... treatment efficiency. Introduction Acidized fracturing is an stimulation technique for oil and gas fields with the aim of increasing the production from a well. An acid is pumped at a pressure above the parting pressure of the rock such that the formation is hydraulically fractured. The acid reacts within...

... to confining load variation. Therefore, it is very important to establish the relation between the stress-strain of the jointed rock mass and the reservoir permeability. This relation is particularly important to model hydraulic fracturing and productivity decline in tight gas wells. In this paper, a new...
