In the world of unconventional oil and natural gas production, operators are constantly looking for new technologies that can help provide that extra edge. Among those technologies is the HiWAY flow-channel hydraulic fracturing technique, which improves the ability of fracture to deliver increased oil and gas production. The technique decouples fracture conductivity from proppant pack permeability by creating stable flow channels. A number of related and interdependent elements contribute to the success of the technology, including a specialized pumping technique, advanced fiber technology, completion strategy and engineering modeling. Specialized blending equipment and control systems are used to pump proppant in pulses at a high frequency within the fracture. The proppants help hold the fracture open, serving as columns for the channels to be developed around.
