Abstract:
A seismic acquisition system includes a seismic sensor tool for collecting seismic data and an external tool for coupling to the seismic sensor tool to provide energy. The seismic sensor tool includes a base plate and the external tool includes an inductive coil part. The base plate is energized by the inductive coil part through an inductive process to generate heat for melting ice or snow or frozen ground in contact with a housing of the seismic sensor tool.
Abstract:
A seismic data acquisition system includes a recording unit to record acquired seismic data and ground equipment containing surface units and wireless field digitizer units. Each surface unit is in communication with the recording unit and contains a first wireless communication module and a power supply mechanism transmitter coil. Each wireless field digitizing unit includes a seismic sensor unit, a second wireless communication module in communication with the seismic sensor unit and one of the first wireless communication modules to exchange digital data between the first and second wireless communication modules and a power supply mechanism receiver coil. The power supply mechanism receiver coil is magnetically coupled to the power supply mechanism transmitter coil in one of the surface units to transmit electrical energy wirelessly from the surface unit to the wireless field digitizer.
Abstract:
System, apparatus and method for collecting data from, and providing power to, a geophysical data acquisition device are described herein. The method may include charging a data transfer device comprising a data transfer port, a power transfer port and a battery module, coupling the data transfer device to a geophysical data acquisition device, deploying the geophysical data acquisition device and collecting data therewith, collecting data from the geophysical data acquisition device via the data transfer port and providing power to the geophysical data acquisition device via the power transfer port, replacing the data transfer device with a charged device, coupling the data transfer device to a charging station, transferring data from the data transfer device, and transferring power to the data transfer device via the charging station.
Abstract:
An apparatus for in situ geophysical sensing includes a sensor for measuring geophysical data and a liquid absorbent member connected to the sensor that expands in response to contacting a liquid and thereby physically couples the sensor to a local sensing environment. The liquid absorbent member may be formed of beads or pellets or powder that includes a liquid absorbent material. The liquid absorbent member may also include a soluble binding agent for binding the beads or pellets or powder into an integral member such as a casing for containing the sensor. A method and system corresponding to the apparatus are also described herein. The apparatus, method and system described herein may be used to improve borehole sensor data quality without adding significant complexity to the borehole sensor deployment process.
Abstract:
A portable charging system has a first part with an electrical power source and a first housing having a first three dimensional shape. A second part that is separate from and independent of the first part has a second housing with a second three dimensional shape comprising a complementary shape to the first three dimensional shape and a charge storage unit containing an ultracapacitor. The charge storage unit is disposed in the second housing. The first three dimensional shape mates with the second three dimensional shape to align the first part with the second part to facilitate wireless transfer of power from the electrical power source to the charge storage unit for storage in the ultracapacitor.
Abstract:
Systems and methods for wireless data acquisition in seismic monitoring systems are disclosed. The method includes obtaining a signal table for an emitted seismic signal, receiving seismic signal data from a receiver configured to transform seismic signals into seismic signal data, and storing the seismic signal data on a storage system. The method also includes determining a time span for the seismic signal data and generating a reduced data set based on the seismic signal data, the signal table, and the time span.
