Big Sky Petroleum Drills the Midboe 4-3 Science Well

Big Sky Petroleum Corporation (TSX VENTURE:BSP) - The Midboe 4-3 Science Well
has been drilled to total depth. The well was drilled to determine the reservoir
characteristics of the Bakken and Three Forks formations. The well was intended
to determine the prospectiveness of the eastern flank of the Kevin Dome and the
information will be included in our revised geological model, which will
determine our future geographic area of interest. 


The 81-4 Well, located in Glacier County, Montana, is expected to receive
permitting approval in Q2. The Company plans to drill a 4,500' pilot hole to
test the Middle Bakken. Based upon results of the vertical test, a 3,500'
horizontal leg is planned for the Middle Bakken. Frac design, stimulation and
completion programs will be concluded after all well data has been processed and
evaluated. 


The Somont 14-29 Well is still being tested and evaluated. The evaluation from
this well will determine the horizontal drilling and completion program for the
Somont 15-13 Well, which has been drilled vertically and awaiting completion. 


Bill Stelzer, Big Sky's Senior Geologist, has commented that "we continue to be
optimistic with our results. We have encountered oil saturated formations in our
objective targets and we are awaiting a complete engineering evaluation of the
14-29 horizontal well bore."
