摘要： A well bore fluid recovery system and method is disclosed for recovering a column of well bore fluid within a stand of casing before cutting the casing. The recovery system relates to a system for preventing fluids from being spilled when casing is being finished for a well bore. After being run the casing must be cut and finished at an appropriate level to install rig equipment such as blow out preventers along with other equipment. However, because of earlier operations, the entire length of casing is typically filled with drilling fluid. Depending on conditions, the length of casing which is to be cut and removed may therefore over a 100-foot (27.4 meter) column of drilling fluid therein. The drilling fluid in this section must be properly drained before the casing is cut and removed.

摘要： A method and apparatus for removing a string of casing from a well bore. The method and apparatus include a plurality of drill bits substantially aligned with each other for drilling a plurality of holes in the string of casing. The plurality of holes can be used to lift the string in casing from the well bore via a series of incremental casing sections.
