Abstract

Oil and gas fields of Western Canada are classified into six types: the foothills type, the bioherm reef type, the biostrome reef type, the stratigraphic and structural sand type, the stratigraphic sand type, and the unconformity trap type. The main purpose of the classification is to facilitate a brief, simple description of the habitat of oil and gas occurrences in Western Canada. Examples of each type are listed and illustrated.

Abstract

The Turner Valley field is comprised of two Laramide structures, the Turner Valley and Millar- ville thrust sheets, the latter over-riding the down-plunging north extension of the former. The ancestral fold and age of accumulation are pre-Jurassic and pre-Blairmore. The reservoir rock is a dolomitic biostrome identified by the abundance of detrital crinoids et cetera which form the porous zones and provide source. This relationship between the early accumulation and the age of folding, together with the organic origin of the reservoir, is significant in prospecting for oil in the Mississip- pian rocks of the foothills.
