Solution-gas reserves in Pembina Cardium oil field, Alberta, Canada
The Pembina field is the largest oil and solution-gas field in Canada, both in reserves and area. It has an area of 755,000 acres. The field, discovered in 1953, contained approximately 1.6 billion bbl of recoverable 37$API gravity oil and 1.2 trillion cu ft of solution gas. The oil and gas are present in sandstone of the Cardium Formation of Late Cretaceous age at depths ranging from 4,000 to 6,000 ft. The reservoir is a stratigraphic trap which resulted from the updip ''shale out'' of the sandstone. Local structure had little or no control on the accumulation. The Cardium Formation is divided into 5 units which are, in descending order: upper shale, conglomerate, upper sandstone, middle unit, and lower sandstone. The upper sandstone unit is the principal reservoir. It is a well-sorted, clean sandstone with good porosity and permeability. The conglomerate unit and stray sandstones, where developed, also contain some accumulations. Net pay thicknesses range from zero to 67 ft and average 13.9 ft. Average porosity is 12.2% and permeability is 24 md.
