Multi Cycle Circulation Valve OMNI Valve Full Opening Formation Testing Service
Introudction of Multi Cycle Circulating Valve
Multi Cycle Circulating Valve is a full opening and annulus pressure-operated re-closable circulating valve, this kind of circulating valve is the OMNI valve in Halliburton, the valve can be open and closed many times and operated by repeatedly cycling the annulus pressure. The multi cycle circulating valve is acceptable for the formation testing in cased hole, oil tube tradition perforating tube string testing and cycle operation in the conjunction of perforation and full-opening formation testing.

Formation Testing Operation Example of the Multi-cycle circulating valve
In the full-opening formation testing, you can connect the OMNI valve. Before the test, you can test the intensity of the oil tubing. The test ends, you can operate the valve to make it circulate the increasing product fluid in the circulating position and extrude the increasing product fluid in the test position. If requiring extruding the circulating fluid leak ball, you can operate the valve to the circulating position to circulate the circulating fluid leak ball, and then operate the valve to the test position to extrude the circulating fluid leak ball. After the well stimulation, you can operate the valve to the circulating position to wash the well. After the washing, if requiring the flow producing, you can extrude the nitrogen cushion in the circulating position to vent a part of the completion fluid, do so you can economize in pumping and continuous tubing venting, then you can operate the valve to the test position to make the oil and the gas flow. Before lifting the tool, you can operate the valve to the circulating position in order to inverse circulation.
