As a preview to our upcoming October 2018 RECORDER, we present this abstract.
Shallow groundwater is often hosted in Quaternary sediments that are very complex in nature and challenging to map. Traditional mapping and exploration methods to delineate these features are often time consuming, costly, and provide uncertain results. Airborne electromagnetic (EM) techniques have proven effective in delineating these aquifers over extensive geographic areas in a very timely and cost effective manner.
Brion Energy Corporation (Brion), in collaboration with DMT Geosciences Ltd. (DMT), has employed these techniques to identify shallow groundwater sources near our assets. Once these sources have been located, more traditional methods have been employed to verify and assess the aquifers. Some paleo-channels are often complex in shape and can pose additional challenges when drilling. For these circumstances, additional relatively low-cost ground-based EM methods (Time-Domain Electromagnetics, or TDEM) can be applied to confirm a shallow aquifer drilling target to improve drilling and well testing success.
