n: The process in which the bit continually breaks the formation and deepend the wellbore. It is controled by the driller who operates the brake crank and set down the drilling string to keep definite weight on bit.

n: The process that Record the data of drill fluid, drill speed, core sample and gas surveying in order to know the formation in the deepening of well.

n pi: special conditions or additional requirements that are attached to permits to drill, deepen, or plug back. These conditions range from administrative matters, such as the frequency and number of required reports, to technical or environmental conditions, such as requirements for drilling mud disposal. In all cases, these are specific conditions that amplify or explain a requirement in OCSLA, MMS regulations, OCS Orders, or lease stipulations.

n: The method of equiping slurry that make sure the density of cement slurry broaden with the well deepening by equiping cement slurry with same ratio of gas and slurry.

v: to increase the depth of a well. Deepening is generally a workover operation carried out to produce from a deeper formation or to control excessive gas found in the upper levels of a reservoir.

n: Increasing depth of wellbore. Usually it is a workover operation.

v: 1. to remove with the bit the residual cement that normally remains in the lower section of casing and the wellbore after the casing has been cemented.2. to remove the settlings and cavings that are plugged inside a hollow fish (such as drill pipe) during a fishing operation.

drilling through the cement after a primary cement job as the hole is deepened.

n: the string of casing set in a well after the surface casing but before production casing is set to keep the hole from caving and to seal off troublesome formations. In deep wells, one or more intermediate strings may be required. Sometimes called protection casing.

n: A length of pipe used below the surface casing string, but before the production casing is run, to isolate one or more zones of the openhole to enable deepening of the well. There may be several intermediate casing strings. Depending on well conditions, t

v: to attach a joint of drill pipe onto the drill stem suspended in the well bore to permit deepening the wellbore by the length of the joint (usually about 30 feet, or 9 metres).

n: the procedure that add the single to the volume and make the volume extension.

v: to deepen the hole made by the bit, i.e., to drill ahead.

v: to drill ahead.

drill.

n: during deepen the hole, people records tri-relationship of the bit pressure, revolution or drilling speed.
