Natural Gas Terminology: Reservoir: Porous & permeable underground formation containing an individual bank of H.C.s confined by impermeable rock or water barriers characterized by a single natural pressure system. Field: Area of one or more reservoirs related to same structural feature. Pool: Contains one or more reservoirs in isolated structures. Wells can be classified as gas […]
Basically all formations penetrated during drilling are porous and permeable to some degree. Fluids contained in pore spaces are under pressure that is overbalanced by the drilling fluid pressure in the well bore. The borehole pressure is equal to the hydrostatic pressure plus the friction pressure loss in the annulus. If for some reason the […]
