Abstract
A method for transmitting acoustic signals from pingers. The method includes transmitting acoustic signals from a first group of pingers within a seismic spread. The method includes transmitting acoustic signals from a second group of pingers within the seismic spread after a predetermined amount of time has passed, wherein the signals from the first group and the second group are emitted between two seismic shots. The first group of pingers and the second group of pingers are mutually exclusive.
Claims20
A method, comprising:
- transmitting acoustic signals from a first group of pingers within a seismic spread;
- and
- transmitting acoustic signals from a second group of pingers within the seismic spread after a predetermined amount of time has passed, wherein the signals from the first group and the second group are emitted between two seismic shots;
- and
- wherein the first group of pingers and the second group of pingers are mutually exclusive.
2 more elements
A method, comprising:
- deploying a first group of pingers within a seismic spread, wherein the first group of pingers are assigned a first code;
- deploying a second group of pingers within the seismic spread, wherein the second group of pingers are assigned a second code that is different from the first code, wherein the distance between pingers in the second group is greater than the distance between pingers in the first group;
- and
- wherein the first code and the second code are different codes.
1 more element
A method, comprising:
- deploying a set of pingers within a seismic spread, wherein the set of pingers are divided into a first subset and a second subset that are mutually exclusive of each other, wherein the first subset and the second subset are divided based on acoustic propagation of the area in which the seismic spread is located;
- and
- transmitting acoustic signals from only the first subset between two seismic shots.
