... propagated in the area. This paper introduces a field case study integrating field test data such as a PBU (Pressure Build-up) survey in the parent well, aligned DFITs (Diagnostic Fracture Injection Tests) in the child wells, and flowback data after hydraulic fracturing in both the parent and child wells...

..., referred to as "parent" wells, negatively affect the production performance of subsequently drilled "child" offset wells due to reservoir depletion effects. While the production degradation resulting from parent-child well interactions is well established empirically, generating accurate quantitative...

... Abstract Well performance data across several US shale plays shows that child wells typically underperform relative to parent wells (parent-child effect). The Eagle Ford shale is known to exhibit some of the most severe cases of parent-child effect with up to 60% degradation in normalized...

... into the complex interactions between primary (parent) and infill (child) wells to maximize resource recovery. Better understanding of these interactions will enable operators to optimize production performance of child wells, preserve parent well EURs, formulate a completion design to use in the field, avoid...

... pressure drop, as well as fracture toughness in a few specific layers. Production and depletion observations were matched by adjusting a global permeability multiplier, relative permeability curves, and pressure-dependent permeability reduction with depletion. Only the toe sections of the child well(s...

... Abstract Inter-well Fracture Driven Interactions, aka FDIs, have gained visibility as more of high intensity events are observed in tightly spaced wells in unconventional reservoirs. Currently, the pressure response in the parent well during fracturing of the child well is often used...

... with the existence of the Diagnostic Fracture Injection Test or DFIT method to confirm the accuracy of this method in estimating each frac stage pressure gradient. This new method can be used to help minimize Fracture Driven Interactions (FDIs) between parent and child wells. This paper proposes a novel, low-cost...

This integrated model illustrates the changes in pressure and stress orientation as a direct result of voidage from un...

... Abstract The interaction between unconventional parent and child wells has gained a lot of attention over the past few years as infill drilling has increased. Despite numerous mitigation approaches, including pre-loading and recompletion of the parent well, de-spacing, and adjusting...
