Abstract

In this paper, the results of investigation on detonation properties of heterogeneous mixtures of ceramic proppants with slurry liquid explosives (LE) such as nitromethane (NM) plus ammonium perchlorate compositions are presented. The mixtures discussed are promised to be used for far field fracture stimulation of oil bearing formation subjected to hydraulic fracturing. Experimental results on detonation velocities of LE-proppant mixtures in long tubes up to 25 diameters versus internal diameters are presented. Results of experimental comparison of detonability of LE studied with pure NM in proppant matrix are also represented. The objective of the study was to assess detonability and detonation parameters of these mixtures at various initial conditions.
