| 发明名称 | Method of processing marine CSEM data | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method of processing marine controlled source electromagnetic data, comprising the steps of: providing inline and broadside marine controlled source electromagnetic data comprising inline and broadside electromagnetic field components; and forming a linear combination of the inline and broadside field components to reduce airwave content, wherein the inline and broadside data comprise inline and broadside electric data comprising inline and broadside electric field components, and wherein the step of forming the linear combination comprises forming a difference between the inline electric field component(s) and weighted broadside electric field component(s), the weighted broadside electric field component(s) being weighted by a first weighting factor. | ||
