Drilling & Workover Rigs

GF Balance Overseas’s fleet of rigs range from 200 HP to 1,500 HP and offer drilling capabilities for all type of wells with depths up to 4000m. Our fleet includes 750 HP truck mounted, fast moving rigs which are ideal for both light and heavy work over campaigns as both rigs are equipped with full edge mud system that can handle normal drilling activities.

We continuously update our modern fleet of land drilling rigs through investment and application of the latest technology. Our rigs are equipped with the most advanced equipment available and this combined with our experienced drilling team makes GF Balance Overseas the best choice for drilling and work over projects.


  • Oil and Gas Well Drilling Operations
  • Oil and Gas Well Work Over Operations
  • Water Well Drilling Operations

Equipment and Resources:

  • Oil Well Rigs
  • Workover & Water Well Rigs

The following are common workover tasks that we perform.


  • Subsurface pumping. Subsurface pumps are required in the vast majority of the onshore oil producing wells in Russia. These pumps have a finite life and are routinely replaced, on average, every 12 months.
  • Remedial cementing. Frequently, cementing operations are carried out on existing wells to shut off water or unwanted gas production.
  • 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.
  • Re-completion. Downhole completion hardware is exposed to materials such as corrosive water, sand, scale, tar and wax which can clog and damage equipment. Re-completing a well may mean extracting the hardware and repairing or replacing it, in part or in its entirety. Alternatively, as downhole well conditions change over time (as a result of increased levels of watercut, for example) or as technology improves, different tools may be used or artificial lift hardware may be employed (such as electrical submersible pumps). Wells are often re-completed in different zones to enhance production.
  • 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
