ABSTRACT:
A method and apparatus for fracturing and propping a fracture interval wherein a workstring is lowered into the wellbore and a fracturing slurry comprised of a fracturing fluid and proppants is flowed down the workstring to a downhole slurry splitter which separates a portion of the fracturing fluid from the slurry and delivers it to the bottom of the fracture interval to initiate and propagate a fracture in the interval. The remaining slurry including the proppants is at the same time delivered to the top of the interval to prop the fracture as it is being formed. Alternate flowpath(s) deliver fracturing fluid and/or slurry to different levels within the interval to by-pass any sand bridges which may be formed during the fracturing operation.
