CA 2711877

A stand-alone frac liner that allows for fracturing of multiple lateral legs of a multilateral well on a single call out and rig-up of fracturing equipment. Tools and techniques are provided that include setting multiple stand-alone frac liners in multiple lateral legs of the multilateral well. The liners may rest in the legs physically un- tethered to surface equipment. Thus, a single call out of a frac string tubular and associated equipment may be used to frac the lateral legs in sequence from one leg to the next. This may be achieved without the requirement of removal of the tubular from the well or disconnect of surface fracturing equipment between the lateral fracture applications. Thus, a considerable amount of expenses associated with time and manpower may be saved.
