n: the replacement of cations associated with a clay surface by those of another element, e.g., the conversion of sodium clay to calcium clay.

n: the chemical and physical changes that sedimentary deposits undergo (compaction, cementation, recrystallisation, and sometimes replacement) during and after lithification.

the process of forming a sedimentary rock from the clastic grains. May also be in conjunction with several geochemical processes such as cementation reactions and chemical dissolution.

n: 1. the weight of a fluid (such as water) displaced by a freely floating or submerged body (such as an offshore drilling rig). If the body floats, the displacement equals the weight of the body. 2. replacement of one fluid by another in the pore space of a reservoir. For example, oil may be displaced by water.

n: the mass of fluid displaced by substance floating or sinking in the fluid

n: the shrinking of the solid volume of rock as limestone turns to dolomite, i.e., the conversion of limestone to dolomite rock by replacement of a portion of the calcium carbonate with magnesium carbonate.

n: a kind of toggling tools with rubber or lead material and anchor slip ,usually connected on the lower end of the replacement section

gravel pack replacement

n: the partial displacement using other cation to displace the silicon of tetrahedral coordination and the magnesium or aluminum of octahedral coordination in the clay mineral,
the cation that its character is similar to the displacement .

n: a system of conducting regular checks and testing of equipment to permit replacement or repair of weakened or faulty parts before equipment failure results.

v: to pull a bit from the hole for replacement before it is greatly worn.

n: the act of putting enough drilling fluid in the wellbore to replace the volume of any pipe or other tools that were removed.
