What is well intervention vessel?
marine. A dynamically positioned (DP) ship-shaped offshore unit provided with equipment for well stimulation or maintenance (e.g. coil tubing). Such vessels are often able to carry out other tasks as ROV operations and general supply duties.
What is the difference between well intervention and workover?
The term workover is used to refer to any kind of oil well intervention involving invasive techniques, such as wireline, coiled tubing or snubbing. Practically any offshore supply vessel can swiftly be converted into a well intervention unit without any assessment or approval of the modification of the vessel.
What is intervention in oil and gas?
■ An operation carried out on an oil or gas well to extend its producing life by. improving performance or providing access to stranded or additional. hydrocarbon reserves.
What is a wellhead in oil and gas?
A wellhead is a component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment.
What are well intervention services?
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.
What special equipment is used for an invasive 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. Granherne Inc.
What is well head platform?
Wellhead platform generally is a type of oil platform that houses personnel and machineries to extract oil and natural gas through wells in the ocean bed. A wellhead platform (WHP) may include an integrated deck, utility systems, wellhead systems, helideck and drilling facilities.
What is swab valve?
1. n. [Well Workover and Intervention, Well Completions] The topmost valve on a Christmas tree that provides vertical access to the wellbore.
What is intervention operation?
The intervention procedure should include providing support to the victim of violence, securing evidence and determining the circumstances of the incident, drawing consequences against the perpetrator of violence and working on changing the student’s attitude.
What are workover activities?
The process of performing major maintenance or remedial treatments on an oil or gas well. In many cases, workover implies the removal and replacement of the production tubing string after the well has been killed and a workover rig has been placed on location.
What is a riser platform?
A riser is usually a pipe which connects between a subsea pipeline and the platform topside. The riser pipe can be made from rigid or flexible pipe in the size range from 2″ DIA to 36″ DIA depending 011 requirements. The riser design accommodates substantial environmental loading, particularly ill the splash zone.
What is the well head pressure?
Wellhead pressure – pressure at the top of the well, i.e., at its wellhead. It is measured by pressure gauges of the wellhead fittings. Numerically it equals the difference between reservoir pressure and hydrostatic pressure of the liquid column from wellhead to reservoir.
What is the definition of a well intervention?
Well intervention. 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.
What’s the difference between a well and a wellbore?
What is a Wellbore. A wellbore is a hole that is drilled to aid in the exploration and recovery of natural resources including oil, gas or water. A wellbore is the actual hole that forms the well.
What is the purpose of a wellbore hole?
A wellbore is a hole that is drilled to aid in the exploration and recovery of natural resources including oil, gas or water.
How are wellbores used to extract natural resources?
Resource extraction companies dig wellbores to gain access to the natural resources they are seeking, such as oil and gas. A wellbore is usually a straight vertical shaft that “bores” into the ground to allow the recovery of natural resources. It also includes the open hole and uncased portions of the well.
