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 ...
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 ...
Modern slickline technology embeds fiber-optic lines that can transmit two-way data on real-time temperature, pressure and seismic responses along the length of the slickline. This information allows very precise operations of various down-hole tools, including perforation guns. The benefit of this strategy is greater control of the well.
Well intervention vessel Skandi Constructor. A well intervention, or well work, is any operation carried out on an oil or gas well during, or at the end of, its productive life that alters the state of the well or well geometry, provides well diagnostics, or manages the production of the well.
CITHP – closed-in tubing head pressure (tubing head pressure when the well is shut in) CIV – chemical injection valve CK – choke (a restriction in a flowline or a system, usually referring to a production choke during a test or the choke in the well control system)
The BHA also provides directional survey, gamma, pressure, temperature, and in some cases, petrophysical logs as drilling progresses. The latest generation of advanced Coiled tubing drilling BHAs offer the ability to steer the bit, [ 2 ] enabling the well's trajectory to be corrected in response to the measurements taken by the sensors.
4. New England Patriots – Travis Hunter, CB/WR, Colorado. Talent supersedes need here, as there's no blocker worthy of passing over the draft's most electrifying player.
Well control is the technique used in oil and gas operations such as drilling, well workover and well completion for maintaining the hydrostatic pressure and formation pressure to prevent the influx of formation fluids into the wellbore.
