Computer simulators of hydraulic fracturing rely on known physical properties of the
reservoir, in particular, the leak-off coefficient and the confining in situ stress. This�…

Hydraulic fracturing is an important part of modern technologies for intensification of
hydrocarbon production. The propagation of the hydraulic fracture is stimulated by the�…

The paper presents a method for calculation of closure pressure on hydraulic fractures on
injection wells as a parameter determining the beginning of fracture growth. The method is�…

The impact of poroelasticity effects on the fracture closure pressure p foc, breakdown
pressure pb, and reopening pressure p re, and their influence on the interpretation of in situ�…

In permeable rock the hydraulic fracturing stress measurement is carried out using such
impenetrable shell as a packer and a sleeve that prevents from fluid injection into the�…

In the paper a model for description of a hydraulic fracture propagation in inhomogeneous
poroelastic medium is proposed. Among advantages of the presented numerical algorithm�…

A computational algorithm is proposed for determining the acceptable range of bottom-hole
pressure based on a composite indicator diagram constructed from well test data analysis in�…

The study presents an analysis of the back-stress effect on precise determination of in-situ
stresses in a model samples in laboratory experiments on hydraulic fracturing. Main stage of�…

It is experimentally found that shut-in pressure conforms with the fracture initiation pressure if
the fracture surfaces are uniformly loaded by fluid. The article shows that equaling minimal�…

In the following work the method of unequal stress state estimation of rock massive is
numerically researched. This estimation is carried out by the fracture interval cross section�…
