n: a marking on the pin and the box of a tool joint that gauges the amount of metal that can be safely removed when

a selected reference point for comparing performance.

n: 1. a table that shows the capacities of, or volumes in, a tank for various liquid levels measured from the dip point or from the ullage reference point. Also called gauge or tank capacity table. 2. a table that is developed by recognised industry methods to represent volumes in each tank according to the liquid (image) or empty space (ullage) measured in the tank. Also called tank capacity table, tank table.

n: I. the vertical distance between the top of an anticline., or dome, and the bottom, an indication of the amount of producing formation that may be expected. 2. the process of closing down a site, such as plugging and abandoning a well or filling in a pit.

n: the shortest horizontal distance from a particular survey station back to the reference point

n: a level metal plate attached to the tank shell or bottom and located directly under the gauging reference point to provide a fixed contact surface from which liquid depth measurement can be made.

n: a European term for a point marked on the dip hatch of a tank directly above the dip point to indicate the position at which dipping should be carried out.

n: a European term for the depth of liquid in a tank. corresponding to a given ullage. It is obtained by subtracting the observed ullage from the height of the ullage reference point above the dip point on the bottom of the tank.

n: the vertical distance from the reference point on the gauge hatch to the bottom of the tank or to the datum plate.

n: determining the liquid level of a tank so that its volume can be calculated. Usually done by lowering a weighted graduated steel tape through the tank roof and noting the level at which the oil surface cuts the tape when the weight gently touches the tank bottom. It can also be done by measuring the distance between liquid height and a reference point and subtracting the distance from the gauge height to determine liquid height.

n: a double index scale against which a fixed reference pointer may be moved to correct for variations in gravity from a base point computed for water at 60�F. The compensator is marked in both specific gravity and API gravity units.

n: a scale in which the distances of numbers from a reference point are proportional to the logarithms of the numbers.
