Workover & Well Servicing

  •     Tubing replacement. Most workovers require the production tubing string to be pulled from the well. As a result, production tubing needs to be replaced as part of the workover process.
  •     Well cleanout. This entails the removal of debris, sand, scale and organic materials from a well to improve the flow of hydrocarbons to the surface. Many reservoirs produce sand that is not carried to surface by the flow of hydrocarbons during production. The resulting accumulations can decrease production and are cleaned out periodically.
  •     Additional perforations or re-perforation. In certain oilfields it is possible to perforate additional intervals in hydrocarbon bearing reservoirs to increase production rates. In other reservoirs it may be possible to re-perforate an existing perforated interval that has become closed. New technologies also allow for deeper penetrating perforating charges.
    Our workover services are carried out by professionist personnel who can complete all works according to international standards.
AlMarooj offers its onshore integrated workover services to local oil and gas companies primarily in Yemen.
A workover is the process of maintaining, repairing or enhancing production from a well through various means. Most workovers require the production tubing string to be pulled from the well by the workover rig in order to repair the defects that may be causing sub-optimal well production. The production tubing is inserted back into the well once the defects have been repaired. In some cases, a workover is performed in order to carry out hydrofracking and acidizing.
The following are common workover tasks that we perform.
  •     Subsurface pumping. Subsurface pumps are required. These   pumps have a finite life and are routinely replaced.
  •     Remedial cementing. Frequently, cementing operations are carried out on existing wells to shut off water or unwanted gas production.
