... the depleted a substantial decline in performance. In one case it is reservoir, the reservoir surrounding the steam chamber and, shown that the heat stored in the chamber per cubic metre particularly with thin reservoirs, the overburden. With high of produced oil will be only 62 % of that for conventional...

... Abstract The production of synthetic crude oil results in large volumes of fine tails which will remain as a fluid indefinitely (MacKinnon 1989). The overburden overlying Syncrude's oil sand deposit is a Cretaceous clay shale that is characteristically very dry and exhibits a high plasticity...

... the cost of selective mining of the overburden for the purpose of obtaining dyke building material. Research is also directed towards the use of borehole mining technology thus greatly increasing the resource exploitable by mining methods. In the in situ area the two major cost areas are access...

... alternate concepts that could be employed to mitigate some of the above concerns. INTRODUCTION It is currently estimated that 25 billion barrels (1) of recoverable oil exists under less than 500 feet of overburden in the Athabasca oil sands region located in Northern Alberta, Canada (Figure 1). Because...

..., 168 mm diameter pipeline was ruptured 32 times under varied conditions. The experimental rupturing technique, the transient release rate, and the sensitivity to source configuration were evaluated. Parameters investigated included: overburden, windspeed, release angle, fracture length, rupture mode...
