Timer Activated Sandface Valve


  • Field proven electronics.
  • Delayed opening for up to 150 days.
  • Top selective profile for pressure control accessories.
  • Defaults to mechanical sleeve.
  • Utilises existing wireline / intervention procedures when mechanically actuated.
  • Large flow areas.
  • Multiple valves in one well.


  • Increased production due to better contribution from minor zones.
  • Increased production from improved recovery.
  • Increased production from subsequent water shut off.


  • Delay start up of prolific zones.
  • Isolate laterals to allow staged start up.
  • Water shut off after start up.
  • Test individual zones following start up or during start up.

Technical Specifications

The Omega Timer Activated Sandface Valve (TA-SFV) is a permanently installed electronically actuated sleeve type valve which is run in the closed position and which will open following the expiry of a pre programmed delay period.

The TA-SFV is installed in a wellbore with isolation packers above and below in order to provide staged start-up of a producer well without the requirement for intervention. Good production sections may be isolated allowing less prolific areas to clean up preferentially. Following the pre-determined delay time, the TA-SFV will function and open allowing all sections to flow and clean up. Use of this technology should improve productivity of the less productive zones and overall well clean up. This will result in an increase of overall productivity for the lifetime of the well.

Multiple tools may be run in one well with differing start up times.

The TA-SFV activation timer features two electronic units, which are totally independent of each other for full redundancy. Each independent electronic unit is programmed via the comms port on the valve upper housing. The electronics are programmed from a laptop computer running “Windows” style software.

Contingency exists to open the valve utilizing conventional wireline techniques to mechanically shift the valve to the open position.

The TA-SFV uses the same field proven technology currently used in products such as the Clean Out Valve and Tracer Deployment Valve. These products have all been developed from our original Addressable Completion Accessory Tool (ACAT) technology.

Time Delay Equalizing Valve

Provides a removable barrier in situations where no intervention, or communication means are possible.


"I am hesitant in passing on all of the good things about Versa-Line due to the possibility that if other operating company's personnel find out, I will have a hard time securing services from them in the future. Versa-Line provides top notch service and equipment at very reasonable pricing. I have used Versa-Line several times in different application in production maintenance and production optimization operations and have never had a bad day. Their personnel are not only experienced and good at what they do, they are also eager to please and a joy to work with. They take their customer's needs very seriously. In my opinion, Versa-Line is the top in the industry for plunger lift fishing and trouble shooting."
