Abstract
An example method for distributed sensing in a subterranean formation may include drilling to a first depth in the subterranean formation using a drilling device and detaching a first phase of the drilling device at the first depth. The first phase may include a first coil of line and a first sensor. The drilling assembly may drill to a second depth and decouple a second phase of the drilling device, with the second phase including a second coil of line and a second sensor. Measurements may be generated at the first and second depths using the first and second sensors, respectively.
Claims20
A multi-phase drilling device, comprising:
- a first phase comprising a first coil of line and a first sensor;
- a second phase releaseably coupled to the first phase and comprising a second coil of line and a second sensor;
- and
- a drill bit coupled to the second phase.
A method for distributed sensing in a subterranean formation,
- drilling to a first depth in the subterranean formation using a drilling device;
- detaching a first phase of the drilling device at the first depth;
- drilling to a second depth in the subterranean formation using the drilling device;
- detaching a second phase of the drilling device at the second depth;
- and
- measuring at least one of an electromagnetic, acoustic, and seismic signal with at least one of the first phase and the second phase.
