There has always been
much interest in channel sandstone reservoirs both as exploration targets and as enhanced oil
recovery development sites. In order to understand these deposits one needs to appreciate the
depositional dynamics and the distribution of the several sub-environments associated with fluvial
sediments. Ideally one should be exposed to both outcrops and modern systems. In outcrop one sees
the vertical and lateral variability, whereas observation of modern rivers gives insight into active
processes and sediment distributions at the surface.
Petrel's field seminar to the Great Falls area of Montana exposes participants to spectacular examples of Cretaceous channel fills in outcrop. The seminar presented here, to the Columbia River valley of British Columbia, complements the Great Falls trip in that the depositional processes associated with modern rivers are viewed.
Besides the obvious benefits to geologists, this field seminar should also be of interest to both geophysicists and reservoir engineers. Geophysicists will be able to see the relative scale, lateral continuity and complexity of channel fills and enclosing sediments. Engineers will observe the depositional processes associated with rivers and thereby get an appreciation of the number, type and extent of non-random heterogeneities found in fluvial reservoirs.
