..., proppant and fluid frac compatibilities, and optimum spacing, are some of the challenges inhibiting successful hydraulic fracturing operations across the world. In this study, we aim to investigate the effects of varying fracture-cluster lengths, proppant types and sizes, and frac fluid types, on hydraulic...

... workflow. The work started from systematical laboratory fracture conductivity tests performed with fractured cores to measure conductivity versus confining stress for both natural fractures and hydraulic fractures (with proppant placed in the fractures of the core samples). Natural fracture modeling...

... such as high fracture initiation and treating pressures, risk of premature screenout, and conductivity degradation. A conventional fracturing treatment in such challenging environment necessitates increased polymer concentration in fracturing fluids and using smaller-size proppant at low concentrations...

... fracturing techniques, offers a tangible solution for increased productivity. The channels in the proppant pack are created through a patented technique that combines special pumping protocol, perforation scheme, fracturing fluid design and fiber technology. These conductive channels accelerate fracture...

... Fracturing Technique was considered as a solution to improve upon the production through creation of infinite production conductivity and greater effective contact area. This technique is similar to conventional proppant fracturing techniques where fluid and proppant are used to create conductive paths...

... for temperature ranges between 120-300+ °F. Field tests prove shear stability and good proppant transport at 20 BPM through a 1.25 in sliding sleeve baffle. The fracturing fluid system can be designed for instant or delayed crosslinking in recycle water with total dissolved solids exceeding 300,000 mg/L...

... Abstract The actual fracture conductivity contributing to gas flow after a proppant treatment is usually much lower than what is reported in the laboratory tests. This is because the ideal conductivity values can be impaired by numerous factors in the reservoir conditions – from high unconfined...

..., will determine the fracability and whether it is advantageous to use slickwater, linear gel, or crosslinked gel. Similarly, formation softening analysis using a Brinell hardness test and proppant embedment test will ensure that the formation does not close upon fluid treatment and will have conductive flow...
