Filed:

Sep 30, 2009

Appl. No.:

12/570852

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 10/18

US Classification:

175340, 175393

Abstract:

Earth-boring drill bits include a bit body including a blockage-resistant internal fluid passageway. The blockage-resistant internal fluid passageway includes at least one internal fluid passageway formed in the bit body and a cuttings filtering feature formed in the at least one internal fluid passageway configured to prevent at least some cuttings from flowing through the at least one internal fluid passageway. In one embodiment, the cuttings filtering feature includes at least one lateral member extending transversely across the at least one internal fluid passageway. In another embodiment, the cuttings filtering feature includes forming a central portion of the at least one internal fluid passageway with a width along a lateral axis thereof less than an average width of a fluid path extending through a nozzle disposed at least partially within the at least one internal fluid passageway. Methods of forming the blockage-resistant internal fluid passageway are also disclosed.

E21B 10/62
E21B 7/00

US Classification:

175 57, 175385

Abstract:

An apparatus for engaging a subterranean borehole includes a bi-center bit having backup cutting elements thereon. The bi-center bit includes a pilot bit section and a reamer bit section adjacent to the pilot bit section. The pilot bit section includes at least one primary cutting element and at least one backup cutting element rotationally trailing and laterally offset from the at least one primary cutting element. Methods of drilling a subterranean borehole include engaging a first portion of a borehole with a reamer bit section of a drill bit and simultaneously engaging a second, opposing portion of the borehole with a pilot bit section adjacent to the reamer bit section.

Abstract:

A system for the automatic and continuous determination of the efficiency of a fossil fuel-fired vapor generator for utilization by an automatic load control (88) to control the distribution of the system load among a plurality of generators, wherein various heat losses from various combustion sources are separately determined, the individual losses summed (80) and subtracted (86) from 100 percent to obtain a measure of the vapor generator efficiency.
