Patent number: 10465498Abstract: The disclosed embodiments include a system and method in which a plurality of shock sensing subassemblies are arranged within the tool string to monitor the transient response of formation characteristics to various stimuli, including changes in pressure and temperature of a region of a wellbore that is nearby the formation. The systems and methods involve gathering measurements that reflect the transient response and comparing the measured data to predicted data. The results of the comparison can be used to determine formation properties and to refine and improve modeling processes used to generate the predicted data.Type: GrantFiled: December 31, 2013Date of Patent: November 5, 2019Assignee: Halliburton Energy Services, Inc.Inventors: John P.

Patent number: 10337299Abstract: A perforating apparatus for a gun string is presented. The apparatus experiences an axial load and potentially a radial load during use. A central charge-carrier supports shaped-charges and substantially bears the axial load on the apparatus during use. The charge-carrier is positioned within an exterior sleeve and the plurality of shaped-charges, upon detonation, perforate the exterior sleeve. The exterior sleeve does not bear a substantial portion of the axial load on the apparatus and can therefore be thinner and cheaper than in prior art assemblies. An annular space can be defined between the charge-carrier and exterior sleeve. The exterior tubular can bear the radial load due to differential pressure in one embodiment. Alternately, the apparatus includes radial support members extending between the charge-carrier and sleeve for transmitting radial load to the charge-carrier. Alternately, the sleeve and charge-carrier abut one another along a substantial portion of the length of the charge-carrier.Type: GrantFiled: March 2, 2012Date of Patent: July 2, 2019Assignee: Halliburton Energy Services, Inc.Inventors: John H Hales, Samuel Martinez, John P. Rodgers
