Schlumberger introduces on-demand Rhino XC reamer to save rig time

Rhino XC has been run offshore Norway by an undisclosed Schlumberger client, the firm said, where a 9,283 ft run was completed in a personal record of 300 circulating hours by adjusting the pump flow rate

Schlumberger has launched a next-generation on-demand reamer providing unlimited activation of the flow actuation system to enlarge boreholes and save rig time, the firm said in a press release on Thursday.

Based on hydraulically expandable reamer technology, the new reamer actuation system, called Rhino XC, is designed for improved drilling and hole enlargement operations. Its design increases torque and load-carrying capacity while reducing drilling-generated vibrations which produce undergauge and irregular boreholes.

Rhino XC provides complete control of reamer cutter-block deployment, regardless of well-inclination angle, the firm said. Its flow activation system eliminates the need for time-consuming pumpdown device activation, allowing the reamer to be placed below inner diameter-restricted bottomhole assembly components, which reduces the pilot-hole interval at total depth. 

“With its on-demand capabilities and unlimited activations and deactivations of the cutter blocks, customers can optimise their underreaming program in real time,” said Schlumberger’s Dean Watson, president of Drilling Tools & Remedial. “In deepwater environments, this provides huge savings for our customers by enabling faster and reliable activation.”

Rhino XC has been run offshore Norway by an undisclosed Schlumberger client, the firm said, where a 9,283 ft run was completed in a personal record of 300 circulating hours by adjusting the pump flow rate.
