Publication number: 20180266179Abstract: Disclosed is a hammer reamer comprising cutting wheels, a product-pulling feature, and a hammer component operable to deliver a percussive cycle of an internal piston component. Notably, an internal impact surface within the head of the hammer reamer is positioned relative to the piston component in the hammer consistent with a “sweet spot” position of a drill bit used in a pilot boring configuration. Unlike a slidably engaged drill bit, however, the internal impact surface in the hammer reamer is fixed in place so that the impact surface remains in the “sweet spot” of the piston stroke range. In this way, even though the hammer reamer is being pulled back through a bore while the drill string is being retracted, the hammer component may continue to deliver percussive blows to the hammer reamer head to introduce a vibratory force that contributes to the efficiency of the reaming process.Type: ApplicationFiled: May 8, 2018Publication date: September 20, 2018Inventors: Cary Cooper, Travis Parr

Publication number: 20180266212Abstract: A bottom hole assembly for performing a borehole treatment has a plurality of ported valve housings where the housings have an assembly of shifting sleeves. The first sleeve is shifted uphole to open the port in the housing and lock the first sleeve in the ports open position. A second sleeve in the same housing is shifted in the same direction as the first sleeve to close the ports in the housing. The second sleeve has profiles for shifting it up to close the housing ports and back down to reopen the housing ports after closing them.Type: ApplicationFiled: March 16, 2017Publication date: September 20, 2018Applicant: BAKER HUGHES INCORPORATEDInventors: Jeffrey B.

Publication number: 20180266215Abstract: A wellbore assembly includes a conveyance member including at least one of a continuous spooled rod, a wireline, and a slickline; an accumulator system connected to the conveyance member; and a setting tool connected to the accumulator system. The accumulator system may be configured to supply a fluid pressure to actuate the setting tool. A method of operating a wellbore tool includes lowering a wellbore assembly into a wellbore using a conveyance member including at least one of a continuous spooled rod, a wireline, and a slickline, wherein the wellbore assembly includes an accumulator system and a setting tool. The method includes actuating the accumulator system to provide a fluid pressure to the setting tool. The method also includes actuating the setting tool using the fluid pressure.Type: ApplicationFiled: May 18, 2018Publication date: September 20, 2018Inventors: Walter Stone Thomas FAGLEY, IV, Gary Duron INGRAM, Paul James WILSON, Simon J.

Publication number: 20180266216Abstract: A downhole generator system including a controlled rectifier for receiving electrical power from a generator and outputting rectified electrical power. A control system controls the operation of the controlled rectifier and a chopper circuit connected to the output of the controlled rectifier connects a load selectively across the output of the controlled rectifier to regulate the output of the generator system. The control system controls the chopper circuit and/or the controlled rectifier based at least in part on a feed-back signal representative of an electric current output by the generator system and an electric current passing through the chopper circuit.Type: ApplicationFiled: September 21, 2016Publication date: September 20, 2018Inventors: Mustafa Kamil GUVEN, Torgeir RUSTEN, In Chul JANG
