Abstract
A method is provided for processing marine controlled source electromagnetic data. Inline and broadside marine controlled source electromagnetic data are provided, for example by means of one or more horizontal electric dipoles and one or more receivers disposed in a water column above a subsurface to be surveyed. A linear combination of the inline and broadside data is formed so as to reduce the airwave content.
Claims16
A method of processing marine controlled source electromagnetic data, comprising the steps:
- providing inline and broadside marine controlled source electromagnetic data;
- and
- forming a linear combination of the inline and broadside data to reduce airwave content.
A computer program embodied on a computer-readable medium for controlling a computer to perform a method of processing marine controlled source electromagnetic data, the method comprising:
- providing inline and broadside marine controlled source electromagnetic data;
- and
- forming a linear combination of the inline and broadside data to reduce airwave content.
A computer-readable medium comprising instructions for performing a method on a computer of processing marine controlled source electromagnetic data, the method comprising:
- providing inline and broadside marine controlled source electromagnetic data;
- and
- forming a linear combination of the inline and broadside data to reduce airwave content.
An apparatus comprising:
- a computer programmed by a computer program embodied on a computer-readable medium for controlling the computer to perform a method of processing marine controlled source electromagnetic data by:
- providing inline and broadside marine controlled source electromagnetic data;
- and
- forming a linear combination of the inline and broadside data to reduce airwave content.
A system for processing marine controlled source electromagnetic data comprising:
- a computer including at least one data processor;
- and
- a computer-readable medium programmed with instructions to cause the computer to:
- provide inline and broadside marine controlled source electromagnetic data;
- and
- form a linear combination of the inline and broadside data to reduce airwave content.
