This study presents a hydrogeological evaluation of the Debolt Formation in the Trutch and Fort Nelson areas of northeastern British Columbia. The purpose of the evaluation is to produce a comprehensive analysis of the major play types, their trends and further potential. The integration of hydrodynamics and geology has allowed the definition of regional aquifer systems, distribution and characteristics of formation waters, structural and porosity trends, fracture distribution and production trends. On the basis of the regional analysis, the exploration and development potential of the area has been evaluated, with the focus on delineating prospects.
