n: the electrical resistance offered to the passage of current;the opposite of conductivity.

n: the electrical resistance offered to the passage of a current, expressed in ohm-meter;the reciprocal of conductivity. Fresh-water muds are usually characterized by high resistivity, salt-water muds by a low resistivity.

measurement of a substance (or rock) to resist the flow of electric charge. Opposite of Conductance.

n: a component that tends to impede the flow of electric current, usually without any inductive or capacitive effects. Often used in conjunction with a voltmeter.

n: (RCRA) a federal regulatory program designed to ensure responsible man- agement of hazardous waste at all levels of contact. i.e., generation, transportation, treatment, storage, and disposal;regulates the management of onland disposal of all solid wastes. This comprehensive program is designed to protect human health and the envirorunent from the unintentional exposure to solid waste that is identified as hazardous waste." Also institutes a "cradle-to-grave" monitoring program that closely tracks and regulates the handling of hazardous waste from the time the waste is first generated until it is disposed.

n: the observed value of a variable determined by a single measurement.

n: in reservoir mechanics, the formation of liquid droplets in a gas as the well is produced and the pressure drops. Some hydrocarbons exist naturally above their critical temperature in the reservoir;as a result, when pressure is decreased, instead of expanding to form a gas, they condense to form a liquid.

n: a dip-slip fault along which the hanging wall has moved upward relative to the footwall. Also called a thrust fault.

a semipermeable membrane that will allow water to pass but not salt. Salt water is pressured into the face of the membrane, the water passes through but the salt cannot pass. The filter has be be backwashed regularly to remove the accumulated salt. The pr

n: a device that increases an engines speed by decreasing the positive voltage going to the electric actuator and governor. As the engine needs more fuel to go faster, the reverse-acting actuator decreases the positive voltage to make the governor increase the fuel. Compare direct-acting electric actuator. See governor.

v: to restore production from an existing formation when it has fallen off substantially or ceased altogether. See work over.

n pl: the metal parts (with the exception of nails, bolts, guy wires, and sand lines) used in the construction of a standard cable-tool rig.

n: The metal components be used to make standard cable rig.
