What is well intervention system?
What is well intervention? Well intervention is the ability to safely enter a well with well control for the purpose of doing a number of tasks other than drilling. Well intervention historically was done with drill rigs, with an 18-3/4” BOP and 21” marine riser as the only means of well access with well control.
What is well intervention workover?
Well workover refers to any kind of oil and gas well intervention involving invasive techniques, such as wireline, coiled tubing, or snubbing.
Why do we need to perform well intervention?
With over 5,000 oil and gas wells globally, well intervention is used to extend the life of wells and keep up with the rising demand for oil and gas. All oil and gas wells require maintenance over time, and well intervention helps repair damaged and underperforming wells.
What is well intervention vessel?
Our well Intervention vessels provide subsea well intervention solutions on oil or gas wells, in order to increase production. The vessels have been designed to minimize production downtime and to provide cost effective well maintenance, production enhancement and well abandonment solutions.
What are the three common types of wireline used in well intervention?
Well service personnel typically perform light interventions using slickline, wireline, or coiled tubing.
What is offshore well intervention?
■ 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 wireline well intervention?
Wireline services consist of various well intervention functions that are accomplished under pressure by “running” and “pulling” tools into and out of the wellbore by the use of a continuous length, small diameter wire mounted on a powered reel at the surface.
What type of intervention activities are conducted in the well?
Downhole operations performed during well intervention jobs include well surveillance and diagnosis, implementation of reservoir management techniques, completion repair, and re-entry drilling to reach new producing intervals.
What are light interventions in oil well maintenance?
During light interventions, technicians lower tools or sensors into a live well while pressure is contained at the surface. In heavy interventions, the rig crew may stop production at the formation before making major equipment changes. Well service personnel typically perform light interventions using slickline, wireline, or coiled tubing.
What are the different types of well interventions?
At some point in the life of all oil and gas wells, parts will require maintenance, repair or replacement. At these times, operators turn to intervention specialists. Interventions fall into two general categories: light or heavy.
What does an intervention specialist do?
At these times, operators turn to intervention specialists. Interventions fall into two general categories: light or heavy. During light interventions, technicians lower tools or sensors into a live well while pressure is contained at the surface.
What is a heavy intervention in oil drilling?
Heavy interventions—also referred to as workovers—require the rig crew to remove the wellhead and other pressure barriers from the well to allow full access to the wellbore. These operations require a rig to remove and reinstall the wellhead and completion equipment.
