Weatherford International, with corporate offices in North and South America, recently announced the release of the JetStream® Radio Frequency Identification (RFID) circulation sub for deepwater applications in the oil & gas industry. The JetStream RFID circulation sub enables operators to run a series of tools at different positions along the drillstring and remotely actuate the valves an unlimited number of times in a single trip to achieve higher flow rates and cleaner wellbores.
Poor wellbore integrity can cause events such as stuck pipe, wellbore collapse, sloughing shales and lost circulation, which are major concerns for drillers in deep water. Recently an operator drilling in the North Sea deployed the JetStream RFID circulation sub in a 6.5-inch intermediate section that was drilled to total depth of 10,446 feet through a soft, porous limestone formation. The JetStream RFID circulation sub was actuated a total of 16 times to spot 29 lost-circulation material pills, which allowed the operator to maintain loss rates below 20 bbl/hr (3 m(3)/ hr) and avoid abandoning the well.
