Abstract

Successful in-situ retorting of subsurface oil shale beds may depend on the ability to achieve sufficient permeability by explosive fracturing. To provide guidance in field experiments as to the type and amount of explosive; the number, size, and spacing of satellite wells; stemming and venting; and other criteria, it is necessary to obtain calculations of fracture damage. Thus, the objective of this research [1] was to develop a mathematical model for dynamic fracture of oil shale that could be used as a subroutine in wave propagation codes to compute the extent of fracture produced under given circumstances.
