Patent number: 10539001Abstract: A method for drilling a borehole penetrating the earth includes: inputting drilling parameters as a function of depth used to drill one or more offset boreholes and rate of penetration using the drilling parameters, any drilling dysfunctions that occurred using the drilling parameters, and one or more lithologies as a function of depth for the one or more offset boreholes. The method also includes identifying those drilling parameters that correspond to a rate of penetration (ROP) that meets or exceeds an ROP threshold for each input lithology and a minimum number of drilling dysfunctions or minimum magnitude of a drilling dysfunction to provide identified drilling parameters; correlating a borehole plan comprising a borehole path and one or more assumed lithologies as a function of depth to the one or more lithologies of the one or more offset boreholes; and drilling the borehole with the drill rig using the identified drilling.Type: GrantFiled: November 22, 2017Date of Patent: January 21, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Franck T.

Publication number: 20120051552Abstract: A system and method for modulating the sound pressure that is output from an audio transducer is disclosed. In one embodiment, the method includes receiving an audio signal and placing the audio signal across a voice coil of the transducer. In addition, a voltage is applied across a field coil of the transducer, the field coil being separate from the voice coil. And the voltage that is applied across the field coil is adjusted so as to modulate the sound pressure output from the audio transducer.Type: ApplicationFiled: November 4, 2011Publication date: March 1, 2012Applicant: FLUXTONE, INC.Inventor: Stephen Carey
