Abstract
This thesis focuses on two areas for successful placement with a channel fracturing technique: one in Wild River multiple formations with casehole completion and the other in cardium openhole multiple stages completion. This thesis is an attempt to analyze why channel fracturing can actually reduce a screenout rate. To do so, the thesis starts with both conventional and channel fracturing introduction, fracturing mechanism, and fracturing geometry simulation. The proppant transport mechanism horizontally and vertically is carried out to better conclude the condition that proppant can be transport without settling and bridging. Different causes of screenout are illustrated in detail. An analysis on why channel fracturing helps to reduce the screenout rate and increase successful placement is performed theoretically and then the theory is illustrated with all jobs pumped in Canada so far without screenout. Channel fracturing by itself has advantages over conventional fracturing to ensure successful placement.
