Slickline is more commonly used in production tubing. The wireline operator monitors at surface the slickline tension via a weight indicator gauge and the depth via a depth counter 'zeroed' from surface, lowers the downhole tool to the proper depth, completes the job by manipulating the downhole tool mechanically, checks to make sure it worked if possible, and pulls the tool back out by ...
A jar is a rigid, cylindrical or slightly conical container, typically made of glass, ceramic, or plastic, with a wide mouth or opening that can be closed with a lid, screw cap, lug cap, cork stopper, roll-on cap, crimp-on cap, press-on cap, plastic shrink, heat sealed lidding film, an inner seal, a tamper-evident band, or other suitable means.
Hydraulic energy provides power to mud motor for bit rotation and for MWD (measurement while drilling) and LWD (logging while drilling) tools. Hydraulic programs base on bit nozzles sizing for available mud pump horsepower to optimize jet impact at bottom well. Limited to: Pump power; Pressure loss inside drillstring; Maximum allowable surface ...
After locating the sliding sleeve, the operator jars downward to set the lock, then pulls upward to close the isolation plug in the separation tool. As this happens, a garter spring in the isolation plug moves a steel shear pin into a groove on the sealing prong, and an O-ring on the internal prong seals to isolate the tubing below the sliding ...
Jars rely on the principle of stretching a pipe to build elastic potential energy such that when the jar trips it relies on the masses of the drill pipe and collars to gain velocity and subsequently strike the anvil section of jar. This impact results in a force, or blow, which is converted into energy.
The Kilner Jar was originally invented by John Kilner (1792–1857) and associates, [4] and made by a firm of glass bottlemakers from Yorkshire called Kilner which he set up. [5] The original Kilner bottlemakers operated from 1842, when the company was first founded, until 1937, when the company went into liquidation.
The Ball Brothers' jars, which were produced in half-gallon, pint, and midget sizes, were manufactured during 1884, 1885, and 1886. “Buffalo” jar lids were produced in a Ball Brother metal fabricating factory. The brothers decided to add their logo onto the surface of the glass jars, which were amber or aqua (blue-green) at the time. [3 ...
A bell jar is a glass jar, similar in shape to a bell (i.e. in its best-known form it is open at the bottom, while its top and sides together are a single piece), and can be manufactured from a variety of materials (ranging from glass to different types of metals). Bell jars are often used in laboratories to form and contain a vacuum.
