A geologically directed drilling effort to obtain information pertaining to a specific geological condition that might lead toward the discovery of an accumulation of hydrocarbons. Such wells are customarily drilled without the intention of being completed for hydrocarbon production. This classification also includes tests identified as core tests and all types of expendable holes related …
A trap in reservoir rock which has been formed by the deformation (folding or faulting) of the rock layer. There are three basic forms of a structural trap in petroleum geology: anticline trap, fault trap and salt dome trap all of which result in barriers which form traps
A term used to describe the overall relationship of rock masses e.g. folding, faulting, unconformities
A type of coal that is dull black and has less moisture than lignite. Subbituminous is generally used to produce steam for electricity generation
An oil and gas development project is sub-commercial if the degree of commitment is not such that the accumulation is expected to be developed and placed on production within a reasonable time frame which is usually limited to around 5 years
Has been used in the harsh North Sea for offshore loading of crude oil and is now also developed for discharge of natural gas and can be used as an offshore LNG receiving terminal. In this case an LNG regasification vessel connects to the STL buoy and sends vaporized/re-gasified LNG through the flexible riser and …
A wellhead installed on the sea floor and controlled remotely from a platform, a floating production facility or land
SSVs are the fleet of offshore support vessels that provide what is known as ‘good prospect of rescue and recovery’ for the personnel onboard offshore installations platforms whilst carrying out their work on site.
US holds strategic reserves of oil and gas. The reserve achieved its originally mandated goal of 90 days of import protection in 1983 and reached 118 days’ supply in 1985 before Congress discontinued funding to buy oil and purchases were suspended in 1994. Current reserves as of beginning of 2008 stand at about 58 days …
A particular type of floating vessel, usually used as a mobile offshore drilling unit (MODU) that is supported primarily on large pontoon-like structures submerged below the sea-surface. The operating decks are elevated 100 or more feet [30 m] above the pontoons on large steel columns. Once on the desired location, this type of structure is …
