Open the CIPO recordAbstract From the Canadian patent
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 multiarray 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 multicomponent measurements alone or jointly with multi-array measurements to refine the …

Why it's free to use
- Filed June 26, 2003 and granted November 12, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 26, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 26, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
