system 11: a type of tap sampling system found on liquid storage tanks. The permanently installed taps on the out- side of the tank are attached to pipes and a floating boom inside the tank that rises and falls with the liquid level.

n: a spot sample of free water taken from beneath the petroleum contained in a ship or barge compartment or a storage tank.

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: The dynamic or hydraulic pump installed in hi-pressure liquid storage tank.

n: a sample of a substance that is made up of equal portions of two or more spot samples obtained from a tank or pipeline. In a crude oil storage tank, one type of composite sample is taken at the top, at the bottom, and in the middle.

n: 1. a small portion of a formation obtained by using a core bit in an existing wellbore. See core bit. 2. a spot sample of the contents of an oil or oil product storage tank usually obtained with a thief, or core sampler, at a given height in the tank.

n: The rock sample whose diameter is from 50mm to 100mm ,acquired from bottom hole when core drilling.

n: any fitting, appurtenance, or structural member that affects the capacity of an oil storage tank. It is positive if it increases tank capacity and negative if it decreases capacity.

n: 1. a European term for the depth of liquid in a storage tank. 2. formation dip. See formation dip. iMage. ullage.

n: the angle at which the bed of formation slopes away from the horizon

the angle that the structural surface or bedding plane or fault surface makes with the horizontal. Measured perpendicular to the strike and in the vertical plane.
