oil and gas

the passage of oil depends on the viscosity of the fluid and the permeability of the porous stratum but most importantly on driving pressure. this can be due surface gas, as in gas- cap reservoir, or to water as in water –drive reservoir. at the surface gas often comes out of solution in the oil and helps to lift the oil by expansion. this is often enhanced by passing gas down between the tubing and casing to promote the «air-lift» effect.

the production from each well paces to a central gathering station where gas is separated and solids are removed by either setting or centrifuging . the gas separation is purely mechanical at this stage. the separated crude oil and gas are now ready for further processing.

wells often must be treated to improve the recovery from a reservoir , or to remove barriers within the producing formation which prevent easy passage of the fluid into the well-bore. such processes are knows as well-stimulation treatmen​
