A comparison of LWD and wireline dipole sonic data
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2004)
Data measured by both wireline and LWD tools in the same borehole are compared. Discrepancies in shear velocities as calculated from the data are on average around 5% and discrepancies between compressional velocities are ...
Elimination of LWD (Logging-While-Drilling) Tool Modes Using Seismoelectric Data
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2006)
Borehole acoustic logging-while-drilling (LWD) for formation evaluation has become an indispensable part of hydrocarbon reservoir assessment (Tang et al., 2002; Cittá et al., 2004; Esmersoy et al., 2005). However, the ...
