This study aimed to maintain a consistent near wellbore stimulation across the lateral, thus focusing on uniform cluster efficiency. Increased cluster spacing appeared to decrease stress shadow effects reflected...

This would be accomplished by isolating depleted regions, maximizing cluster efficiency, decreasing the required stage count, and utilizing a practical treatment approach to maximize stimulation in the depleted and non-depleted sections of the wellbore. The authors...

... Abstract Numerical simulation of hydraulic fracture propagation is increasingly used to evaluate the effect of various mechanistic aspects (e.g., inclusion of poroelastic effects, proppant transport, etc.), and of several variables, on the result of a stimulation operation at varying scales...

First, we analyze measurements from the vertical section of the B3H fiber during the stimulation of the heel-most stages of B1H, B2H, and B4H. Second, we investigate measurements from the vertical...
