Why Do Oil Wells Gush?

What causes an oil well blowout?

A very common cause of oil blowouts is rock formation pressures around an oil reservoir.

Oil well companies counter the pressure by using mud at the drilling site.

If the pressure balance isn’t managed properly, oil, gas, and water can infiltrate the wellbore or even the drill itself.

A blowout can then result..

What causes pressure in an oil well?

Formation pressure is a result of the hydrostatic pressure of the formation fluids, above the depth of interest, together with pressure trapped in the formation. Under formation pressure, there are 3 levels: normally pressured formation, abnormal formation pressure, or subnormal formation pressure.

What is the difference between a kick and a blowout?

A kick is defined as flow of formation fluids or gas into the welbore, a blowout is the uncontrolled release of the fluid or gas, gained through the kick. A blowout can take place at the surface or into another formation( underground blowout).

How dangerous is oil rigging?

OFFSHORE oil rig construction workers are being paid allowances of up to $90 a day because their cabins lack private showers and toilets. And resources companies have warned that a wages explosion risks putting the brakes on the nation’s minerals boom.
