Hydraulic jars for slickline are generally meant to jar up only, because not enough sinker bar is able to feasibly be lubricated in to jar down on the downhole tools. Hydraulic jars work by the operator pulling up on the line, which puts an upward force on the top of the hydraulic jars. The bottom of the hydraulic jars is usually attached by ...
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 ...
Wireline truck rigged up to a drilling rig in Canada. In the oil and gas industry, the term wireline usually refers to the use of multi-conductor, single conductor or slickline cable, or "wireline", as a conveyance for the acquisition of subsurface petrophysical and geophysical data and the delivery of well construction services such as pipe recovery, perforating, plug setting and well ...
Coiled tubing umbilicals can convey hydraulic submersible pumps and jet pumps into wells. These pumps allow for inexpensive and noninvasive well cleanouts on low-pressure CBM (coal bed methane) gas wells. These umbilicals can also be run into deviated wells and horizontal laterals.
This engagement occurred when the cross-heads came together. Today, there are two primary types, hydraulic and mechanical jars. While their respective designs are quite different, their operation is similar. Energy is stored in the drillstring and suddenly released by the jar when it fires. Jars can be designed to strike up, down, or both.
There are three types of packers: mechanical and hydraulic set and permanent. All packers fall into one or a combination of these. Mechanical set packers are set by some form of tubing movement, usually a rotation or upward /downward motion. Others can be weight set—the tubing weight can be used to compress and expand the sealing element.
Wireline may refer to: . Slickline, a cabling technology used for oil-well completions and maintenance; Wireline (cabling), a cabling technology involving sending a current to downhole logging tools in oil-well exploration and completions
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 ...
