Abstract
This thesis endeavors to define the reservoir characteristics, stratigraphy, facies architecture and their relationships of the Lower Cretaceous Cardium Formation in the northeast Pembina Oil Field of west-central Alberta. Bioturbated lower shoreface to offshore sandstones are subdivided into two separate depositional units. The lower depositional unit is characterized by four stacked shoreface-offshore parasequences (A – D), and the upper unit consists of two sandspit parasequences (E – F). The units are separated by an erosion surface that eroded the uppermost deposits of the underlying shoreface – offshore parasequence. Characterization of the low permeability Cardium reservoir facies indicates that the horizontal and vertical sand-filled burrows improve sandstone bed connectivity and enhance permeability flow pathways. Subsurface reservoir mapping coupled with facies characteristics and production data established a more thorough understanding of the reservoir characteristics and fairway widths of unconventional low permeability offshore deposits.
