The final reef configuration, conforming closely to the productive Acheson, Leduc, Glen Park, and Wizard Lake fields, is marked by intervening channels or saddles. Formation of the northeast and southeast reef extensions at the Leduc field is believed to have been...

... of the later hypersaline upper Nisku phase. Nisku pinnacle reef development in this area is primarily controlled by Leduc paleotopography, the pattern of Ireton Shale infill, and Camrose paleotopography. Through construction of a residual isopach map of the Leduc Formation using all available deep penetrations...

... at the onset of Mississippian deposition and reached its zenith during Debolt Formation deposition. During the early stages of this process, the Leduc reef had been a closed diagenetic system that limited the magnitude of differential compaction. Debolt age rapid subsidence induced faulting that extended...

... of the Ireton aquitard. In the southern part of the Rimbey-Meadowbrook reef trend, trapping conditions are slightly different with many Leduc reefs filled to capacity. However, some hydrocarbons must have migrated across the Ireton aquitard, because there has been scattered production from the Nisku Formation...

...J. G. Gray; W. A. Roliff ABSTRACT Exploration in Canada during the year was extremely active. The activity initiated in Alberta early in 1947 through the discovery of lucrative reef production at Leduc increased to major proportions in 1948. Exploration energies were almost entirely directed toward...
