Abstract
Official abstract text for this publication.
Measurements made by a multi-component induction logging tool may be corrected for tool eccentricity or the presence of a fracture in the earth formation. The corrected measurements may then be used in conjunction with a multi-array measurement to determine horizontal and vertical formation resistivity.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of evaluating an earth formation, the method comprising: making a plurality of multi-component measurements using a logging tool in a borehole in the earth formation, the multi-component measurements indicative of a resistivity property of the earth formation, the multi-component measurements being affected by a disturbance in the azimuthal direction caused by an eccentering of the logging tool; estimating from the plurality of the multi-component…
