20140034821 | WELL-LOGGING APPARATUS INCLUDING AZIMUTHALLY-SPACED, NOBLE GAS-BASED DETECTORS - A well-logging device may include a housing to be positioned within a borehole of a subterranean formation, and at least one radiation source carried by the housing to direct radiation into the subterranean formation. The well-logging device may also include noble gas-based radiation detectors carried by the housing in azimuthally spaced relation to detect radiation from the subterranean formation. A controller may determine at least one property of the subterranean formation based upon the detected radiation from the noble gas-based radiation detectors. | 02-06-2014 |
20140034822 | WELL-LOGGING APPARATUS INCLUDING AXIALLY-SPACED, NOBLE GAS-BASED DETECTORS - A well-logging device may include a housing to be positioned within a borehole of a subterranean formation and at least one radiation source carried by the housing to direct radiation into the subterranean formation. The well-logging device may also include noble gas-based radiation detectors carried by the housing to detect radiation from the subterranean formation. At least one of the noble detectors is at a first axial spacing from the at least one radiation source, and at least one other of the noble gas-based radiation detectors is at a second axial spacing from the at least one radiation source different from the first axial spacing. A controller may determine at least one property of the subterranean formation based upon the detected radiation from the noble gas-based radiation detectors. | 02-06-2014 |
20140097336 | Apparatus and Methods for Measuring Formation Characteristics - An apparatus can measure characteristics of a formation surrounding a borehole. The apparatus includes a tool body having a neutron measurement section and a density measurement section. The neutron measurement section includes a neutron source and a neutron detector arrangement spaced in an axial direction from the neutron source. The density measurement section includes a gamma ray source and a gamma ray detector arrangement spaced in an axial direction from the gamma ray source. The neutron measurement section and the density measurement section are positioned in the tool body so that the sections overlap in the axial direction and are azimuthally spaced apart in the tool body. The tool body also includes shielding to block a direct signal path from the neutron source to the gamma ray detector arrangement and to block a direct signal path from the gamma ray source to the neutron detector arrangement. | 04-10-2014 |
20150293256 | METHOD AND SYSTEM OF DETERMINING CHARACTERISTICS OF A FORMATION - Determining characteristics of a formation. At least some of the illustrative embodiments are methods including determining at least one characteristics of a shale formation. The determining may include: collecting optically interacted electromagnetic radiation from a portion of the shale formation; directing a first portion of the optically interacted electromagnetic radiation from the formation to a first multivariate optical element (MOE), the first MOE creates first modified electromagnetic radiation; applying the first modified electromagnetic radiation to a first detector, the first detector creates a first signal; and determining a first characteristic of the shale formation from the first signal. | 10-15-2015 |

20160187527 | COLLOCATED RADIATION SENSING - Collocated radiation sensing is provided. In one possible implementation, a tool to be placed in a wellbore includes a first source of nuclear radiation and a second source of nuclear radiation. The tool also includes one or more sensors configured to discriminate between radiation emitted by the first and second sources and correctly attribute the radiation to the source from which the radiation was emitted. The one or more sensors are collocated to be within a range of radiation scattered from the first source and the second source by an environment of the formation. | 06-30-2016 |
