Dual Cycle Valve.

The Omega Dual Cycle valves are permanently installed, electronically actuated sleeve type valves which allow for two cycles (closed, open, closed or open, closed, open)

The onboard electronics require no connection to surface. The valves may be programmed to function upon the expiry of a pre-determined time delay, or alternatively by using Omega “PROLOGUE” pressure recognition technology. In addition, a combination of both the above methods may also be utilised. The valves are typically installed in a wellbore with isolation packers above and below in order to provide zonal control and isolation.

Multiple valves can be deployed in one well with differing programmes. Single or multiple zones may be open or closed allowing a well to be tested, flowed or fractured depending on the application. Use of this technology has been proven to increase the productivity of less productive zones and overall well clean up. This also improves the drainage and overall recovery from the well.

The valves are typically run in the closed position and will open once initiated. Sending a further command to the valve will close the valve again. Each Dual Cycle valve features two independent electronics sections either of which can provide the actuation for the device. The electronics are easily programmed from a laptop computer running “Windows” style software and may be set up at the wellsite.

Contingency exists to open or close the valves at any time utilizing conventional wireline techniques to mechanically shift the valves to the open or closed position.

The Prologue range of valves build on the same field proven technology currently available in products such as the Clean Out Valve, Tracer Deployment Valve, Self-Opening Sandface Valve and Command Activated Sandface Valve.
