摘要： An apparatus for monitoring rod rotation in a rod lift system. The apparatus comprises one or more sensors that reside on the rod string of the rod lift system. The sensor is configured via a processor to generate a signal indicative of radial position of the sensor relative to an external frame of reference. The signal may be sent to a wireless I/O module, with the signals being indicative of at least partial rotation or, alternatively, a lack of rotation, of the rod-string. The processor is configured to generate an alarm if an absence of rod rotation is detected while the rod lift system is running and transmit this signal to the nearby wireless I/O module. A method for monitoring a reciprocating rod lift system is also provided.

摘要： Methods of geophysical prospecting are described herein. In the described methods, a data set of electromagnetic readings from a marine geophysical survey is obtained and loaded into a computer processing system. Using the computer processing system, a high-frequency subset of the data is selected based on a frequency threshold, and a seawater resistivity map is resolved from the subset for a seawater portion of the survey by inversion. The seawater resistivity map can subsequently be used to resolve a resistivity map of the seabed from the data set by inversion.

摘要： A method and a resistivity image logging tool connected or connectable to one or more processing devices process geological log data to construct missing information from destroyed or occluded parts using cues from observed data. The geological log data signals can be generated through use of the logging tool having one or more electrodes interacting with a formation intersected by a borehole. The processing involves the steps of: in respect of one or more data dimensions associated with missing values in a log data set, decomposing the signal into a plurality of morphological components; and morphologically reconstructing the signal such that missing values are estimated.
