Multi-Resolution Borehole Profiling |
摘要 |
Harmonics and subharmonics of acoustic measurements made during rotation of a sensor on a downhole are processed to estimate the location of the imager, and size and shape of the borehole. A piecewise elliptical fitting procedure may be used. These estimates may be used to correct measurements made by a standoff-sensitive formation evaluation sensor such as a neutron porosity tool.
