The Elbow River Valley in the Weaselhead area in SW Calgary offers an interesting opportunity to examine a meandering fluvial system within a small, multi storied incised valley fill. The modern meander belt is on the order of 500m wide and cuts into older terrace deposits within the valley. Immediately downstream, a flood control dam has created the Glenmore Reservoir. Where the Elbow River enters the reservoir, a bayhead delta has formed.
The purpose of the field trip is to compare the architecture of these modern and recent sediments to examples of McMurray Formation meander belts. We will examine the point bars of the Elbow River, resultant textural and facies relationships as a result bank erosion, look at the size of distribution of oxbow cut offs and chute channel fills and note how sediment is accreted across the surface of the point bars. The trip will include examples of how point bar geometries and heterogeneities impact SAGD production. While there are obvious differences in grain size between these modern deposits and the McMurray examples, observing how sediment is actually accreted to the surface of the point bar is useful when contemplating grain size relationships in subsurface reservoirs.
Some Upper McMurray Formation incised valleys contain a similar architecture of fluvial terraces. By examining the geomorphic features of the modern river in the context of the meander belt of which they are a part, an attempt will be made to better understand the potential distribution of facies and resultant heterogeneities in architecturally similar ancient deposits.
We will also discuss flooding events in Calgary during the spring of 2013 and the response of modern point bars to high flow events. We will compare the flood characteristics of the nearby Bow River, which the Elbow River drains into at Fort Calgary. The two rivers responded to flooding differently. In the Bow, the flood water bypassed meander bends, and city streets situated on, and parallel to, the point bars essentially acted as chute channels. In the Elbow (with typically only one seventh the discharge of the Bow River), greater incision of a narrower channel constrained much of the flood waters within the main channel. Flooding occurred mainly in old portions of the channel that had previously underwent neck cutoff (dry oxbows) and other areas where bridge spans were clogged with debris and flooding of the adjacent overbanks occurred. Despite being a noteworthy event in Calgary’s history, we will discuss why little evidence of the flood will be imparted to the local rock record.
The Heavy Oil / Oil Sands Division was originally established in November 2007. The purpose of the division was to provide a forum for CSPG members and guests who are either employed and/or interested in learning more about the disciplines of heavy oil and oil sands. This division is focused on providing attendees the opportunity to learn more about the geology, technology, various projects and development in the heavy oil / oil sands industry. In addition, this forum will provide the attendee the chance to network with their peers and meet new contacts in the industry.
The division will host a breakfast session that will take place in the Halliburton Training Room which is located at Room 1830, 645 - 7th Avenue SW. The forum will start at 8:00am and starts with a 10 minute introduction, followed by a 40 minute talk, and will conclude with 10 minutes to network. We are looking for sponsors for our continental breakfast. The sponsor will get promoted on our group email as well as at the event. During the introduction each sponsor will be able to talk for up to 5 minutes about their company, services and products. The sponsoring company will also be able to provide a business card draw.
The monthly forum will be the first Wednesday of each month. We expect to host additional events throughout the year to allow our attendees the opportunity to do more networking. Some of these events include a Christmas party and Stampede party. The events will be complimentary and will be sponsored by various service companies engaged in the heavy oil / oil sands industry.
