About this deal

S. Tong, C. Miller and K. Mohanty, Generation of In-Situ Proppant through Hydro-Thermal Reactions, in SPE Hydraulic Fracturing Technology Conference and Exhibition, Society of Petroleum Engineers: The Woodlands, Texas, USA, 2019, pp. 1–13 Search PubMed. g PX, 12 g VA and 2 g AN are added into the beaker and stirred until they are completely dissolved at room temperature (25 °C);

The mass changes and thermal behaviors of each raw material and green body were characterized using a thermogravimetric analyzer and differential scanning calorimeter (STA449F3, Netzsch, Germany) with a heating rate of 10°C/min under air atmosphere, and the test temperature range was from room temperature to 1300°C. 2.3.5 Morphological propertiesChen, J.; Wang, X.J.; Zhou, S.W.; Chen, Z.G. Effect of alkalinity on bio-zeolite regeneration in treating cold low-strength ammonium wastewater via adsorption and enhanced regeneration. Environ. Sci. Pollut. R. 2019, 26, 23–38. [ Google Scholar] [ CrossRef] g FS is added to the solution prepared in step (3), name the mixture liquid MX, and stirred until the self-suspending spherical ultra-low density proppant (UDP) particles are formed. 2.2 Fourier transform infrared (FT-IR) measurements The Fourier Transform Infrared (FT-IR) spectra of UDP and the liquid mixture before the generation of UDP are tested with a WQF-520A Fourier transform infrared spectrometer. The test method is as follows: drop the mixed liquid onto a piece of KBr sheet and spread it evenly on the sheet surface. The FT-IR test can be carried out using this sample. Use pure spectral KBr and UDP to prepare a mixture with the mass ratio (KBr : UDP = 50 : 1), mix it evenly, grind, and roll into thin slices. Their infrared spectrum is measured by a WQF-520A Fourier transform infrared spectrometer at room temperature. 2.3 SEM measurements The morphology of MX was investigated by an FEI Quanta 450 ESEM (environmental scanning electron microscope). MX was frozen using liquid nitrogen. The frozen surfaces of the samples were observed with ESEM operating at an accelerating voltage of 20 kV.
