Weatherford RFID technology helps oil and gas firms with drillstring maintenance
October 6, 2015
Weatherford has released the JetStream RFID circulation sub to let oil and gas operators 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.
"Weatherford has pioneered the innovative application of RFID technology in the oil and gas industry to drive operations efficiency," said Neil Gordon, vice president at Switzerland-based 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 deep-water drilling operations, RFID technology can save the client over $1m 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 16.5cm intermediate section that was drilled to total depth of nearly 3200m through a soft, porous limestone formation. The sub was actuated 16 times to spot 29 lost-circulation material pills, which allowed the operator to maintain loss rates below 3m3/hr and avoid abandoning the well.
Weatherford is one of the largest multinational oilfield service companies providing technology and services to the oil and gas industry. The company operates in more than 100 countries, has a network of approximately 1350 locations, including manufacturing, service, research and development, and training facilities, and employs approximately 44,000 people.
