Why does oil gush out of the ground?
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.
How does oil shoot out of the ground?
Oil and gas can get trapped in pockets underground such as where the rocks are folded into an umbrella shape. Oil and gas can move through the porous rocks (rocks with gaps between the grains). The oil and gas move upwards from the source rock where they were formed.
