n: a part of a LACT unit installed ahead of the metering equipment to separate and remove mass volumes of air and gas from the fluid.

n: the distribution of oil or gas produced from a well per unit of time. In a state using proration, this figure is established monthly by its conservation agency.

the process of determining ownership of hydrocarbons delivered to the meter or LACT unit on a lease.

n: the volume of oil delivered to a pipeline in a complete cycle of a measuring tank in a LACT installation. A series of such dumps covered by a single scheduling ticket is called a run.

n: a naturally occurring hydrophilic polysaccharide derived from the seed of the guar plant. The gum is chemically classified as a galactomannan. Guar gum slurries made up in clear fresh or brine water possess pseudoplastic flow properties.

n: A hydrophilic polysaccharide from the seed of the guar plant. It is a galactomannan type of saccharide that is highly dispersible into water and brines of various types and salinity. Its water solutions are non-Newtonian and also can be cross-linked by bo

abbr: lease automatic custody transfer.

lease automatic custody transfer unit. A calibrated measurement device used as an official sales point for crude oil transfer into a second party pipeline.

n: an automated system for measuring, sampling, and transferring oil from a lease gathering system into a pipeline. See lease automatic custody transfer.

n: (LACT) the measurement, sampling, and transfer of oil from the producers tanks to the connected pipeline on an automatic basis without a representative of either the producer or the gathering company having to be present. See LACT unit.

n: a calibrated tank that, by means of weirs, float switches, pressure switches, or similar devices, automatically measures the volume of liquid run in and then released. Measuring tanks are sometimes used in LACT systems. Also called metering tanks or dump tanks.

n: 1. an accurately calibrated, usually U-shaped, pipe used to check, or prove, the accuracy of a meter on a LACT unit or other oil measuring installation. 2. a type of continuous-flow volumetric prover comprising a length of pipe from which a known volume is displaced by a displacer to or from a meter being proved at normal operating conditions.

n: 1. a part of a LACT unit that removes foreign particles from the crude. which might disrupt the operation of closetolerance moving parts. 2. a device placed upstream of a meter to remove foreign material from the stream that might damage the meter or interfere with its operation. The strainer element is generally coarser than a filter designed to remove solid contaminants.
