v: to cease producing oil and gas from a well when it becomes unprofitable or to cease further work on a newly drilled well when it proves not to contain profitable quantities of oil or gas. Several steps are involved: part of the casing may be removed and salvaged;one or more cement plugs are placed in the borehole to prevent migration of fluids between the different formations penetrated by the borehole;and the well is abandoned. In most oil-producing states, it is necessary to secure permission from official agencies before a well may be abandoned.

to cease efforts to produce or inject fluids in a wells and to plug the well sufficiently to protect the environment and the ability to redrill and develop other reserves at a later date.

n: The diameter of the drilled wellbore. The borehole diameter can change greatly even the same bit due to the change of formation lithology and formation collapse.

n: the well bore which has been drilled and probed

n: the number of well out of which the drilling bit is pulled when drill to the intended zone

n: the degree of superior and inferior of the drilled wellbore ,mainly including the wellbore quality ,core recovery, cement job quality and complete quality

n: a directionally drilled well that has a high degree of deflection.

n: the accumulate footage of the drilled well in certain time frame

n: a high rate of flow from a newly drilled well.

the early, higher rate production that comes from the larger pores, fractures and vugs that empty quickly. Delivers a small, high rate flow every time the well is shut-in (recharges) and is brought back on line.
