Time Delay Equalising Valve:
The Omega Time Delay Electronic Equalising Valve (TD-EV) is a time delay based device, which is run below a Packer, Bridge Plug, or Lock Mandrel. Its function is to provide a removable barrier in situations where no intervention, or communication means are possible.
Its main application is to provide a removable barrier during the construction of a multilateral well. The valve would be installed in the main bore below the whipstock, providing a barrier and protecting the reservoir section of the main bore. Once the lateral bore has been drilled and completed and a communication path has been perforated across the whip stock face, the time delay will expire allowing the contained reservoir fluid to flow up through the valve and commingle with the lateral.
Once opened the valve is mechanically locked in the open position.
The Valve contains two independent sets of electronics and two pilot valve mechanisms for 100% redundancy. The time delay can be set up to a maximum of 150 days and is fully programmable on site.
