Hydraulic fracturing treatments are accomplished to create a highly conductive flow path from the reservoir to the wellbore. Maximum success requires stimulating all perforation in the treated interval. However, performing such coverage is challenging in unconventional reservoirs because fracture opening pressures can vary widely within the perforated interval. A new fracturing service that employs an innovative diverting agent improves production from established fields and allows operators to develop areas that previously were not economically viable. HiWAY flowchannel fracturing technique specially increases fracture conductivity. It has also been proven to lower the risk of the screen out (premature job termination because of rapid pressure increase produced by a sudden flow restriction), allowing jobs to be placed more reliably. On average, the HiWAY fracturing technique increases production more than 20%, while usage 40% less prop pant. Moreover, compared with slick water treatments, the technique can use up to 25% less water. The result is higher short and long-term production, simplified logistics, a smaller operational footprint, and significantly reduced environmental impact. This paper is going to discuss about the hydraulic fracture process, reason of hydraulic fracturing, new technique i.e., HiWAY Flow-Channel Fracturing technique, and the results of two well stimulation treatment which was done through the HiWay flow-channel Fracturing technique, that proving the increase of oil production over extended periods even with decreasing reservoir pressure near wellbore.
