Title:
METHOD FOR JOINT INTERPRETATION OF MULTI-ARRAY INDUCTION AND MULTI-COMPONENT INDUCTION MEASUREMENTS WITH JOINT DIP ANGLE ESTIMATION
Document Type and Number:
WIPO Patent Application WO2004003593
Kind Code:
B1
Abstract:
Data are acquired using multi-array logging tool in a borehole having an angle of inclination to a normal to the bedding plane of earth formations. The multi-array measurements are filtered using angle dependent filters to give a filtered curve corresponding to a target one of the multi-array measurements using angle dependent filters. Correlation coefficients are determined for a set of possible dip angles and a relative dip angle is estimated from the correlation coefficients. This dip angle estimate together with bed boundaries obtained from the multi-array measurements are used for inverting multi-component measurements alone or jointly with multi-array measurements to refine the relative dip angle interpretation and give horizontal and vertical formation resistivity.
