Once the pressure test is finished and officials are confident the seal will hold permanently, the well will be declared dead.
74 barrels of cement pumped in Friday has dried.
Engineers will now exert 15-thousand pounds of pressure against the cement plug to make sure it won't budge.
The pressure test will happen around 11 o’clock Saturday night and will take about half an hour.
The test is the only way to ensure the well is dead.
