Hydraulic fracturing is used to improve the recovery of oil and natural gas by forcing water and specialized chemicals into the rock formation at extremely high pressures to a.) create or expand cracks (fractures) in the formation and b.) push proppant into those fractures to keep them open, which allows oil and natural gas to flow into the well more easily.
Cementing services are used when drilling new wells, reworking of existing wells, and plugging wells at the end of their lives. Cemented casings provide support to the wellbore and provides zonal isolation, preventing the flow of fluids between geological formations and isolating groundwater from contamination.
