What is Kick Intensity?
Kick intensity in drilling refers to the degree of underbalance in the wellbore, which occurs when the pressure exerted by the drilling fluid is lower than the pressure exerted by the formation fluids. The greater the difference between the pressure in the wellbore (due to the mud weight) and the formation pressure, the more intense the kick. The intensity of the kick impacts the speed and volume of the influx of formation fluids into the wellbore, which can be critical for the well’s safety.
In practical terms, kick intensity is related to how much the formation pressure exceeds the pressure exerted by the drilling fluid, and this imbalance is directly tied to the risk of a blowout. The pressure difference is typically measured in terms of pounds per gallon (ppg) or kilograms per cubic meter (kg/m³) for mud weight, or in pounds per square inch (psi) or kilopascals (kPa) for pressure measurements.
