Hydraulic fracturing is a treatment performed on oil and gas wells, most commonly used on productive zones exhibiting low to moderate permeability. Special viscosified oil or water based fluids are pumped into the reservoir at high pressure and rate, causing fractures radiating out from the casing.
Nitrogen Pumping operation
Nitrogen gas is routinely used in the oilfield industry, primarily to unload the well-bore of solids and fluids which otherwise restrict production, due to the hydrostatic effect of the well-bore material. Nitrogen gas is an integral part of well-bore cleaning with Coiled Tubing Units.
