v: To apply acids to the wall of oil and gas wells to remove any material that might obstruct flow into the wellbore.

n: Refers to eyeholes formed by mud desander in drilling operation.

the unobstructed opening size (diameter, length and width, or other shape factor).

n: a measuring device installed on the outside of a tank to permit observation of the depth of the liquid inside.

n: the surface that separates each successive layer of a stratified rock from the preceding layer. It is here that minor changes in sediments or depositional conditions can be observed.

a packer or packoff installed at surface on a well that enables the use of one size pipe inside another and allows flow into or out of each pipe separately.

n: a process used to repair a hole in the casing by pumping cement down tubing or drill pipe. First. the casinghead, or bradenhead, is closed to prevent fluid from moving up the casing. Then the rigs pumps are started. Pump pressure moves the cement out of the tubing or pipe and, since the top of the casing is closed, the cement goes into the hole in the casing. The tubing or pipe is pulled from the well and the cement allowed to harden. The hardened cement seals the hole in the casing. Although the term bradenhead squeezing" is still used, the term ,."bradenhead" is obsolete. See annular space. casinghead, squeeze.
