RFID Circulation Sub maximizes deepwater operations efficacy.

Press Release Summary:

Promoting higher flow rates and cleaner wellbores, JetStream® enables operators to run series of tools at different positions along drillstring and remotely actuate valves for unlimited number of times in one trip in deep water. RFID technology, by enabling selective opening and closing of tools at different points, provides options for cleaning wellbore, spotting lost-circulation material (LCM) and kill-weight fluids, as well as jetting blowout preventer (BOP).

Circulation Sub Maximizes the Efficiency of Deepwater Operations by Providing Higher Flow Rates, Better Hole Cleaning, and Superior Operational Flexibility

Weatherford announces the release of JetStream® RFID circulation sub

HOUSTON – Weatherford International plc announced today the commercial release of JetStream® Radio Frequency Identification (RFID) circulation sub at the Annual Technical Conference and Exhibition. 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. 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.

"Weatherford has pioneered the innovative application of RFID technology in the oil and gas industry to drive operations efficiency," said Neil Gordon, Vice President of Intervention Services and Drilling Tools at Weatherford. "As operators deal with more complex wellbores, the ability to drop an RFID tag from the surface and circulate it through the sub enables our clients to open and close downhole tools multiple times, which provides superior operational flexibility and saves days of rig time. In deepwater drilling operations, RFID technology can save the client over $1 million per application by reducing the amount of non-productive time. This is critical in the current economic environment."

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.
