STAVANGER, Norway –Schlumberger has released its next-generation Rhino XC on-demand reamer. The tool provides unlimited activation of the flow actuation to reliably enlarge boreholes, says the company.
The XC builds on the Rhino XS technology to control reamer cutter-block deployment regardless of well inclination and the flow activation system eliminates the need for pumpdown actuation.
In an application offshore Norway, a 9½-in x 10¼-in section with the potential for several hole-related issues was reamed. For flexibility in handling borehole instability, the operator required on-demand capability to close reamer flow to the annulus.
The Rhino XC was run, allowing cycling of the reamer multiple times during the course of the run by changing the pump flow rate in a predetermined sequence. The resulting 9,283-ft (2,829-m) run was completed in just over 300 circulating hours to set a new run-length record for the client.
