microbial enhanced oil recovery.

abbr: maximum efficiency rate.

maximum efficient recovery or rate.

n: the multiple passes or round trips of the displacer in a prover for purposes of determining a meter factor. v: to establish the meter factor by comparing meter through-put to a prover of known volume.

n: a device used to determine the accuracy of a meter. Two popular types are pipe provers and open tank provers. A pipe prover has a calibrated pipe that contains a known volume. A sphere displaces oil or liquid product through the pipe while the meter being proved registers the amount of oil or liquid displaced. The meters reading is then compared to the known volume in the pipe. An open tank prover is a calibrated tank that contains a known volume. Oil or liquid product is put into the tank while the meter being proved registers the amount. The meters reading is then compared to the known volume in the tank.

n: a device in a pipe prover that. when actuated by the displacer sphere. registers pulses sent from a pulse generator on the meter being proved. By reading the number of pulses the counter registers, the amount of oil or liquid product the meter registered as having passed through the prover can be determined. The amount the meter registered is then compared to the known volume of the prover to determine the meters accuracy. See meter prove1;pipe prove,;

n: any single prover volume measurement in a set of prover volume measurements required to prove a meter.

n: a method of improved oil recovery in which chemicals dissolved in water are pumped into a reservoir through injection wells to mobilise oil left behind after primary or secondary recovery and to move it toward production wells. The chemical solution includes surfactants or surfactant-forming chemicals that reduce the interfacial and capillary forces between oil and water. releasing the oil and carrying it out of the pores where it has been trapped. The solution may also contain cosurfactants to match the viscosity of the solution to that of the oil to stabilise the solution and to prevent its adsorption by reservoir rock. An electrolyte is often added to aid in adjusting viscosity. Injection of the chemical solution is followed by a slug of water thickened with a polymer. which pushes the released oil through the reservoir. decreases the effective permeability of established channels so that new channels are opened. and serves as a mobility buffer between the chemical solution and the final injection of water.

the small energy emissions from small feature tectonic events, including production of fluids from a reservoir and the resultant transfer of overburden to the matrix of the reservoir.

n: a bird that moves (migrates) from one place to another, usually in connection with changing seasons. During times of migration, such birds, especially those attracted to bothes of water, may choose to rest in a drilling rigs reserve pit. To prevent harm to the birds, rig owners place netting over the pit so that they cannot alight in the liquid in the pit.

n: a special mill made up on the bottom of an overshot to grind away the top of a damaged fish so that the overshot can engage the fish. See overshot.
