Pressure was rising Friday as BP continued testing its breached Gulf of Mexico well with no evidence so far that other leaks exist, said BP's Senior Vice President Kent Wells.
Wells said pressure was up to 6,700 psi (pounds per square inch) inside the well's capping stack. BP was looking for an optimal 8,000 psi, which would indicate that no oil was being forced out through a leak and that the well was undamaged and able to withstand the pressure of the cap.
The "well integrity test" began Thursday after two days of delays, first as government scientists scrutinized testing procedures and then as BP replaced a leaking piece of equipment known as a choke line.
