formation binding agents (calcite, clay, silica overgrowth, heavy oil, etc.) that hold the formation grains together.

n: I. the crystallisation or precipitation of soluble minerals in the pore spaces between clastic particles, causing them to become consolidated into sedimentary rock. 2. precipitation of a binding material around grains or minerals in rocks.

the material in the rock between the grains that binds the grains together.

the porosity exponent, m, in the Archie Factor.

n: Installed at the suitable position of casing, used for multi-stage cementation.

an approximate level of rock strength where sufficient cementation is present to allow the rock to remain intact during drilling and production. Often the unconfined compressive strength is greater than 1000 to 1500 psi.

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: A kind of pozzolan cement whose cement/water ratio is higher than nomal
cement slurry used in well cementation.

n: the index including drilling speed,unit yardage cost,well devitation, core recovery,qualification rate of well cementation,production efficiency and so on ,used to idicate the drilling reslut-characters of a well,a rig or a facility qualitatively and qua
