APPARATUS AND METHODS TO FIND A POSITION IN AN UNDERGROUND FORMATION |
摘要 |
Various embodiments include apparatus and methods related to finding a position in an underground formation. Apparatus and methods can include receiving signals from a receiver in an underground formation in response to signals generated from transmitting sources, each of the transmitting sources located at a known position; and processing the received signals, based on the signals generated from the transmitting sources, to determine the position of the receiver. A number of techniques can be applied to processing the received signal. Additional apparatus, systems, and methods are disclosed. |

1. A method comprising:
receiving signals from a receiver in an underground formation in response to signals generated from three or more transmitting sources, each of the three or more transmitting sources located at a known position, at least one transmitting source of the three or more transmitting sources separated from and mounted on a structure different from at least one other transmitting source of the three or more transmitting sources; determining angles with respect to the transmitters relative to the receiver based on the received signals; and determining a position of the receiver based on the angles and the known positions. |
