Abstract

The lowering of the original or natural permeability of the reservoir rock close to the well bore is referred to as “formation damage.” Additionally, it can be described as any kind of procedure that lowers the productivity of an oil, water, or gas bearing formation. Production, drilling, hydraulic fracturing, and work over operations are just a few of the steps of recovering oil and gas from reservoirs that can result in formation damage, an unfavorable operational and financial issue. A well stimulation method used to raise well productivity is hydraulic fracturing. This method helps to transfer the crude oil and natural gas through the pores and artificially develops channels to the production well because they are stuck at specific locations in the rocks. The oil and gas are extracted from the well and delivered to the surface for further utilization. Fracturing fluid, also known as pumping fluid, typically created by mixing water and sand and injecting it under high pressure into the formation when using the hydraulic fracturing process. There are certain activities that cause damage near the wellbore which lead to reduction in productivity. The drilling operation itself causes damage to the formation as the solids and fluids of the drilling fluids, as well as the fines produced due to the drilling operation, invade the formation and reduce the formation permeability and the ability of the oil and gas to flow to the wellbore. Hydraulic fracturing improves the productivity by creating a conductive path into the reservoir. The length of hydraulic fracturing influences to the production of well. As well as length of hydraulic fracturing increases, oil and gas production from well is increasing. After some point of length, it does not influence to the production of well.
