As you stated, the incident in the Gulf of Mexico was tragic—eleven families were affected. We as an industry have taken that very seriously. Chevron, being active in the Gulf of Mexico, has gained a lot of valuable information and applied it worldwide to our operations, as we did in the Lona operation.
Some of the procedures now evolving as requirements in the Gulf of Mexico that we implemented in the Lona operation had to do with our blowout preventer—the testing of it and the protocol we use. Before we installed that piece of equipment, which is a critical piece for our secondary well control containment, we full-pressure-tested the electronics of the system on surface and at the wellhead, subsea. We tested our secondary systems that connect or operate the BOP with our acoustic system to ensure its integrity and operability. We tested our remote operating vehicle, which we could send subsurface. If those two systems fail, we can intervene and close the blowout preventer. We incorporated that into our protocol. We also have redundancy in our ROVs, our remote operating vehicles, so if one fails we have a backup.
