EVALUATION OF BRITTLENESS INDEX FOR PALEOGENIC SEDIMENTS OF CENTRAL AND EASTERN CAUCASIA
(Ryzhkov V.I. Varov Yu.E. )
One of the most important parameters affecting the successful implementation of hydraulic fracturing in unconventional and low-permeability reservoirs is rock brittleness. Obviously, the definition of brittleness and the quantitative calculation of this parameter is still not clear. The paper provides an overview of methods for determining the brittleness index and selected the most effective of them for deposits of the paleogene system of the Central and Eastern Caucasia. We proposed a method for applying the results to predict sweet spots and intervals for development.......
