Based on the experimental and field data, fracturing fluid flowback rates and gas production rates of, 9 wells, were analyzed. It is indicated that the same block follows an overall trend, namely, the lower the flowback rates, the more developed the micro fractures, the better the volume simulation effect and the higher the gas production rates.

Guar-based ,fluid fracturing, systems comprise 25% of this study with an average ,flowback, time of 231 hours with 30% (at most) ,fluid, recovery. On the contrary, 75% of the treatments used a ,low,-residue polysaccharide-based system, which required an average of 110 hours of ,flowback, time, while only 10% of the volume was recovered to deliver to production facilities because of the lack of water percentage.

16/4/2020, · If too much fluid leaks off, the fluid has a low efficiency, (10 to 20%),, and the created fracture volume will be only a small fraction of the total volume injected. However, if the fluid efficiency is too high (80 to 90%), the fracture will not close rapidly after the treatment.

Amplitude-versus-offset (AVO) inversion always plays an important role in reservoir ,fluid, identification, which allows the estimation of various rock and ,fluid, properties from prestack seismic data. In this paper, we propose a new method for discrimination of hydrocarbon accumulation that combines frequency-dependent AVO inversion scheme and variational mode decomposition (VMD).

Therefore, a new concept called, zero flowback rate, (ZFR) of HFF is put forward to serve as an unconventional way to manage the high volume of HFF. ZFR of HFF is a concept compared with the flowback rate of the fracturing fluid for a conventional reservoir. It is worth noting that zero in the ZFR concept does not stand for the absolute number 0.
