What is coil tubing in oil and gas?
In the oil and gas industries, coiled tubing refers to a very 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.
What is Rigless operation in oil and gas?
1. n. [Well Completions] A well-intervention operation conducted with equipment and support facilities that precludes the requirement for a rig over the wellbore. Coiled tubing, slickline and snubbing activities are commonly conducted as rigless operations.
What is snubbing in trucking?
Drivers must avoid this situation by snubbing – applying the brakes hard enough to slow the vehicle at the gentle rate typical of pulling up to a traffic light, rather than just holding a steady speed. This means losing 5 to 6 mph in about three seconds and then releasing the brakes until the speed has been regained.
Is coil tubing a good job?
Great Money but at a great cost to you and your family Tough lifestyle and its hard on your family but the compensation is worth it when oil prices are high. This company is the best coil tubing company out there by far so if you get into i would recommend you go with coil tubing partners.
What is Rigless operation?

What is radial drilling in oil and gas?
Radial/Jet drilling involves jetting lateral holes of approximately 50 mm diameter up to 100 m laterally from the well bore by jetting high pressure fluid using micro-CTU. Lateral bores can be jetted at single or multiple layers.
What is workover rig?
Workover rig means a mobile self-propelled rig used to perform one or more remedial operations, such as deepening, plugging back, pulling and resetting liners, on a producing oil or gas well to try to restore or increase the well’s production.
What is workover operation?
A workover is any operation done on, within, or through the wellbore after the initial completion. Although proper drilling, cementing, and completion practices minimize the need, virtually every well will need several workovers during its lifetime to satisfactorily fulfill its purpose.
What is a snubbing supervisor?
Supervisor – Snubbing A demonstrated knowledge of the function and location of all snubbing unit operating controls. The Snubbing Supervisor is responsible for coordinating and overseeing the snubbing service line work at…
What does a coiled tubing operator do?
Coiled tubing operators must be able to transport equipment to and from the well location, safely rig in and operate the equipment, perform day-to-day inspections, servicing and maintenance of equipment, and complete all required paperwork accurately and on time.
What does a coil tubing rig do?
Coiled tubing applications include drilling operations, hydraulic fracturing, well completions, removing sand or fill from wellbore, and other applications that involve pumping fluids at high temperatures and high salinity.
What is Rigless drilling?
What is radial drilling?
Definition of radial drill : a drilling machine with the drill spindle in a toolhead and saddle that are movable along a projecting arm which itself can be rotated about a vertical column.
What is a rigless well intervention?
Rigless techniques for well intervention are wireline, coiled tubing (CT) and hydraulic workover (HWO) services that do not require the use of a conventional workover rig and have the capability of performing downhole applications in live (under pressure) wells.
What tools are used in a workover rig?
A conventional workover rig comprising a derrick, rotary table, and heavy machinery can be used to perform well intervention. However, mobilizing an offshore rig and its associated support operations is expensive. Downhole there is little difference in the tools that are deployed for dry (platform) wells versus subsea wells to remedy flow problems.
Who is this rigless well management course for?
Invaluable for all personnel that are involved in the “Well Life Cycle” and require to have a working knowledge of Rigless interventions. Designed for professionals in the oil & gas industry who are involved in the design, construction and operation of wells from the following disciplines:
What is a rig assist unit?
Hydraulic rig assist units assist conventional workover rigs and supplement the work performed by rigs to make the intervention job much more economical. By definition a rig assist unit is not a stand-alone type unit and operates only in conjunction with the workover rig
