Abstract: systems and methods are provided for imaging drill cuttings, which employ a uv source including a uv led, which is configured to illuminate a sample volume with uv radiation that interacts with oil-bearing cuttings to cause fluorescence emission. a camera system is configured to capture at least one image of the cuttings based on fluorescence emission. in another aspect, methods are provided for characterizing oil content in drill cuttings that involve capturing at least one we image of the cuttings illuminated by white light, capturing at least one uv image of the cuttings based on fluorescence emission from uv radiation, processing the at least one we image to determine a first pixel count for all cuttings, processing the at least one uv image to determine a second pixel count for oil-bearing cuttings, and determining a parameter representing oil content of the cuttings based on the first and second pixel counts.

Abstract: systems and methods are described for calculating an emission rate of a fugitive gas based on a gas density image of the fugitive gas. in an example, a computing device receives a gas density image of a fugitive gas from a camera. the computing device determines how to optimize the fugitive gas in the camera's field of view and instructions the camera to adjust its bearing and zoom accordingly. the camera captures one or more additional images of the fugitive gas, and the computing device stitches the images together where appropriate. the computing device then calculates the emission rate by delineating the fugitive gas in the image and determining a flux of the gas using one of various calculation methods.

Abstract: a method includes assembling a model including a plurality of independent objects. the independent objects include surfaces, properties, and zones. the method also includes decomposing the model into vertical columns, tiles, or both. the method also includes discretizing an incoming request into the vertical columns, the tiles, or both. in response to the discretized request, the method also includes performing a vertical pin analysis on the model to retrieve a portion of the surfaces, a portion of the properties, or both that are geo-located in the vertical columns, the tiles, or both. the method also includes modelling the retrieved portions to generate an output. the method also includes comparing the output with subsurface data. the method also includes modifying the model based at least partially upon the comparison.

Abstract: a downhole motor includes a primary fluid path between a housing and a rotor and a secondary fluid path between the rotor and a stator. fluid is diverted from the primary fluid path through a secondary inlet to the secondary fluid path to lubricate the motor. a magnet is located proximate the secondary inlet to bias magnetic particles in the drilling fluid away from the secondary inlet.
