n: 1. a derrick or crane shaped like the letter A and used to handle heavy loads. 2. an A-shaped openwork structure that is the stationary and supporting component of the mast of a jackknife rig and to which the mast is anchored when it is in an upright or drilling position. 3. the uppermost section of a standard derrick, shaped like the letter A and used as a support in lifting objects such as the crown block to the water table.

n: A kind of "A" frame gin pole, used to elevate heavy object.

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: a large, sloping sedimentary deposit at the mouth of a canyon, laid down by intermittently flowing water, especially in arid climates, and composed of gravel and sand. The deposit tends to be coarse and unworked, with angular, poorly sorted grains in thin, overlapping sheets. A line of fans may eventually coalesce into an apron that grows broader and higher as the slopes above are eroded away.

land counterpart of a river delta. Characteristic of sediments that have been transported by a fast moving stream then dropped out of the flow as the stream velocity drops as it spreads out. Typical of zones of heavy water runoff such as found at the base

n: a hard brown or black material composed principally of hydrocarbons. It is insoluble in water but soluble in gasoline and can be obtained by heating some petroleum, coal tar, or lignite tar. It is used for paving and roofing and in paints.

n: The vertical heigh from the top of girder of drill floor to the bottom surface of crownblock beam.

n: The pulley installed in the top of derrick. Used to spur on bailer.

n: the cable attached to a bailer, passed over a sheave at the top of the derrick, and spooled on a reel.

n: The wire rope connected with bailer, winded to the drum through the pulley on the top of crown block.

n: I. the process of breaking down organic wastes with microbes. Bacteria that are naturally present in the environment use microbial enzymes to break down die materials into a soluble form that passes through the cell walls of the bacteria. The bacteria metabolise d1e material and convert it into components d1at are more readily assimilated in d1e environment, such as water or carbon dioxide (i.e., a gardeners compost pile). 2. the creation of engineered and managed conditions to boost natural bioremediation processes. Nutrients are added to stimulate the bacteria naturally present in the waste. Oxygen ari1 pH levels are adjusted for maximum effectiveness, and, if conditions are right, the bacteria grow in large numbers and break down the hydrocarbons much more rapidly than with natural bioremediation. In cases in which the necessary bacteria are not already present in the waste, suppliers can provide diem along with die appropriate nutrients.

Reworking of the sediment by burrowing animals.
