Publication number: 20100126768Abstract: A sealing assembly having a flexible sleeve and a means for sealing a top portion of the sleeve around a plurality of cables, such as by a hook and loop type fastener attached at the top portion of the sleeve. The sleeve is configured to receive at least one cable therethrough and a bottom portion of the sleeve is configured to be secured to a surface. The sleeve can also be electrically conductive such that the sleeve dissipates static electricity from the cable to the surface. The sealing assembly can also have a grommet positioned adjacent the bottom portion of the sleeve. The grommet has a first wall having a plurality of apertures for connecting the grommet to a surface and a second wall that extends substantially perpendicular to the first wall and is configured to extend through an aperture in the surface. The second wall is flexible to protect the cable from sharp edges associated with the aperture in the surface.Type: ApplicationFiled: February 8, 2010Publication date: May 27, 2010Applicant: Panduit Corp.Inventors: Joseph Allen Dukes, Kevin Larry Nelson, Rhonda Johnson

Publication number: 20100126770Abstract: A steering tool configured for making azimuthal and non-azimuthal formation evaluation measurements is disclosed. In one embodiment a rotary steerable tool includes at least one formation evaluation sensor deployed in the steering tool housing. The steering tool may include, for example, first and second circumferentially opposed formation evaluation sensors or first, second, and third formation evaluation sensors, each of which is radially offset and circumferentially aligned with a corresponding one of the steering tool blades. The invention further includes methods for geosteering in which a rotation rate of the steering tool housing in the borehole (and therefore the rotation rate of the formation evaluation sensors) is controlled. Steering decisions may be made utilizing the formation evaluation measurements and/or derived borehole images.Type: ApplicationFiled: November 24, 2008Publication date: May 27, 2010Applicant: PATHFINDER ENERGY SERVICES, INC.Inventor: Junichi Sugiura

Publication number: 20100126771Abstract: Drill bits are provided. The drill bits are of the fixed-cutter, rotary-type. The drill bits have a plurality of blades having cutting elements disposed therealong. Junk slots are formed between the respective blades. A knife opening is formed in at least two of the junk slots. Preferably, the knife openings are disposed substantially transverse to a longitudinal axis of the drill bit. The drill bit also has one or more ribbon cutters. The ribbon cutters cyclically protrude through knife openings in the junk slots in order to facilitate the fragmentation of cuttings ribbons moving through the junk slots during a drilling operation.Type: ApplicationFiled: April 21, 2008Publication date: May 27, 2010Inventors: Pavlin B. Entchev, John H. Jackson, John K. Montgomery
