20220214468 | RETRIEVABLE FIBER OPTIC VERTICAL SEISMIC PROFILING DATA ACQUISITION SYSTEM WITH INTEGRATED LOGGING TOOL FOR GEOPHONE-EQUIVALENT DEPTH ACCURACY - A wellbore system includes a logging unit having a retrievable logging cable coupled to a downhole tool within a wellbore and a depth correlation unit in the downhole tool that provides current depth data for the wellbore through the retrievable logging cable for recording of a current depth by the logging unit. The wellbore system also includes a distributed acoustic sensing unit that includes a seismic processing unit and a seismic profiling unit connected to a separate optical cable of the retrievable logging cable having distributed acoustic sensing channels, wherein an assignment of the distributed acoustic sensing channels along the separate optical cable is determined by an offset distance between the current depth of a formation reference region within the wellbore and a previous reference depth of the formation reference region within the wellbore. A distributed acoustic sensing method is also included. | 2022-07-07 |
20220214469 | Pro Scanner Magnetic Stud Finder - Certain exemplary embodiments can provide a device comprising an upper housing, a lower housing, an electronics module, an electronics button, a side button, and a strip magnet. The strip magnet is coupled to the lower housing. The strip magnet is constructed to cause resistance to motion across a metal fastener. The resistance to motion is perceptible to a user of the device. The resistance is indicative of a location of the metal fastener and, thereby, allows the user of the device to locate the metal fastener if the electronics module fails to detect the metal fastener. | 2022-07-07 |
