AbstractA study was undertaken in the southeastern portion of the Great Slave Plain of the Northwest Territories to discover current hydrodynamic conditions in Middle Devonian formations. Apressure elevation chart, constructed from drill-stem test data, demonstrates one aquifer system because almost all points line up along an average water gradient of 0.47 psi/foot.
A potentiometric surface map indicates that flow is primarily to the northeast in the direction of Precambrian outcrop. A small area of apparently low hydrodynamic potential exists near Cameron Hills. Widely spaced potential contours over most of the area indicate near-uniform flow conditions. Excellent water recovery on drill-stem tests and core evidence indicate good permeability for the overall Middle
Devonian section.
Formation water salinity generally freshens to the northeast in the direction of Great Slave Lake and middle Devonian outcrops. Salinity varies widely near Cameron Hills.
