There is a near-ambient pressure test being conducted on the well to continually measure the pressure in the blowout preventer and the capping stack as responders prepare for the final stages of the relief well. Sensors measure the pressure in the well bore above the cement plug, as monitored at the capping stack. The differential drop in pressure on the morning of Aug. 14 was planned and expected – necessary for a scientific testing subset as part of the ongoing pressure tests.
BP plans and expects an increase in the ambient pressure of the well head to climb to approximately ~ 2500 psi this afternoon (Aug 17).
If you have questions, please contact the BP representative at the UAC Joint Information Center: (713) 323-1670.
