Patent number: 10067262Abstract: Sonic data, ultrasonic data, density data, cased-hole neutron data, and open-hole neutron data of the wellbore are obtained. The sonic and ultrasonic data provides the amplitude, frequency, and phase of the altered sonic and ultrasonic waves. The far counts, near counts, and energy spectrum are obtained from density data, cased-hole (CH) neutron data, and open-hole (OH) neutron data. The amplitude, frequency, and phase provide the interface densities of the first, second, and third interfaces. The hydrogen index (HI) of the formation and the cased wellbore are obtained from the CH and OH neutron data. The widths of the second and third interfaces are obtained from the HI's and the densities of the second and third interfaces.Type: GrantFiled: September 4, 2015Date of Patent: September 4, 2018Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Luis F. Quintero, Ivo Foianini, Javier Fadul

Patent number: 9945974Abstract: Sonic data, ultrasonic data, and density data of the annulus are obtained using a sonic tool, an ultrasonic tool, and a density tool, respectively, included in a tool string. A first deconvolution operation is performed to obtain an amplitude, a frequency, and a phase of the modified sonic wave. A first inverse modeling operation results in a first density value of the annular media. A second deconvolution operation is performed to obtain an amplitude, a frequency, and a phase of the modified ultrasonic wave. A second inverse modeling operation results in a second density value of the annular media. A third deconvolution operation is performed to obtain far counts, near counts, and an energy spectrum of gamma rays. A third inverse modeling operation results in a third density value of the annular media.Type: GrantFiled: September 4, 2015Date of Patent: April 17, 2018Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Luis F.

Patent number: 9284824Abstract: Methods and apparatus are presented for a “disappearing” perforator gun assembly. In a preferred method of perforating a well casing, inserted into the well casing is a tubing conveyed perforator having an outer tubular made from a metallic glass alloy having high strength and low impact resistance. An inner structure is positioned within the outer tubular and holds one or more explosive charges. Upon detonating the explosive charges, the outer tubular is fragmented. The inner structure is preferably also substantially destroyed upon detonation of the one or more explosive charges. For example, the inner structure can be made from a combustible material, corrodible, dissolvable, etc., material. A disintegration-enhancing material is optionally positioned between the outer tubular and the inner structure. Additional embodiments are presented having gun housings which dematerialize upon detonation of the charges.Type: GrantFiled: October 7, 2013Date of Patent: March 15, 2016Assignee: Halliburton Energy Services, Inc.Inventors: Javier Fadul, Paul Herman, Paul Ringgenberg, Randy Moore, Michael Fripp, Dennis Crowdis, John Hales, Bryan Powell
