2. Coiled tubing - Wikipedia

   en.wikipedia.org/wiki/Coiled_tubing

   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 ...

3. Internally grooved copper tube - Wikipedia

   en.wikipedia.org/wiki/Internally_grooved_copper_tube

   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 ...

4. Copper tubing - Wikipedia

   en.wikipedia.org/wiki/Copper_tubing

   Rigid copper is a popular choice for water lines. Rigid or "Hard" copper tubing is generally referred to as "pipe". Copper "piping" is referred to by nominal pipe size, or the inner diameter. It is joined using a solder/sweat, roll grooved, compression, or crimped/pressed connection. Rigid copper, rigid due to the work hardening of the drawing ...

5. Snubbing - Wikipedia

   en.wikipedia.org/wiki/Snubbing

   Snubbing is a type of heavy well intervention performed on oil and gas wells. It involves running the BHA on a pipe string using a hydraulic workover rig. Unlike wireline or coiled tubing, the pipe is not spooled off a drum but made up and broken up while running in and pulling out, much like conventional drill pipe.

6. Coiled tubing drilling - Wikipedia

   en.wikipedia.org/wiki/Coiled_tubing_drilling

   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 ]

7. Capacitor discharge ignition - Wikipedia

   en.wikipedia.org/wiki/Capacitor_discharge_ignition

   Capacitor discharge ignition. CDI module. Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine -powered aircraft, and some cars. It was originally developed to overcome the long charging ...

8. Pipe recovery operations - Wikipedia

   en.wikipedia.org/wiki/Pipe_recovery_operations

   Pipe recovery is a specific wireline operation used in the oil and gas industry, when the drill string becomes stuck downhole. Stuck pipe prevents the drill rig from continuing operations. This results in costly downtime, ranging anywhere from $10,000-1,000,000 per day of downtime, therefore it is critical to resolve the problem as quickly as ...

9. Copper in heat exchangers - Wikipedia

   en.wikipedia.org/wiki/Copper_in_heat_exchangers

   Heat exchangers using copper and its alloys have evolved along with heat transfer technologies over the past several hundred years. Copper condenser tubes were first used in 1769 for steam engines. Initially, the tubes were made of unalloyed copper. By 1870, Muntz metal, a 60% Cu-40% Zn brass alloy, was used for condensers in seawater cooling.
