wellstimulation
Wellstimulation refers to a set of techniques used to increase or restore the flow capacity of a well by enhancing the permeability of the surrounding reservoir near the wellbore. It is commonly applied in oil and gas production, but is also used in geothermal wells and, in some cases, water wells. Stimulation aims to counter production declines caused by damage, fines, or naturally low permeability.
The main categories of well stimulation are hydraulic fracturing, chemical stimulation, mechanical stimulation, and thermal stimulation.
Design and evaluation of wellstimulation depend on rock type, damage mechanisms, and fluid properties. Treatments are
Regulatory and safety concerns accompany wellstimulation. Potential risks include induced seismicity, groundwater contamination, and surface spills,
