... that the fractured well itself, while an improvement on the unfractured case, may still not be producing at an optimum rate, especially if there is damage in the formation, at the fracture face or in the proppant pack. An overall total “negative skin,” which arises naturally when characterising the fractured well...

... treatments were unsuccessful due to a reduction in the formation permeability due to the mechanical plugging and movement of the kaolinite or disrupted mica in the pore throats. The reduction in the matrix permeability results in skin damage in the faces of the fracture. The fracture-face damage or skin can...

... the effectiveness of a new method for enhancing and sustaining proppant pack conductivity. The approach uses an aqueous-based surface modification agent (ASMA) as part of the pad fluid stage to treat the fracture faces before placement of proppant into the fractures. ASMA treatment forms a thin film that becomes...

... fracturing, frac-packing, or gravel-packing. One new application made possible by emulsion delivery is the inclusion of the ASMA in the first fluid injected into a fracture, which coats the fracture face with a hydrophobic film. This film provides stability to soft formations, inhibits water invasion...

... Abstract In context of this work, a new formation damage mechanism is proposed: the mechanically induced fracture face skin (FFS). This new mechanism results from mechanical interactions between the proppants and the reservoir rock, due to the increasing stress on the rock-proppant system...

... increase. In the simulator, the internal formation damage and the external filter cake deposition in the fracture occur simultaneously. Two internal formation damage deposition models are taken into account. In a first model the internal damage is supposed to be linear and occurring from the fracture faces...
