Abstract
A method for stimulating a wellbore penetrating a solid carbonaceous subterranean formation by positioning a hydrajet in an uncased portion of the wellbore penetrating the formation; perforating the formation with the hydrajet; and producing carbonaceous fluids and particulates from the formation through the wellbore and, thereby, forming a cavity in the formation surrounding the wellbore.
