an outside annulus, one out from the A annulus, usually production casing x production casing or surface casing. (Note, there may be regional differences in the A, B, C annulus designations)

an outside annulus, next out from the B annulus, usually production casing x production casing or surface casing. (Note, there may be regional differences in the A, B, C annulus designations)

n: The well whose surface casing leaks gas after blowout.

n: a string of casing sets in the borehole to keep the hole from caving and to steal off troublesome formations.

often a casing string or liner run to isolate a zone between the surface casing and the final production casing.

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

n: also called protection casing or technical casing, it is refer to the casing that between the surface casing and production casing, which can content the limitation of the complex layer and the drilling technic.

n: A casing string that is generally set in place after the surface casing and before the production casing. The intermediate casing string provides protection against caving of weak or abnormally pressured formations and enables the use of drilling fluids o

a external annulus ( production by surface casing for example, in which the cement behind the production pipe has not been brought up into the casing by casing annulus. The annulus is open to the formation into which the outer string has been set.

n: a string of casing set deeper than the surface casing to protect a section of the hole and to permit drilling to a greater depth. Sometimes called intermediate casing string.

n: an intermediate string of casing that is run to case off any troublesome zones.

n: also called intermediate casing or technical casing, it is refer to the casing that between the surface casing and production casing, which can content the limitation of the complex layer and the drilling technic.



a string of casing used when drilling a well to protect an outer string of pipe from drill string contact or to protect a zone.
