Abstract
Official abstract text for this publication.
A technique provides a methodology for improving surveys of subterranean regions. The methodology comprises estimating macro anisotropy and an intrinsic or micro anisotropy of an overburden. A surface electromagnetic survey is conducted, and the data from the survey is inverted based on or including information gained from estimating the macro anisotropy and/or intrinsic anisotropy. A processor system can be used to conduct the inversion with the adjustments for anisotropy to improve the information provided by the survey.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method, comprising: estimating a structure of reservoir layers and a spatial distribution of resistivity parallel to a bedding and perpendicular to the bedding along a trajectory of a well being drilled; conducting a surface electromagnetic survey; and improving an inversion of the surface electromagnetic survey through use of the values obtained by estimating the structure and the spatial distribution. 2 . The method as reci…
