Halliburton, in a statement released late last night, downplayed the significance of cement testing results released publicly yesterday by the national oil
“„Contrary to the letter, however, the slurry tested in February was not “a very similar foam slurry design to the one actually pumped at the Macondo well.” … Additionally, there are a number of significant differences in testing parameters, including depth, pressure, temperature and additive changes, between Halliburton’s February tests and two subsequent tests Halliburton conducted in April. Halliburton believes the first test conducted in April is irrelevant because the laboratory did not use the correct amount of cement blend.
“„Halliburton believes that had BP conducted a cement bond log test, or had BP and others properly interpreted a negative-pressure test, these tests would have revealed any problems with Halliburton’s cement. A cement bond log test is the only means available to evaluate the integrity of the cement bond. BP, as the well owner and operator, decided not to run a cement bond log test even though the appropriate personnel and equipment were on the rig and available to run that test. BP personnel have publicly testified they intended to conduct the cement bond log test at a later date and to perform any necessary remedial work at that time.
