n: the gasoline extracted from natural gas by putting the gas into contact with oil in a vessel and subsequently distilling the gasoline from the heavier oil.

gasoline extracted from wet natural gas by putting the gas in contact with oil.

n: Native American land designated for use by a specific individual, although the title is still held by the United States.

n: any distillation made in accordance with ASTM procedure. Generally refers to a distillation test to determine the initial boiling point, the temperature at which percentage fractionations of the sample are distilled, the final boiling point, and quantity of residue.

n: a mixture of liquids that distills without a change in composition. The azeotropic mixture exhibits a constant maximum or minimum boiling point, which is either higher or lower than that of its components.

n: a ratchet device on a crane that prevents the boom of the crane from being lowered but still permits it to be raised. Also called a boom ratchet.

n pi: 1. the liquids and the residue that collect in the bottom of a vessel (such as tank bottoms) or that remain in the bottom of a storage tank after a period of service.2. the residual fractions remaining at the bottom of a fractionating tower after lighter components have been distilled off as vapours.

n: a process used to repair a hole in the casing by pumping cement down tubing or drill pipe. First. the casinghead, or bradenhead, is closed to prevent fluid from moving up the casing. Then the rigs pumps are started. Pump pressure moves the cement out of the tubing or pipe and, since the top of the casing is closed, the cement goes into the hole in the casing. The tubing or pipe is pulled from the well and the cement allowed to harden. The hardened cement seals the hole in the casing. Although the term bradenhead squeezing" is still used, the term ,."bradenhead" is obsolete. See annular space. casinghead, squeeze.

n: a rock formation that contains large open spaces, usually resulting from the dissolving of soluble substances by formation waters that may still be present. See vug.

n: A formation having columinous voids, usually the result of dissolving by formation waters which may or may not be still present.

n: The sclereid phenomenon after cement slurry keeps still for a while.

n: a test standardised by the American Gas Association and the Gas Processor Association for determining the natural gasoline content of a given natural gas. The gasoline is adsorbed from the gas on activated charcoal and then recovered by distillation. The test is described in Testing Code 101-43, a joint AGA and GPA publication.
