The Rhino XC on-demand reamer, released at ONS by Schlumberger, is a next-generation reaming tool that provides unlimited activation of the flow actuation system to reliably enlarge boreholes.
Building on Rhino XS hydraulically expandable reamer technology, the Rhino XC is designed to provide complete control of reamer cutter-block deployment, regardless of well-inclination angle. 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 resulting in a reduced pilot-hole interval at total depth.
‘With its on-demand capabilities and unlimited activations and deactivations of the cutter blocks, customers can optimize their underreaming program in real time,’ noted Dean Watson, president, Schlumberger Drilling Tools & Remedial. ‘In deepwater environments, this provides huge savings for our customers by enabling faster and reliable activation.’
Offshore Norway, one North Sea customer undertook a long and challenging 91/2in x 101/4in large-diameter (1/2in) LP actuator ports: one for easy alignment to supply lines, minimising debris buildup, and one with an optional safety head designed to protect the actuator from overpressurization.
