Patent number: 10267947Abstract: A neutron detection apparatus, method, and system includes a scintillation device that emits photons in response to received neutron energy incident on the device. A gamma radiation source, coupled to the scintillation device and configured to emit a reference energy, is also detected by the scintillation device. The reference energy has a different energy than the neutron radiation. A light sensor is coupled to the scintillation device. The light sensor receives and converts the emitted photons into an electrical signal comprising an indication of both the reference energy and the received neutron energy.Type: GrantFiled: September 29, 2014Date of Patent: April 23, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Weijun Guo, Da Lou, Ronald E.

Patent number: 6525534Abstract: A system and methods for improving the vertical resolution of NMR logs based on data acquisition methods and signal processing techniques that need not apply Phase Alternated Pair Stacking (PAPS). The method is based on reducing the level of coherent non-formation signals, by estimating these signals and removing the estimates from the underlying NMR pulse echo trains. Once the estimated non-formation signal components have been removed, standard NMR processing methods are applied to derive petrophysical properties of the formation being investigated. In a preferred embodiment the NOPAPS method of this invention is practiced along with a data acquisition sequence, which can be used to further increase the logging speed of the tool or vertical resolution of the measurements.Type: GrantFiled: June 15, 2001Date of Patent: February 25, 2003Assignee: Halliburton Energy Services, Inc.Inventors: Ridvan Akkurt, Ronald E.

Patent number: 5392858Abstract: A well penetrator consists of a number of hydraulic fluid control components and a carriage carrying a hydraulic motor and a mill bit supported in a housing which is moveable down a well casing. The control components cause the carriage carrying the mill bit to be indexed up a predetermined distance relative to the well casing and then extended gradually into contact with the well casing while being rotated by the hydraulic motor. After the mill bit completes a hole through the well casing, the hydraulic components index the mill bit back down to its starting position and align a nozzle on the outer end of a high pressure lance with the opening in the casing to direct fluid from the nozzle as the lance is moved outwardly through the hole in the casing drilled by the mill bit.Type: GrantFiled: April 15, 1994Date of Patent: February 28, 1995Assignee: Penetrators, Inc.Inventors: Alan D. Peters, Randolph A. Busch, Robert W. McQueen, Thomas A. Huddle, Ronald E. Cherry
