The M-66 well flowed gas from the "A" and "B" sands at a measured rate of 5.86 million standard cubic feet per day (mmscf/d) and a flowing wellhead pressure of 2067 pounds per square inch (psi) at the end of a 62.5 hour flow period. The well was flowed through a 7.7 millimeter choke and was still cleaning up after recovering 35% of injected completion fluids during the test period.
Fraccing and testing operations are planned to be conducted in a total of seven wells during August and September, and Corridor intends to continue to provide updates on the results of these activities as they proceed. Corridor considers the initial three wells (M-66, K-66 and J-66) to be the most productive of the seven wells to be stimulated and tested this summer, based on log evaluations and sidewall core analyses.
Potash Corporation of Saskatchewan and Corridor are joint participants in the M-66 well. Corridor also reported on recent re-test results for the four McCully wells (C-67, G-67, O-66 and K-57) that were fracced and initially tested late last fall. The re-test results showed significant improvement relative to the rates reported in December, 2005. The following table re-states the test results for the four wells reported last December as well as a productivity index which allows the wells to be compared on an equivalent basis.

The following table presents the flow performances for the retesting of these wells undertaken in July. Also shown are the percentage increases in the well productivity indexes after 4 days of measured (or projected) flows. It is important to note that these initial productivity indexes will continue to decline somewhat until steady state flow is achieved, which could take a year or more of continuous production for these relatively low permeability reservoirs.
