n: an integral part of a blowout preventer. which serves as the closing element on an open hole. Its ends do not fit around the drill pipe but seal against each completely. See ram.

n: a blowout preventer in which blind rams are the closing elements. See blind ram.

The ram sections in a BOP that are used to close against each other and isolate the well when no pipe is in the well.

n: refer toblind ram

n: see blind ram.

n: the closing and sealing component on a blowout preventer. One of three typesblind, pipe, or shear-may be installed in several preventers mounted in a stack on top of the wellbore. Blind rams, when closed, form a seal on a hole that has no drill pipe in it;pipe rams, when closed, seal around the pipe;shear rams cut through drill pipe and then form a seal.

n: the closing assembly which packs the whole well or the annular space out of the drilling pipe and controls the blowout,usually consist of rubber wick,brake body ,cover plate and screws

one of the hydraulically actuated rams in a blow out preventer (blind, shear, pipe or slip).

n: A type of vertical seismic profile in which the source is a shear-wave source rather than a compressional-wave source. Shear waves travel through the Earth at about half the speed of compressional waves and respond differently to fluid-filled rock, and so

a set of pipe seal and blind rams used in the snubbing operation.
