... benefits of utilizing the zero-flaring flowback exceeds by far that of conventional flowback. This is because of capturing all the hydrocarbon produced during the flowback operation. The below table shows a comparison between the zero flaring and conventional methods. Table 1 Zero Flaring vs...

... The use of curable resin coated proppant (RCP) has proven to be a highly effective strategy for controlling proppant flowback. 8 , 9 RCP is made by applying a thermosetting resin to proppant substrate in a coating facility. Process conditions are controlled so the coating is adequately cured...

... 0 ) = ∂ ( ϕ m ρ g ) ∂ t Abstract Analysis of fracturing water flowback data from hydraulic fractures in unconventional reservoirs plays an important role in determining key fracture properties and predicting future well performance. Current flowback data...

... the optimum soaking time between the cessation of pumping, and the flowback of hydraulic fracturing fluids after a hydraulic fracture stimulation job, to increase productivity of shale gas and oil wells. Multiple cracks were observed at the surfaces of cores from a shale oil reservoir under simulated water...

... permeability to hydrocarbon ( k ro ). This study provides insight into the pore-scale evaluation of the latest flowback enhancer technologies currently applied in the Permian Basin, Texas, USA. A multidisciplinary approach, including concepts of nanotechnology, was used to assess fluid-fluid and rock-fluid...

... Abstract Highly efficient multi-stage hydraulic fractured horizontal wellbores are the dominant completion method for many basins worldwide. One potential weakness of multi-stage hydraulic fracturing is that the later stages of the completion workflow – frac-plug drill out (FPDO) and flowback...

... productivity from low permeability reservoirs. Hydraulic fracture characterization is a key to reliably evaluate fracturing operations and predict long-term reservoir performance. Flowback data analysis provides an early opportunity to do this. Abstract In this study, we propose a new method...

... and Definitions Post Fracturing flowback methods have varied dramatically over the years. Fracturing treatments were once remedial stimulation for old wells and were small in size. As fracturing techniques became more complex and formations became tighter, higher volumes of proppant was pumped...

During these operations, the hydraulic fracture system experiences major changes in pressure and flowrate, which may affect the well's long-term productivity. Among the many mechanisms responsible for decrease in well productivity, we highlight 1) the risk...

... such example is the operational difficulty and costs incurred in dealing with proppant flowback after fracturing operations are completed. In many such cases, a post-fracture cleanout is required before turning the well over to production, and subsequent additional cleanouts can be required after three to six...

Additionally, the recovered fluids’ calculated chlorides help define the load fluid flowback and the mixing of frac and reservoir fluids...

... of scale formation in the wellbore. Sulfate concentrations can be reduced by mixing AMD with flowback, which has high concentrations of barium (Ba 2 +) and strontium (Sr 2 +). Sulfate will react with the barium and strontium to precipitate barite (BaSO 4 ) and celestite (SrSO 4 ) which can be removed from...
