摘要： A sensor device includes a tubular body having a first end and a second end opposite the first end, a pressure plug on the first end of the tubular body, and a sensor tip on the second end of the tubular body, wherein the sensor tip comprises an open end opposite the tubular body and an optical tip removably positioned through the open end and held in place by a removable cap. The optical tip includes an optical rod and a rod holder. The sensor device further includes an optical fiber extending from the pressure plug, through the tubular body, and into the sensor tip where the optical fiber is optically coupled to the optical rod. The pressure plug may include a slack cavity where the optical fiber is in slack under neutral temperature and pressure conditions to withstand expansion of the sensor device under high temperature or pressure conditions.

摘要： Methods and systems are provided for inverted detection and positioning of a strip-like subterranean tunnel in a mountain mass, pertaining to the field combining theories of the discipline of geophysics and remote sensing technology. The method includes: using a model of thermal radiation between a mountain mass and an air layer in conjunction with DEM data to calculate solar radiation energy, and iteratively filtering out background heat flow field energy of the mountain mass; calculating mountain mass background heat propagation energy with reference to hyperspectral data; using a subterranean target inversion model to filter out each layer of background heat flow field energy of the mountain mass in an infrared remote sensing image, and acquiring an optimal elevation of the strip-like subterranean tunnel in the mountain mass and a disturbance signal distribution image constructed via strip-like subterranean tunnel heat flow field energy in each layer of the mountain mass; and using a Hough transform detection method to detect a straight line in the disturbance signal distribution image, performing fitting according to the principle of relevance of tunnel engineering design to acquire a detected location of the tunnel. In this way, inverted detection and positioning of a strip-like subterranean tunnel in a mountain environment is achieved.

摘要： A system and method for making measurements inside a wellbore makes use of a diamond crystal with a nitrogen vacancy center (NV-center) to sense temperature, pressure, magnetic fields, strain, electric fields, or other parameters of the downhole environment. The system includes a microwave source that can be positioned to produce microwaves inside the wellbore and a light source that can be positioned to produce interrogation light inside the wellbore. The NV-center of the diamond is struck by the interrogation light. A spectrometer can be adapted to receive the excitation light output from the NV-center and produce a spectrum of the excitation light. The spectrum is indicative of the value of the parameter inside the wellbore.

摘要： Respective embodiments disclosed herein include methods and apparatuses (1) for surveying a mine bench or other material body using at least seismic data obtained via geophone and measurement module data synchronized via a wireless link; (2) for generating hyperspectral panoramic imaging data of a blast hole or other borehole; or (3) for allowing a neural network to facilitate a differential blast design that targets a first bench part more weakly than the differential blast design targets a second bench part (along the same mine bench) at least partly based on data indicative of a much higher concentration of a valuable material in the second bench part than in the first.

摘要： The present disclosure describes methods and systems for determining source rock potential in a subterranean region of a hydrocarbon reservoir. One method includes: receiving, a terahertz (THz) scanning image from an in-situ THz scanner that is attached to a wellbore at a first subterranean location, wherein the wellbore extends into the subterranean region of the hydrocarbon reservoir; identifying, components of a source rock in the first subterranean location based on the THz scanning image; and determining, the source rock potential at the first subterranean location based on the identified components of the source rock.

摘要： Two or more Integrated Computational Element (“ICE”) structures are designed and utilized in an optical computing device to combinatorily reconstruct spectral patterns of a sample. To design the ICE structures, principal component analysis (“PCA”) loading vectors are derived from training spectra. Thereafter, two or more ICE structures having spectral patterns that match the PCA loading vectors are selected. The selected ICE structures may then be fabricated and integrated into an optical computing device. During operation, the ICE structures are used to reconstruct high resolution spectral data of the samples which is utilized to determine a variety of sample characteristics.

摘要： A method for performing a formation-related physical action includes: receiving image data of a wall of a borehole penetrating a formation, the image data having image data of fractures intersecting the wall of the borehole; and defining a volume surrounding the borehole. The method also includes determining a surface area of each fracture intersecting the volume at each defined depth in a plurality of depths and calculating a fracture density for each defined depth based on the surface area of each fracture intersecting the volume at each defined depth in a plurality of depths and a size of the volume. The method further includes performing the formation-related physical action based on the fracture density for each defined depth using apparatus configured to perform the formation-related physical action.

摘要： Fouling of or damage to an electromagnetic radiation-transparent window can preclude one from obtaining satisfactory images with an image acquisition unit, such as a camera. Certain types of environments may be particularly prone toward promoting fouling or damage, and manual cleaning or repair of an electromagnetic radiation-transparent window may be difficult in some circumstances. These issues may be particularly prevalent when imaging drill cuttings and other solids obtained from a wellbore due to the complex sampling environment in which these solids are often disposed. Wellhead imaging systems can comprise: a flow pathway extending from a wellbore; an electromagnetic radiation-transparent window external to the wellbore establishing optical communication with the flow pathway; an image acquisition unit in optical communication with the flow pathway via the electromagnetic radiation-transparent window; and a movable barrier that is also electromagnetic radiation-transparent and is disposed between the electromagnetic radiation-transparent window and the flow pathway.
