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 ...
An integrated well data analysis for in-situ stress estimation
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2003)
In this paper we obtain in-situ stress information based on two methods. The first one consists in matching borehole deformations to the modelling of linear poroelasticity equations around a hole in a plate that is subjected ...
