Abstract
The concept of stimulated reservoir volume (SRV) has been brought to the industry to stand for the shale formation areas that have been touched by hydraulic fracturing during treatment. It is a complex fracture system that allows low permeability shale plays to be productive. Recent research on shale play development has mainly focused on achieving a better understanding of the SRV system and its potential. This research aims to study SRV areas that are not well propped by conventional proppant and to quantify the contribution of these areas to the overall conductivity distribution. In addition, ultralight weight (ULW) proppant and clustered proppant fracturing are studied as they are two techniques that have potential to improve the production from SRV in shale plays. Fractures propped by conventional proppants, ULW proppants and clustered proppants were analyzed through laboratory testing. The fracture permeability architecture, the permeability from natural fracture to opened fracture and to fractures with low proppant concentration, were also studied. The different properties of ULW proppant in shale rocks were studied. A numerical model that could account for various controlling factors in clustered proppant fracturing was built. These results could act as insightful reference for field applications.
