Claim:
1. A method for stimulating a hydrocarbon bearing formation comprising: injecting a first fluid of a first composition and a second fluid of a second, different composition into the hydrocarbon bearing formation at a pressure sufficient to create or enlarge a fracture therein, wherein the first fluid is a cementitious fracture fluid comprising fibers dispersed in a cementitious medium; and curing the injected cementitious fracture fluid to form a permeable cement matrix comprising a continuous network of interconnected channels corresponding to the position of the dispersed fibers, the interconnected channels being configured for flow of the hydrocarbon therethrough; wherein the second fluid is substantially degraded or dissolved during or after said curing of the cementitious fracture fluid so as to form a plurality of open sections alternating with a plurality of sections of the permeable cement matrix.
