The croissant: a smaller, fluffier, flakier pretzel

While we have a working experimental directional DAS sensor (DDS) at Carbon Management Canada’s Newell County Facility, it is quite large (10x10m), and being horizontal and flat, has no way to record vertical component data (Hall et al., This volume). Logistically, we need a smaller sensor that can record vertical motion and is easier to bury for permanence and coupling. Testing has shown that we can record reasonably consistent data on a sensor where the one-meter-long sides of the sensor are smaller than the default seven-meter gauge length used in our DAS interrogator. In future, after further testing, we plan to install a receiver line containing more than one directional DAS sensor at the Facility.
