n: 1. the part of the surface equipment of a standard cable-tool drilling rig that supports the walking beam. 2. the member of a rod pumping unit that supports the walking beam.

n: 1. an abrasive material composed of small quartz grains formed from the disintegration of preexisting rocks. Sand consists of particles less than 2 millimetres (0.078 inches) and greater than 1/16 millimetre (0.062 inches) in diameter. 2. sandstone.

n: an abrasive material composed of small quartz grains. The particles range in size from 1/16 mm to 2 mm.the term is also applied to sandstone.

specifically a sandstone, but also used in some texts as a general term for the pay zone.

a slickline tool used to place or remove sand or similar small grains from a wellbore.

n: a device used to remove sand from the wellbore. It sucks up sand by creating a partial vacuum and traps the sand by closing at the bottom.

n: anyone of several methods by which the loose, unconsolidated grains of a producing formation are made to adhere to prevent a well from producing sand but pemlit it to produce oil and gas.

one of various methods of consolidating the grains of an unconsolidated or weakly consolidated formation. Typically resin consolidation (epoxy, furan or phenol-formaldehyde),but may also include sodium silicate, coking, and mineral or metal precipitates.

n: the insoluble abrasive solids contents of a drilling fluid rejected by a 200-mesh screen. Usually expressed as the percentage bulk volume of sand in a drilling fluid. This test is an elementary type in that the retained solids are not necessarily silica and may not be altogether abrasive. For additional information concerning the kinds of solids retained on the 200-mesh screen, more specific tests would be required. See mesh.

n: The percentage of sand that cannt through the screen of 200 eye in the drilling fluid.

n: any method by which large amounts of sand in a sandy formation are prevented from entering the wellbore. Sand in the wellbore can cause plugging and premature wear of well equipment. See gravel pack, sand consolidation, screen liner:

one of various mechanisms for controlling formation sand movement during fluid production from a weakly consolidated sandstone.

a sand restraining device that is a mesh or wire wrapped screen wound over a base pipe with holes.
