WebThe Woodbend group of Upper Devonian age in central Alberta is composed of a reef complex characterized by large-scale facies changes. The reefs, which grew in a subsiding basin, were initiated in restricted areas of suitable water depth. They are surrounded by the calcareous shales and argillaceous limestones of the Duvernay and Ireton formations. WebIreton Formations have very different geomechanical properties than the Duvernay units, and variation is seen within the Duvernay units themselves. Three types of natural fracture fabrics were observed in the Duvernay core: bedding parallel parting (induced by removal of the core from confining stress), polished slip faces (and associated low-grade
WebIn the Woodbend Group of central Alberta, shales of the Ireton Formation occupy the basinal areas between the Leduc reefs. Within the shales are thin limestone beds which can be traced as electric-log markers over large areas. These markers probably approximate time lines, and they show a distinct westward divergence from the Ireton-Nisku contact.
