... are called Perkins flat section. This is the foundational hypothesis and the mathematical model based on it is stated in the work ( PerkinsТ.К., Kern L.R., 1961 [7] ). The asymptotic behavior of the fracture widening is stated in R.P. Nordgren ( Nordgren R.P., 1972 [5] ). The theory gained its...

In this paper, to solve this equation for small times a mathematical model of hydrodynamic processes occurring in the well in the derivation mode. The resulting model accounts teamwork...

.... This circumstance defines the proposed model applicability range. Mathematical model We have taken the multiphase isothermal black oil model in 3D as the basis for our model [ 4 ]. The salt solution is considered as addition to the water phase, changing its density and viscosity. The mass conservation...
