A method for fracturing and propping a thick and/or homogeneous fracture int erval (12) of a subterranean formation which is traversed by a wellbore (11). A workstring (20) is lowered into the wellbore (11) and a fracturing fluid is flowed into either or both ends of the fracture interval annulus (33a) (i.e. that portion of the well annulus which lies adjacent the fracture interval) to initiate a fracture (A). The flow of fracturing fluid is continued into one end of th e annulus (33a) while a slurry containing proppants is flowed into the other end of the fracture i nterval annulus (33a). During flow of fracturing fluid and slurry into the annulus (33a), slurry an d/or fracturing fluid is also delivered through alternative flowpaths (26) to different levels within said fracture interval (12). This is continued until all of the levels or zones of the fracture interval (12) have been fractured and propped.
