... that supercritical carbon dioxide fracturing fluid is greatly affected by temperature and pressure. The greater the viscosity of fracturing fluid during injection, the greater the resistance of fluid in the formation, and the slower the fluid loss rate. contributions of the work. Introduction With the progress...

... with the field data. A total of three types of variable orthogonal combinations of 7 kinds of viscosities of fracturing fluid, 5 kinds of injection rate and 8 kinds of thicknesses of barrier layer were carried out to explore the penetration feasibility of hydraulic fracture under the commonly used combination...

..., it is viscosity dominated (Lecampion et al, 2017). In addition, when this fracture is created in permeable and porous rocks, in which there is fluid loss into the rock, these regimes are converted to toughness-leak off dominated and viscosity-leak off dominated regimes respectively (Detournay, 2016). fluid...

ABSTRACT: The viscosity of fracturing fluid is the key parameter that can affect hydraulic fracturing. The fracture width is determined by the viscosity of the fracturing fluid...

... distribution law in the wellbore/cluster system. Then, sensitivity analysis of different pumping rates, fluid viscosities, proppant sizes, and proppant densities was performed to find out the proppant placement. It is found that all cases have a heel bias, and flow rates reduction and uneven distribution...

... reservoir area; single fracture injection of 60 tons CO 2 and shut in time of 15 days can achieve good results in reservoir development. For refractured well, CO 2 + fracturing fluid is preferred due to low viscosity of CO 2 and weak capability to propagate the fracture. chemical flooding methods...

... was studied respectively. Also, the characteristics of fractures created by CO 2 was compared with water. The results show that the bedding planes of thin interbedded rock is easy to be opened by low viscosity of CO 2 and the vertical fractures intersecting with bedding planes build complex fracture network...
