..., and flowback processes through a modified core flooding experiments designed for ultra-low permeability samples. The three surfactant solutions reduce the oil-water IFT and make the rock more water-wet. All solutions demonstrate non-emulsifying properties, and have mean particle size of less than 40 nm, which...

... rocks takes a few weeks to complete and is limited to the toe stage in horizontal wells. In this study, the traditional DFIT method is modified by flowback after pump-in to accelerate fracture closure and stress/pressure measurements, and is hereby referred to as Accelerated DFIT (ADFIT). An ADFIT...

The concern about SRV damage due to aggressive flowback strategies has led to a variety of heuristic flowback guidelines of "x psi/day" across various operators and shale plays. However, conservative flowback strategies may also result in productivity loss due to water...
