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.

n: a layer of ozone in the atmosphere that forms the Earths main shield against the suns ultraviolet radiation, which in large doses increases the risk of cancer (especially skin cancer and melanoma),health problems, and crop damage.

n: the electro-kinetic portion of the spontaneous potential electriclog curve that can be influenced significantly by the characteristics of the filtrate and mud cake or the drilling fluid that was used to drill the well.

n: a tool joint pin which has been subjected to loading which has caused permanent lengthening of the threaded length of the pin. This condition generally results from excessive torque rather than tensile loads.

n: The permanent extend of the external screw of tool joint,which usually because of the larger torque.

n: the horizontal direction of a formation bed or fault plane as measured at a right angle to the dip.

the compass direction of a feature such as a flood plane or fault.

n: horizontal displacement along a fault plane. The San Andreas fault in California is a strike-slip fault.

a tectonically induced failure of a section of a formation with the result that one block of the formation moves horizontally to the formation.

n: a blowout prevention device consisting of a gland and packing arrangement bolted to the wellhead. It is often used to seal the annular space between tubing and casing.

n: the simultaneous pulling of rods and tubing when the sucker rod pump or rods are frozen in the tubing string.
