Publication number: 20120298423Abstract: Various embodiments of an expandable downhole tool for use in drilling of a wellbore are disclosed. The expandable tools disclosed herein may be used as an underreamer to enlarge a borehole, or may be used to stabilize a drilling system in a previously underreamed borehole or in a borehole that is being underreamed while drilling progresses. The various embodiments of the expandable tools disclosed herein have a higher hydraulic capacity than prior art underreamers. An increase in hydraulic energy delivered to the cutting structures may advantageously improve the rate of removal of cuttings from the cutting structures (improved cuttings evacuation), may decrease cutter element wear, and may prevent damage or premature failure. Improved cuttings evacuation may also provide for improved cutting action and increased penetration rates.Type: ApplicationFiled: May 26, 2011Publication date: November 29, 2012Applicant: SMITH INTERNATIONAL, INC.Inventors: Brian Cruickshank, Manoj Mahajan, Navish Makkar, Sameer Bhoite, Charles Dewey
