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 holding of formation rock chips in place as a result of high differential pressure in the wellbore (i.e., pressure in the wellbore is greater than pressure in the formation). This effective- its the cutting action of the bit by retarding circulation of bit cuttings out of the hole.

n: See cuttings.

n pI: the fragments of rock dislodged by the bit and brought to the sulphur in the drilling mud. Washed and dried cuttings samples are analysed by geologists to obtain information about the formations drilled.

n: Small pieces of rock, cement, or steel that break away due to the action of the bit, milling, cutting, or underreaming tools.

chips of rock from the drilling process. They are circulated to the surface by the mud and separated in the screens and shaker. They are useful for identifying and correlating the formation.

the small chips and fines generated by drilling through a formation with a drill bit. Most of the cuttings are removed from the mud as the fluid pass through the solids control equipment (e.g., shakers, screens, cyclones, etc.,) at the surface.

n: the difference between the indications of a measuring instrument when the same value of the quantity measured is reached by increasing or decreasing the quantity.

n: the phenomenon that the chips of rock lags flute in the reture when drilling.

v: to break off in chips or scales, as on a plain, or journal, bearing.

v: A kind of borehole collapse .clumpy or pieces of rock fall in the hole .
