n: The resistivity recorded by electrical logging. It is different from the real resistivity due to the influence of cake, invaded zone and surrounding rock.

resistivity recording where the measured value differs from the true or defined state by the influence of the mud column, invasion of a zone by fluids, or wellbore anomalies.

n: false influence on well logging measurement caused by the borehole environment, e.g., diameter, shape, rugosity, type of fluid, or mud cake.

n: The distortion of borehole log due to the change of diameter and shape of wellbore or drilling fludi invasion.

n pi: obtained by collecting the chips made by boring holes with a ship material contained in a barrel, case, bag, or cake.

n: The solid particle that forms cake in the borehole face or formation pore.

n: see filter cake.

n: A tier of penetrant medium adhering to the borehole face in the filtration process of solid phase of drill fluid.

filter or mud cake, stranded by dehydration on the face of a permeable formation by fluid loss.

n: the character or state of the drilling mud filter cake. According to API RP I3B, such notations as hard," "soft," "tough," "rubbery," and "firm" may be used to convey some idea of cake consistency.

n: The character of compact degree in the condition that the cake is pressed.

n: According to API RP 13B, such notations as hard, soft, tough, rubbery, firm etc., may be used to convey some idea of cake consistency.

n: The hard or easy degree that cake deposited in the borehole face is eroded by drill fluid.

n: A very important target. The lower the filter loss of drill fluid, the more steady the borehole face is.
