Patent number: 9709692Abstract: A logging tool for performing resistivity measurements on the sidewall of a borehole in an earth formation is provided with a circumferential series of evenly-spaced measurement electrodes providing complete circumferential coverage of resistivity measurements. In one embodiment, the measurement electrodes are carried on a conductive pad circumferentially surrounding an elongate mandrel or tubular. The conductive pad is held at a voltage adapted to focus measurement current into the sidewall of the borehole. Preferably, the pad has dimensions relative to the measurement electrodes and a standoff distance between the measurement electrodes and said borehole wall to effectively focus the measurement current into the borehole wall. In accordance with one aspect of the invention, the measurement electrodes are spaced apart by a distance that is less than the width of each measurement electrode, thereby ensuring full circumferential resolution.Type: GrantFiled: October 17, 2008Date of Patent: July 18, 2017Assignee: BAKER HUGHES INCORPORATEDInventors: Gregory B. Itskovich, Alexandre N. Bespalov, Farhat A. Shaikh, Peter John Nolan

Publication number: 20110198093Abstract: A downhole tool having a body, a transducer within the body, and an opening formed through a sidewall of the body. The opening provides a port through which the transducer can communicate from within the body. An elastomeric boot in the body covers the opening and is a barrier that prevents fluid ingress into the downhole tool. An expandable sleeve envelopes the elastomeric boot and provides support that limits bulging of the elastomeric boot from within the body through adjacent openings in the body. An example sleeve is made from elongated members woven into a tubular.Type: ApplicationFiled: January 28, 2011Publication date: August 18, 2011Applicant: BAKER HUGHES INCORPORATEDInventor: Farhat A.

Patent number: 7226303Abstract: An electrical connector for use in downhole environment and methods for use are provided. In one aspect, an electrical connector comprises a substantially cylindrical connector body having a first end and a second end. A groove is formed around an outer surface of the connector body wherein the groove has a first substantially conically beveled surface on a side of the groove proximate the second end. A back-up ring has a second substantially conically beveled surface and is adapted to act cooperatively with an elastomer seal to close an extrusion gap between the connector body and a surrounding surface when the elastomer seal is exposed to a positive differential pressure from the first end to the second end. In another aspect, a conical surface on the connector body is forced to engage a mating surface on a bulkhead, thereby forming a metal to metal seal.Type: GrantFiled: February 22, 2005Date of Patent: June 5, 2007Assignee: Baker Hughes IncorporatedInventor: Farhat Shaikh

Patent number: 4628495Abstract: A measuring and transmitting apparatus for use in a drill string of a well drilling rig has an elongated tubular member functioning as a drill collar in a drill string. This apparatus includes an instrument having transducers that measure lithological and geophysical parameters in the borehole and derive from them data that is encoded into pressure pulsations of the mud flow of the drill string by a modulated signal generator. The modulated signal generator has a valve assembly that selectively restricts the mud flow to introduce the data. The valve is constructed with a movable valve element that is displaced into an orifice located in the mud flow stream. The movable valve element is mounted in a pressure balanced and an area balanced configuration in order that it can be displaced between extended and retracted positions by a valve actuator without regard to the mud pressure either within the drill string or in the borehole annulus around the drill string.Type: GrantFiled: August 9, 1982Date of Patent: December 9, 1986Assignee: Dresser Industries, Inc.Inventors: James M.
