This report is an update to a 1993 hydrogeological evaluation of the middle Devonian Slave Point Formation. The study area remains unchanged. It includes Townships 90 to 106 and Ranges 13 W5M to Longitude 121°, which covers the Sawn, Hotchkiss, Cranberry, Hamburg, Ladyfern and Paddy areas of northwestern Alberta and northeastern British Columbia. There has been an increased amount of interest in Slave Point exploration in this area since 1993. The majority of the interest has occurred in Chinchaga, Hamburg, and Cranberry regions as well as new discoveries.

The objectives of the original study were to:

• Determine the regional hydrostratigraphy of the Slave Point and its relation to the Gilwood Formation.
• Provide a regional geologic overview of the Slave Point.
• Determine regional fluid flow directions.
• Classify all hydrocarbon occurrences within a regional geologic and hydrodynamic context.
• Delineate potential exploration fairways.

The objectives of the update were to:

• Incorporate new data to extend original pool outlines and define new exploration fairways.
• Develop a better understanding of the relationship between the Slave Point and the Gilwood Formations.
• Investigate a possible relationship between temperature distribution, gas chemistry, and pressure profiles.

The updated study integrates hydrodynamic data with the original geological interpretation. Revised interpretations of hydraulic systems, reservoir continuity, fluid contact relationships, and potential exploration fairways are provided.
