n: Refers to the carbon dioxide bullet used as the pressure origin of filter press of drill fluid.

n: 1. compacted solid or semisolid material remaining on a filter after pressure filtration of mud with a standard filter press. Thickness of the cake is reported in thirty seconds of an inch or in millimetres. 2. the layer of concentrated solids from the drilling mud or cement slurry that forms on the walls of the borehole opposite premeable formations;also called wall cake or mud cake.

n: (1) The soild residue deposited by a drilling fluid against a porous medium, usually filter paper, according to the standard API filtration test. (2) The soild residue deposited on the wall of a borehole during the drilling of permeable formations.


the layer of solids stranded on the face of permeable formations by liquids driven into the rock by pressure differential towards the formation. When sized correctly the filter cake may completely stop losses.

n: a device used in the testing of filtration properties of drilling mud. See mud.

n: A device for determining fluid loss of a drilling fluid having specifications in accordance with API RP 13B.

usually at DE filter.

n: the pressure imposed when take an experiment about fluid loss

n: the area of valid filter medium in filter press when take an experiment about fluid loss

n: the area of valid filter medium in filter press when take an experiment about fluid loss

n: a component in HPHT filter press,used to store high-temperature filter and prvente the filter being evaporated
