As for the second report, Halliburton sent it on April 18 to BP officials aboard the Deepwater Horizon as well as on land
. The April 18 report makes recommendations as noted by the Houston Chronicle to address flaws with the cement job "used to secure pipe-like casing to the walls of the Macondo well." Macondo is the official name of the oil and gas prospect being drilled by the Deepwater Horizon. Sepulvado however could not corroborate the existence of this report as he could the April 15 report. Regardless of this fact, there is more than enough evidence to indicate negligence on the part of BP. The presence of three reports, the corroboration of at least one, and the testimony given by Sepulvado, easily give even more weight to the many lawsuits against BP.
