Abstract

Summary

We used resedimentation and constant rate of strain (CRS) compression tests to study the compaction and permeability evolution of material derived from Plio-Pleistocene aged mudrock from the Eugene Island Block 330 oilfield, offshore Louisiana. We compare our results to previously published in-situ data derived from well logs and to previous tests of intact core. We find remarkable agreement in both compression and permeability behaviour between our resedimentation experiments and intact measurements. Resedimentation provides a systematic approach to understanding mudrock behaviour at high effective stresses. The correlation between in-situ measurements and resedimented results allows us to derived characteristic compression and permability behaviour for Gulf of Mexico mudrocks. These results suggest that there has been little diagenesis or other ageing processes that have occurred in these mudrocks even though they have been buried to more than 3,000 m.
