The model for the express-estimation of the hydrofracturing design with the approximate analytical solution
Abstract
The paper provides an analytical solution for the Pseudo3D model for fracturing in a simplified geomechanical setting. The problem is solved in dimensionless parameters to ensure the universality of the solution. Dimensional lengths on height are plotted, as well as the Aspect ratio graph of the crack for different toughness. The existence of the global maximum Aspect ratio is shown. The obtained solution allows to quickly find the geometry of the fracture during the development, as well as to estimate the required volume of fluid injection to achieve the desired fracture length, including for hybrid fracturing with several liquids.
