Well intervention is a operation carried out on an oil or gas well during, or at the end of it productive life that alters the state of the well or well geometry, provides well diagnostics, or manages the production of the well.

Depending upon the operation it is categorized as light or heavy intervention. In light intervention, technicians lower tools or sensors into a live well while pressure is contained at the surface. In heavy intervention, 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. These systems allow operators to minimize the possibility of potential well blockages. Operators also order light interventions to change or adjust downhole equipment such as valves or pumps, or to gather downhole pressure, temperature, and flow data.

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.

Typically, heavy interventions are used to replace parts such as tubing strings and pumps that cannot be retrieved through light interventions. Some heavy interventions are performed to plug and abandon an original producing zone to reconfigure the well to produce from a secondary zone; these operations are known as recompletions.

Coil Tubing
Coil Tubing

Coil Tubing refers to a very long metal pipe, normally 1 to 3.25” 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 [...]

Wireline
Wireline

In the oil and gas industry, the term Wireline usually refers to a cabling technology used by operators of oil and gas wells to lower equipment or measurement devices into the well for the purposes of well intervention, reservoir evaluation, a [...]
