Patent number: 9110166Abstract: In various embodiments, apparatus and methods are provided to perform acoustic imaging. An acoustic wave can be acquired at a detector, where the acoustic wave propagates from a target to the detector. The target may be acoustically illuminated to provide the acoustic wave. A signal from the detector in response to acquiring the acoustic wave can be processed in a model such that the processing implements a synthetic acoustic lens to generate an image of the target. Additional apparatus, systems, and methods are disclosed.Type: GrantFiled: December 1, 2011Date of Patent: August 18, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Chung Chang, Arthur Cheng, Chen Li, Steve Zannoni

Patent number: 8885163Abstract: Various systems and methods for performing optical analysis downhole with an interferogram (a light beam having frequency components with a time variation that identifies those frequency components. The interferogram is produced by introducing an interferometer into the light path, with the two arms of the interferometer having a propagation time difference that varies as a function of time. Before or after the interferometer, the light encounters a material to be analyzed, such as a fluid sample from the formation, a borehole fluid sample, a core sample, or a portion of the borehole wall. The spectral characteristics of the material are imprinted on the light beam and can be readily analyzed by processing electronics that perform a Fourier Transform to obtain the spectrum or that enable a comparison with one or more templates. An interferometer designed to perform well in the hostile environments downhole is expected to enable laboratory-quality measurements.Type: GrantFiled: December 23, 2009Date of Patent: November 11, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Marian L. Morys, Steve Zannoni, Christopher M. Jones

Patent number: 8866632Abstract: A method of communication from the surface with to the downhole logging tool string is disclosed. The method includes movement of the drill pipe string up or down at the surface to create coded signature signals by the downhole logging tool string and send those signature signals to a processor in the downhole logging tool string that has been preprogramed to recognize the signature signals.Type: GrantFiled: June 28, 2012Date of Patent: October 21, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Andrew Albert Hrametz, Nathan James Harder, Steve A. Zannoni

Patent number: 8510050Abstract: Downhole fluid typing with pulsed neutron logging. A method comprises obtaining at least one capture gamma count rate at a particular borehole depth, calculating a fluid type indicative response value for the borehole depth, and determining at least one fluid type based on the response value. A system comprises a downhole tool, including a neutron source, at least one gamma detector, and a processor coupled to a memory. The memory stores a program that, when executed by the processor, causes the processor to obtain at least one capture gamma count rate for a particular borehole depth. The processor calculates a fluid type indicative response value for the borehole depth and determines at least one fluid type based on the response value.Type: GrantFiled: September 28, 2009Date of Patent: August 13, 2013Assignee: Halliburton Energy Services, Inc.Inventors: Jerome Truax, Steve Zannoni, Daniel Dorffer, Weijun Guo

Publication number: 20110202276Abstract: Downhole fluid typing with pulsed neutron logging. A method comprises obtaining gamma count rates at a particular borehole depth; calculating a fluid type indicative response value for the borehole depth; determining at least one fluid type based on the response value for the particular borehole depth; and producing a display of the at least one fluid type corresponding to the borehole depth. A system comprises a downhole tool comprising a neutron source and at least one gamma detector; gamma count rates produced due to gamma arrivals at the gamma detector(s); and a processor coupled to a memory, wherein the memory stores a program that, when executed by the processor, causes the processor to: calculate a fluid type indicative response value for a particular borehole depth based on the gamma count rates; and determine at least one fluid type based on the response value for the particular borehole depth.Type: ApplicationFiled: September 28, 2009Publication date: August 18, 2011Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventors: Jerome Truax, Steve Zannoni, Daniel Dorffer, Weijun Guo
