Methods and systems for augmented geological service characterization are described. An embodiment of a method includes generating a geological service characterization process in response to one or more geological service objectives and a geological service experience information set. Such a method may also include augmenting the geological service characterization process by machine learning in response to a training information set. Additionally, the method may include generating an augmented geological service characterization process in response to the determination information.

An integrated logging instrument for coring and sampling includes a downhole main body and a ground system. The downhole main body is connected with the ground system through a long cable. The downhole main body includes a coring and sampling mechanism, a power mechanism and an energy storage mechanism. The coring and sampling mechanism includes a coring assembly for drilling cores and a pushing and setting assembly for downhole fixation. The power mechanism is arranged at an upper end of the coring and sampling mechanism, and includes a motor, a piston structure and a pump body. The piston structure and the pump body are respectively arranged at two output ends of the motor. The piston structure is arranged to provide suction power. The pump body is arranged to provide hydraulic power. The energy storage mechanism is arranged at a lower end of the coring and sampling mechanism.

A system for determining a well placement may include an analysis module. The analysis module, using a Bayesian Decision Network model, may perform a first assessment of data availability, saturation, fracture, and seismic data associated with a candidate area for drilling a first well, and may output a first probability that indicates a potential production level of the first well. The analysis module may perform a second assessment of offset, stress, thickness, and porosity data associated with a second, nearby well, and may output a second probability that indicates a potential production level of the first well if a lateral is placed in a layer and at a azimuth direction. The analysis module may perform a third assessment of tortuosity, washout, and porosity data, and a net-to-gross value associated with the first well and may output a third probability that indicates a completion type for the first well.

A mesh network system includes an electronic control unit. The electronic control unit selects determines a current motion state of a vehicle of a mesh network. The electronic control unit may calculates radio metric scores for network interfaces. The radio metric scores are weighted based on the current motion. The electronic control unit selects a desired network interface for communications between the vehicles based on the radio metric scores.

Systems and methods for automated filtering and normalization of logging data for improved drilling performance may enable smoothing and amplitude scaling of log data for meaningful comparison and analysis without scaling artefacts. The logging data may be collected from downhole sensors or may be recorded by a control system used for drilling. A computer implemented method may enable industrial scale automated filtering and normalization of logging data, including calibration to a known standard. In particular, the filtering and normalization may be used for stratigraphic analysis to correlate true vertical depth to measured depth along a wellbore.

A downhole electromagnetic logging tool comprises a transmitting system, a magnetic field sensor array and a control module. The transmitting system and the magnetic field sensor array are both connected to the control module. The transmitting system comprises an upper emission coil and a lower emission coil, which are respectively arranged above and below the magnetic field sensor array, for generating magnetic fields of opposite polarities, allowing the magnetic fields to be concentrated at the magnetic field sensor array. A casing generates a secondary magnetic field, which is received by the magnetic field sensor array to complete detection of the casing.

A vehicle antenna apparatus installed in a vehicle is provided. The vehicle antenna apparatus includes an array antenna including a plurality of antenna elements, and a processor configured to perform at least one instruction. The processor is configured to obtain, based on a sensing result of a sensor for sensing a position of a user riding in the vehicle, information about the position of the user, adjust, based on the information about the position of the user, a phase of at least one radio wave signal such that a position of a radiation pattern formed by the at least one radio wave signal output from the plurality of antenna elements and the position of the user riding in the vehicle vary from each other, and control the array antenna to output the at least one phase-adjusted radio wave signal.

An apparatus for protecting an entrance to a protected area comprises a magnetic sensor to measure an ambient magnetic field or gradient within a first zone of sensitivity at a non-magnetic sensor means adapted to detect the presence of objects within a primary detection zone, a signal processing circuit arranged in communication with the magnetic sensor apparatus and nonmagnetic sensor apparatus, and a warning device operable by an output signal from the signal processing circuit, the warning device adapted to provide an alarm. The signal processing circuit identifies temporal variations due to the movement of a ferromagnetic object within the ambient magnetic field and correlates them with instances in which the non-magnetic sensor means detects the presence of an object in its detection zone, and causes the alarm to operate in the event that the correlation is indicative of the presence of a ferromagnetic object in the primary detection zone. It also determines the direction from which an object is approaching the using signals from the non-magnetic sensor means and modifies the operation of the warning device dependent on the direction.
