adv: 1. toward the stem of a ship or mobile offshore drilling rig. 2. behind. 3. farther aft than. See aft.

v: to cease producing oil and gas from a well when it becomes unprofitable or to cease further work on a newly drilled well when it proves not to contain profitable quantities of oil or gas. Several steps are involved: part of the casing may be removed and salvaged;one or more cement plugs are placed in the borehole to prevent migration of fluids between the different formations penetrated by the borehole;and the well is abandoned. In most oil-producing states, it is necessary to secure permission from official agencies before a well may be abandoned.

to cease efforts to produce or inject fluids in a wells and to plug the well sufficiently to protect the environment and the ability to redrill and develop other reserves at a later date.

n: 1. A vertical, cylindrical vessel that recovers heavier hydorcarbons from a mixture of predominantly lighter hydrocarbons. Also called absorption tower. 2. A vessel in which gas is dehydrated by being bubbled through glycol. See absorb.

n: It refers to the row tube holding thezinky
material during the analysis of drilling fluid. Used to survey the content
of H2S.

a vertical, cylindrical vessel that recovers heavier (longer carbon chain) hydrocarbons from a mixture of lighter hydrocarbons.

n pl: the characteristic patterns for various degrees of cement bonding between the casing and the borehole that appear on an oscilloscope display when a sonic cement bond log is made.

near formation area is irradiated with neutrons that transform some nuclei into isotopes. The isotopes produced can be detected by radioactive energy levels and decay time. The original elements can be described from this behavior.

n: one of usually two, three, or more mud tanks that holds drilling mud that is being circulated into a borehole during drilling. They are called active tanks because they hold mud that is currently being circulated.

n: see air-cooled exchanger. aerial river crossing n: a river crossing technique in which a pipeline is either suspended by cables over a waterway or attached to the girders of a bridge designed to carry vehicular traffic.

n: 1. a hand tool that is powered pneumatically. 2. a chamber filled with compressed air, often used offshore in seismic exploration. As the gun is trailed behind a boat, air is released, making a low frequency popping noise, which penetrates the subsurface rock layers and is reflected by the layers. Sensitive hydrophones receive the reflections and transmit them to recording equipment on the boat.

seismic source for ocean seismic work.

a comparable reservoir with many similar characteristics (e.g., lithology, depositional environment, porosity, perm, drive mechanism, produced fluids, etc.) that can be used for behavior projections comparison studies.

a component (e.g., bend stiffeners and buoyancy modules) used to control flexible pipe behavior.
