A method and apparatus for creating inverted laterals or drainholes for producing from a subterranean reservoir including the steps of lowering, positioning and securing a reverse whipstock in a wellbore. A tube is secured from the surface to a pull tube which extends through and below the reverse whipstock. Fluid is pumped from the surface and through a U-tube device below the pull tube. At least one inverted drainhole is drilled using force from the pumping fluid. The pull tube is pulled upward vertically toward the surface while pumping the fluid.
