Improving LWD Image and Formation Evaluation by Utilizing Dynamically
Corrected Drilling-Derived LWD Depth and Continuous Inclination and Azimuth
Measurements
Abstract:fax 01-972-952-9435.
AbstractThe paper illustrates the improvements in logging while drilling (LWD) images and subsequent formation evaluation by utilizing a new methodology for depth and survey measurements correction. LWD depth measurements are often considered inaccurate and therefore not as reliable for well-to-well correlations, correlations to offset data acquired with wireline measurements and formation layer thickness determinations. The reasons for these inaccuracies generally originate from the tradi… Show more
