CHANNEL RESERVOIRS AND ASSOCIATED DEPOSITS OF WESTERN CANADA

Channel reservoirs are difficult to find and understand but offer assets with high economic impact to those firms successful in exploring for and developing them. In addition to forming prolific reservoirs, channel fills and related deposits also are important in aiding petroleum entrapment within flanking non-channelized units. Furthermore, the complex architecture of some channelized deposits creates tortuous fluid flow paths within reservoirs, which greatly influences reservoir development schemes like water flooding, EOR, horizontal well trajectories and perforation programs.

There are several different types of channel fill deposits located within the subsurface of western Canada, and the complex stratigraphy and sedimentology of these units mandates a sophisticated knowledge of the rocks forming both reservoir and non-reservoir strata. The Petrel Robertson 2-day core seminar on channel reservoirs and associated deposits exposes participants to a large spectrum of productive, prospective and trapping strata found in units ranging in age from Devonian through Upper Cretaceous. It augments the Petrel Robertson field seminars on modern fluvial (southeastern B.C.) and estuarine (Willapa Bay, Washington) systems and ancient Cretaceous channelized units exposed in Montana. During the course of the core seminar, participants will review deposits of braided, meandering estuarine and anastomosed systems. They will observe channel fill, point bar and crevasse-splay reservoirs, trapping units in tight channel fill sandstone and mudstones, and reservoir heterogeneities associated with non-reservoir interbeds and intraformational breccia. In addition to the ‘hands-on’ experience with cores, participants will receive lectures that describe channelized reservoirs in a multidisciplinary fashion, and place the units studied within a regional paleogeographic context.
