n: a measure of the ability of a single fluid (such as water, gas, or oil) to flow through a rock formation when the formation is totally filled (saturated) with that fluid. The permeability measure of a rock filled with a single fluid is different from the permeability measure of the same rock filled with two or more fluids. Compare effective permeability, relative permeability.

permeability to a single phase fluid in a cleaned core.

straight or branched chain hydrocarbons with single bonded carbon atoms. Describes most oils.

n pi: hydrocarbons derived from or containing a benzene ring. Many have an odour. Singlering aromatic hydrocarbons are the benzene series (benzene, ethylbenzenes, and toluene). Aromatic hydrocarbons also include naphthalene and anthracene. Compare aliphatic hydrocarbons.

n: a transport of gas by displacement against the flow on a single pipeline, so that the gas is redelivered upstream of its point of receipt.

n: the process by which a single quantity of crude oil emulsion is broken into oil and water. The emulsion is gathered and stored in a tank or container prior to treating. Compare flow-line treating.

n: Usually refers to the operation that ogging device measures deviation angle and azimuth. There are two types: single-shot survey and multimetering.

v: unscrewing the drill stem into single joints and placing them 00 the pipe rack. The operation takes place 00 completion of the well, or in changing from one size of pipe to another. See lay down pipe.

n: Put the singles which are unloaded from drill pipe stand on the pipe carrier.

to separate the stands into single joints.

n: Completion with oil tube instead of casing in slim hole. The hydrocarbon flow is produced from oil tube. This completion program is suitable for the well with shallow oil zone and low produce.

n: the theory that the earths landforms assumed their present configuration in a brief episode at the beginning of geologic history-possibly in a single great catastrophic event-and have remained relatively unchanged since that time. Compare uniformtarianism. catcher n: a device fitted into a junk basket that retains the junk picked up by the basket catch samples v: to obtain cuttings for geological information as formations are penetrated by the bit The samples are obtained from drilling fluid as it emerges from the wellbore or, in cable-tool drilling, from the bailer. Cuttings are carefully washed until they are free of foreign matter, dried, and labelled to indicate the depth at which they were obtained.
