Original Directive 027, Shallow Fracturing Operations—Interim Controls, Restricted Operations, and Technical Review January 31, 2006
The Alberta Energy and Utilities Board (EUB/Board) has approved this directive on January 31, 2006, original signed by M. N. McCrank, Q.C., P.Eng. Chairman
Information provided by industry to date shows that there may not always be a complete understanding of fracture propagation at shallow depths and that programs are not always subject to rigorous engineering design. … Effective immediately, licensees must not conduct fracturing operations at depths less than 200 m unless they have fully assessed all potential impacts prior to initiating a fracturing program.
