OMNI Circulating valve
The tool is operated by repeatedly cycling the annulus pressure up to a predetermined value and then releasing this pressure.

OMIN Vale is acceptable for the full-opening formation testing in cased hole, oil tube tradition perforation, tube string testing and cycle operation in the conjunction of perforation and full-opening formation testing. It overcomes the shortcomings of some other circulating valve, at a certain position, can use the annulus pressure to operate other tools many times and there is no influence upon the OMNI circulating valve. Because of the ability of opening and closing the well many times, it can carry on acidification and fracturing etc. other well stimulations in the end of the full-opening formation test. Using the valve can make the test program simple and reduce the reconnoitering cost greatly.
OMNI circulating valve has two kinds: 3 7/8″ and 5″. They all can run in subsurface environment which contains acid.
