All wells & their spare parts in the Oil & Gas Industry will require maintenance, repair & replacement. It is at this time that the Well Intervention will begin.
Well Intervention falls into two categories:
- Light Intervention: Technician lowers tool/sensor into the live well when pressure is retained at the surface. Well Service Officers perform the Light Interventions using Slickline, Wireline, or Coiled Pipe. This system allows the Operator to avoid blockages in the well. The Light Intervention also modifies/adapts Downhole Equipment (valves & pumps) & to collect data on downhole pressure, temperature & flow.
- Heavy Intervention: Rig Crew can stop production in formation before making major equipment changes. The Heavy Intervention requires Rig Crew to remove the wellhead & other pressure barriers from the well for full access to the wellbore. This operation requires a Rig to remove & reinstall the wellhead & finishing equipment. The Heavy Intervention is carried out to replace spare parts (pipeline & pump) & to close & leave the original production zone to reconfigure the well to produce from the secondary zone.
