Gas Migration in EBS and Geosphere (GMT)
Excavation of the EBS - Investigations from top of Layer 12

The scientific excavation programme started with the removal of the gas collectors system on top of layer 12.

High resolution geophysical logging was used to identify and variation in buffer properties through the EBS and techniques for sampling the sand/bentonite mixture were tested.
