A simple slickline tool used to dislodge or push tools or equipment down the wellbore. The blind box is generally of heavy construction and is hardened to reduce damage when jarring is required.
Industry:Oil & gas
A short subassembly used to enable two components with different thread types or sizes to be connected.
Industry:Oil & gas
A simple separator vessel used to remove free or entrained gas from fluids circulated in the wellbore, such as mud used during drilling operations. The gas buster typically comprises a vessel containing a series of baffles with a liquid exit on the bottom and a gas-vent line at the top of the vessel.
Industry:Oil & gas
A short section of plain tubing used to separate or space-out specialized components in a completion assembly. Blank pipe is commonly used in sand control completions where intervals of screen are separated by short sections of blank pipe. The term is also used to describe unperforated sections of casing or liner.
Industry:Oil & gas
A short flow period at the beginning of a drillstem test. This period is followed immediately by a longer shut-in period to allow the pressure to closely approach initial reservoir pressure. The initial flow period is commonly 5 to 10 minutes, and the initial shut-in period is commonly 30 minutes to one hour. When plotted on a pressure buildup plot, extrapolation of the best straight line gives what is usually accepted as the best obtainable value of initial formation pressure.
Industry:Oil & gas
A short piece of brass or steel that is used to retain sliding components in a fixed position until sufficient force is applied to break the pin. Once the pin is sheared, the components can then move to operate or function the tool.
Industry:Oil & gas
A ship designed to transport crude oil, liquefied petroleum gas (LPG), liquefied natural gas (LNG), synthetic natural gas (SNG) or refined products. Tankers with 100,000 deadweight tons of capacity or more are called supertankers (very large crude carriers or ultralarge crude carriers). A tanker is also called a tank ship.
Industry:Oil & gas
A short crossover joint used between two sizes or specifications of casing. A circulating swage is an adapter that enables a temporary circulating line to be rigged to the top of the casing string, allowing circulation of fluids to help properly locate the casing string.
Industry:Oil & gas
A short drillstring component that is temporarily connected to the top of a tool assembly that is to be lifted vertically, such as when running or retrieving a tool string. The external profile on the upper section of the lifting sub is similar to that of the completion tubing, enabling the rig elevators to lift the assembled tool string safely.
