Wireless communications associated with a wellbore
A subsea communication system includes devices in a wellbore and devices on a floor, where the devices in the wellbore and on the floor are able to communicate wirelessly with each other, such as through a formation.
1. A method for use in a subsea environment, comprising:
wirelessly communicating between electrical devices in a subsea wellbore and electrical devices proximal a sea floor through a formation;
sending, from a first one of said electrical devices proximal the sea floor, wireless signals into the formation; and
receiving, at a second one of said electrical devices proximal the sea floor, a portion of the wireless signals reflected from a reservoir in the formation for determining a characteristic of the reservoir.
2. The method of claim 1 , wherein wirelessly communicating through the formation comprises wirelessly communicating electromagnetic signaling through the formation.
3. The method of claim 1 , further comprising performing the wireless communicating during an exploration phase for determining characteristics of a reservoir in the formation.
4. The method of claim 1 , further comprising performing the wireless communicating during a drilling phase to provide feedback from the subsea wellbore.
5. The method of claim 1 , further comprising performing the wireless communicating while completing a subsea wellbore.
6. The method of claim 1 , further comprising wirelessly communicating between electrical devices proximal the sea floor.
7. The method of claim 1 , further comprising wirelessly communicating between electrical devices in the subsea wellbore.
8. The method of claim 1 , further comprising:
a third electrical device proximal the sea floor sending wireless signaling through sea water to a fourth electrical device proximal the sea floor; and
in response to the wireless signaling from the third electrical device, the fourth electrical device sending, through the formation, wireless signaling into the formation to test a characteristic of a portion of the formation.
9. The method of claim 1 , further comprising a sensor in the subsea wellbore sending measurement data in wireless signaling through the formation to a receiver proximal the sea floor.
10. The method of claim 9 , further comprising the receiver sending, through sea water, the measurement data in wireless signaling to another electrical device proximal the sea floor.
11. A subsea well system comprising:
a first electrical device for positioning proximal a sea floor;
a second electrical device for location in a subsea wellbore,
wherein the first and second electrical devices are adapted to communicate wirelessly through a formation separating the first and second electrical devices; and
a third electrical device and a fourth electrical device proximal the sea floor, the third electrical device to send wireless signaling through the formation to a reservoir in the formation, and the fourth electrical device to receive wireless signaling reflected from the reservoir.
12. The subsea well system of claim 11 , wherein the second electrical device comprises a sensor,
the sensor to send measurement data in wireless signaling through the formation to the first electrical device.
