Abstract A series of true axial hydraulic fracturing experiments were conducted to understand the complex fracture initiation and propagation behavior multilayered rocks. Moreover, a new convenient grid measurement method was presented describe effectiveness. The experimental results revealed that transverse vertical non-planar fractures could be created in area scanning by match indicated trad...

For horizontal well in low-permeability gas reservoir, the effects of threshold pressure gradient, stress sensitivity, and slippage have significant impacts on productivity. At present, there are few productivity formulas for considering all these factors. In this paper, based flow analysis whole field was divided into two parts, namely, far wellbore region near region, among which is composed ...
