the BOP, reducing stresses and reaction forces.

Flow Spool

Routes diverted flow to the rig or MPD choke manifold.

FPSO

Floating, Production, Storage and Offloading. A floating ship-shaped vessel which contains processing equipment and storage for hydrocarbons in a double hull. Once processes, an FPSO stores oil or gas before offloading processed petroleum to shuttle tankers or through pipelines.

Frac Gradient

The slope and pressure (psi/ft) at which a rock formation fractures or cracks and accepts fluid.

Frac Pressure

The pressure required to cause fractures in rock.
