Coiled Tubing Unit (CTU) In the oil and gas industry, coiled tubing refers to a long metal pipe, normally 1 to 3.25 in (25 to 83 mm) in diameter which is supplied spooled on a large reel. It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Coiled tubing is often used to carry out ...
Coiled Tubing Drilling (CTD) is a drilling method that combines coiled tubing and directional drilling. [ 1 ] [ 2 ] It uses a mud motor to create a system for reservoirs. [ 3 ] [ 4 ]
Internally grooved copper tubes, also known as "microfin tubes", are a small diameter coil technology for modern air conditioning and refrigeration systems. Grooved coils facilitate more efficient heat transfer than smooth coils. [ 1 ][ 2 ] Small diameter coils have better rates of heat transfer than conventionally-sized condenser and ...
Wireline truck rigged up to a coil tubing unit in order to cut the coil tubing. Differentially Stuck Pipe. The geological formation downhole occasionally has a significantly lower pressure than the drilling fluid being used. When the pipe string comes into contact with the exposed formation the difference in pressure will cause the pipe to be ...
Condenser (laboratory) A distillation setup using a Liebig-type condenser (the tilted double-walled tube at the center). A liquid (not visible) in the flask at left is heated by the blue mantle to the boiling point. The vapor is then cooled as it goes through the inner tube of the condenser. There it becomes liquid again, and drips into the ...
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 condenser is designed to transfer heat from a working fluid (e.g. water in a steam power plant) to a secondary fluid or the surrounding air. The condenser relies on the efficient heat transfer that occurs during phase changes, in this case during the condensation of a vapor into a liquid. The vapor typically enters the condenser at a ...
PowerPoint for the web is a free lightweight version of Microsoft PowerPoint available as part of Office on the web, which also includes web versions of Microsoft Excel and Microsoft Word. PowerPoint for the web does not support inserting or editing charts, equations, or audio or video stored on your PC, but they are all displayed in the ...
