Anadarko Petroleum wants a fleet of at least six vehicles with armor heavy enough to stop AK-47 bullets at its natural-gas project in Mozambique. And it needs them soon. Anadarko Petroleum said late on 30 June that it has tested more than 4,000 active oil and gas lines and plugged another 2,400 inactive ones per a state order issued after a fatal home explosion in Firestone, Colorado, in April. Two months after a Colorado home exploded near an Anadarko well, the reverberations are still rattling the oil industry, driving down driller shares and raising fears of a regulatory backlash. The company that owns a gas well linked to a fatal home explosion in Colorado says it will permanently shut down that well and two others in the neighborhood.
