The Effect of Different Hydraulic Fracturing Width to the Well Production

By applying high pressure to tight formations like shale, a fluid, proppant, and additives create fractures or widen already existing ones to facilitate the flow of hydrocarbons into the well bore and ultimately to the surface facilities. Fracking, as hydraulic fracturing is more popularly known nowadays, is primarily utilized to produce hydrocarbons. The hydraulic fracturing fluid's proppant makes sure that once cracks are formed, they do not immediately seal, allowing hydrocarbon to gradually flow out of the tight formation. The additives are made up of several chemical types, and each one of them improves a particular quality of the fluid needed for the hydraulic fracturing process to be successful. In order to produce the desired amount of gas from unconventional reservoirs like tight gas, shale gas, coal bed methane, or other very low permeability reservoirs, an efficient hydraulic fracturing design is essential. Numerous elements need to be taken into account while developing and carrying out a hydraulic fracturing operation. These variables may also include flow back and shut in period, depth and thickness of reservoir, microcosmic events, the faults and natural fractures, which can play a significant role depending on reservoir properties, rock properties, type of reservoir fluids, etc. These variables are not only limited to pump rate, size and concentration of propping agent, fracture spacing or number of fractures, fracture geometry and conductivity, fracture length, and fracture width. These factors can differ greatly depending on where you are in the world. Without a thorough examination of underground formations holding hydrocarbons, there is no global hydraulic fracturing technique that can be used anywhere in the world.
