n: The physicist A. E. Boycott found that the blood cell deposits faster when test tube deflects, especially 40°-50°, than when test tube is vertical. The same situation will be found in the drilling fluid in the horizontal well. That is why people call this

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: a private company in the business of preparing abstracts of title and performing related services. Also called abstract plant.

n: a procedure whereby a product may be subjected to intensified but controlled conditions of heat, pressure, radiation, or other variables to produce, in a short time, the effects of long- time storage or use under normal conditions.

a piece of equipment that connects pipe, flanges or other equipment with different root threads or connection mechanisms.

n: a method of asserting and gaining title to property against other claimants, including the owner of record. The claim through adverse possession must include certain acts (as required by statute) over an uninterrupted interval of time. It must also be, in most states, open," "notorious," and "hostile."

n: a hoist operated by compressed air;a pneumatic hoist. Air hoists are often mounted on the rig floor and are used to lift joints of pipe and other heavy objects.

n: an atmospheric fin tube exchanger that utilises air for cooling. Ambient air contacts the external fins by fanforced or natural draft. Also called air-fin unit or aerial cooler.

n: the combining power of a base, or alkali, as measured by the number of equivalents of an acid with which it reacts to form a salt. Any solution that bas a pH greater than 7 is alkaline. See pH.

n: The combining power of a base measured by the maximum number of equivalents of an acid with which it can react to form a salt. In water analysis, it represents the carbonates, bicarbonates, hydroxides and occasionally the borates, silicates and phosphates

n: The drilling fluid filtrate reducer of amylum derivant that amylum reacts with alkyl sulfate in the alcaline condition.
