n: The shale sample produced by compaction cell compacting cavy shale under adopting pressure when doing preventing caving test.

n: a decrease in the volume of a stratum due to pressure exerted by overlying strata, evaporation of water, or other causes.

n: The process of breaking cuttings and compacting it into sample with compaction cell when doing preventing caving test.

a crushing of the matrix structure as overburden loads press down on the rock, reducing the pore space. During production of the well, the load on the matrix increases as the pore-filling fluids are removed. These loads may reduce the porosity of the rock

n: see draped anticline.

n: A kind of device that is used to compact different samples.

a drive mechanism in a weak zone that displaces fluid by reducing the overall volume of the formation.

the change in density with increasing depth is often a result of compaction. Age, lithology and porosity modification are also factors.

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: an anticline composed of sedimentary deposits atop a reef or atoll, along whose flanks greater thicknesses of sediments have been deposited and compacted than atop the reef itself. Also called compaction anticline.

dense layer of soil containing silt and sand, but no organic matter and little clay. May have extreme hardness due to compaction.

n: in the process of sediment the fluid in the pores becomes high pressur by the extrusion and the degree of the pore reduce is not much when the permeately layer is surrounded by dense layer.
