Methods, apparatus, systems, and computer-readable media are set forth for providing a graphing database for exploration and/or production data, e.g., as used in the oil & gas industry. The graphing database can include multiple different entities that are defined by nodes, node edges, and properties that are generated from information collected by an exploration and/or production system. Entities can be designated as complete when the attribute data associated with those entities satisfy mapping rules for standardizing different types of entities. In this way, end users that access data from the graphing database can receive complete data that is consistently available through a variety of sources.

An in-wall feature detection device of mutual capacitive technology comprises a housing, a detection baseplate, and at least one capacitive sensing baseplate. The detection baseplate is disposed in the housing and has a central processing module and a capacitance value conversion module and is electrically connected to at least one display module. The capacitive sensing baseplate is provided with driving modules and receiving modules, the driving and receiving modules are arranged in a crisscross manner and electrically connected to the capacitance value conversion module. The in-wall feature detection device is capable of using an electric field change between the driving and receiving modules to determine whether there is a blocking object in a wall, and further generating a corresponding light signal through the central processing module to display a shape of the blocking object. Thereby determining a position and the shape of the blocking object during construction.

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.

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.
