Assignee:
Baker Hughes Incorporated
International Classification:
E21B010/00
US Classification:
175/337000
Abstract:
An improved drill bit for use in drilling operations in a wellbore comprising a bit body including a plurality of bit legs, each supporting a rolling cone cutter, a coupling member formed at an upper shank portion of said bit body, at least one sensor for monitoring at least one condition of said improved drill bit during drilling operations, and an electronics bay portion defined in-part by said upper shank portion of said bit body for housing at least one monitoring circuit.
Drilling Apparatus With Reduced Exposure Of Cutters
US Patent:
2006027, Dec 14, 2006
Filed:
Aug 21, 2006
Appl. No.:
11/507279
Inventors:
Mark Dykstra - Kingwood TX, US

International Classification:
E21B 10/62
US Classification:
175057000, 175408000, 175425000
Abstract:
A rotary drilling apparatus and method for drilling subterranean formations, including a body being provided with at least one cutter thereon exhibiting reduced, or limited, exposure to the formation, so as to control the depth-of-cut of the at least one cutter, so as to control the volume of formation material cut per rotation of the drilling apparatus, as well as to control the amount of torque experienced by the drilling apparatus and an optionally associated bottomhole assembly regardless of the effective weight-on-bit are all disclosed. The exterior of the drilling apparatus may include a plurality of blade structures carrying at least one such cutter thereon and including a sufficient amount of bearing surface area to contact the formation so as to generally distribute an additional weight applied to the drilling apparatus against the bottom of the borehole without exceeding the compressive strength of the formation rock.
