Research Objectives
The principal objective of this work is to characterize the elastic
anisotropic properties of clay-rich rocks for consolidation conditions
simulating compaction at depth. A novel consolidation cell containing
sets of ultrasonic transducers and a phased array has been designed
to allow measurement of the five transverse isotropy (TI) elastic
constants of a rock sample during compaction. During the testing
phase of this project, we will conduct a series of laboratory anisotropy
tests on clay-rich rock samples provided by our industry partners
from basins worldwide.
