Abstract
A fracture network mapping system can include a sensor, a repeater, an acoustic signal generator, and a distributed acoustic sensing system. The sensor and the repeater can be positioned in a fracture of a well. The acoustic signal generator can be positioned in a wellbore of the well. The distributed acoustic sensing system can communicate location data of the sensor from the repeater and the acoustic signal generator to a processing device for mapping the fracture.
Claims21
A fracture network mapping system comprising:
- a sensor positionable in a fracture of a well;
- a repeater positionable in the fracture;
- an acoustic signal generator positionable in a wellbore of the well;
- and
- a distributed acoustic sensing system for communicating location data of the sensor from the repeater and the acoustic signal generator to a processing device for mapping the fracture.
2 more elements
A method comprising:
- receiving, by a repeater positioned in a fracture in a well, a first signal from a sensor positioned in the fracture, the first signal representing a location of the sensor;
- transmitting, by the repeater, a second signal representing the location of the sensor in response to receiving the first signal;
- receiving, by an acoustic signal generator positioned in a wellbore of the well, the second signal;
- transmitting, by the acoustic signal generator, an acoustic signal representing the location of the sensor in response to receiving the second signal;
- detecting, by a distributed acoustic sensing system positioned at least partially in the wellbore, the acoustic signal;
- and
- mapping, by a processing device communicatively coupled to the distributed acoustic sensing system, the fracture using the location of the sensor.
4 more elements
A proppant mixture comprising:
- a sensor;
- and
- a repeater, the proppant mixture being positionable in a fracture in a well for wirelessly communicating with an acoustic signal generator in a wellbore of the well to acoustically transmit information about the sensor for receipt by a distributed acoustic sensing system at least partially in the wellbore.
