Well stimulation is an applied research field and set of engineering methodologies focused on enhancing the flow of hydrocarbons from subterranean reservoirs into production wellbores. This concept investigates various techniques designed to overcome reservoir flow restrictions, such as hydraulic fracturing and matrix acidizing, analyzing their effectiveness in increasing production rates and total hydrocarbon recovery. Its significance lies in enabling the economic viability of extracting resources from low-permeability and unconventional formations, driving research into optimal application strategies, reservoir response, and associated operational, economic, and environmental impacts.
