A procedure for severing pipe stuck in a well by detonating special shaped-charge explosives similar to those used in jet perforating. The explosive is lowered into the pipe to the desired depth and detonated. The force of the explosion makes radiating horizontal cuts around the pipe, and the severed portion of the pipe is retrieved.
Industry:Oil & gas
A granular substance (sand grains, aluminium pellets, or other material) that is carried in suspension by the fracturing fluid and that serves to keep the cracks open when fracturing fluid is withdrawn after a fracture treatment.
Industry:Oil & gas
Special tools or equipment made to be lowered into and retrieved from the well on a wireline, for example, packers, swabs, gas-lift valves, measuring devices.
Industry:Oil & gas
Laboratory analysis of a core sample that may determine porosity, permeability, lithology, fluid content, angle of dip, geological age, and probable productivity of the formation.
Industry:Oil & gas
A fishing tool that uses shaped charges to sever casing, tubing, or drill pipe stuck in the hole. See jet cutoff. Compare chemical cutter.
Industry:Oil & gas
1. in drilling, the string of drill pipe or tubing suspended in a well to which is attached a special tool or device that is used to carry out a certain task, such as squeeze cementing or fishing. 2. in pipeline construction, the string of washpipe that replaces the pilot string in a directionally drilled river crossing. The work string remains in place under the river until the actual pipeline is made up and is ready to be pulled back across the river.
Industry:Oil & gas
A tubular device, usually from 10 to 60 feet (3 to 18 meters) long, run in place of a bit and used to cut a core sample.
Industry:Oil & gas
An assembly, including a carrier and shaped charges, that is used in jet perforating.
Industry:Oil & gas
