...That's because mud isn't the only thing boiling over in Porong. Villagers displaced by the eruption blame the disaster on PT Lapindo Brantas, an Indonesian mining company drilling for natural gas in the area. Lapindo is partly controlled by the family of Aburizal Bakrie, Coordinating Minister for the People's Welfare, one of Indonesia's wealthiest men and an ally of President Susilo Bambang Yudhoyono. Victims of the disaster say that a murky web of political influence and corporate fecklessness has blunted the official response to the mud eruption. "Everyone is suspicious," says Mas Achmad Santosa...
...Some independent geologists, including Davies, believe that Lapindo may have inadvertently roused the awesome force slumbering beneath Indonesia. "I'm 98% certain this was due to drilling," he says. Davies, who visited Porong last year and has studied the eruption extensively, thinks he knows how that happened. On May 27, Lapindo's Banjar Panji-1 well was operating in a field not far from Ahmad Mudakir's village. The well's target was a shelf of limestone some 9,800 ft. (3,000 m) below the surface. Lapindo's drillers were searching for natural-gas deposits, but the well...
...Such a drop, called a loss of circulation, isn't uncommon in gas drilling. It usually means that natural fractures inside the borehole are allowing drilling fluid to leak out. Lapindo's engineers responded by pumping heavy drilling mud into the well to seal the cracks and restore pressure. Then they began to pull out the drill. Davies thinks that while they were removing the drill on the morning of May 28, they set off a massive "kick," in which high-pressure water and gas from the surrounding rock flowed into, rather than out of, the borehole. To prevent...
...when drilling in geologically unstable areas, engineers install steel casing at greater depths, where the low density of the rock might allow fluid to escape from the borehole. In the event of a kick, the casing allows drillers to maintain the integrity of the well. Swarbrick, who has reviewed Lapindo's drilling plan, says the company originally intended to install casing at depths of 3,500 ft., 4,500 ft. and 8,500 ft. (1,000 m, 1,400 m and 2,600 m). "The conventional well design in that sort of pressure environment would be to install casing," Swarbrick...
...Thus far, the soap opera hasn't been enough to dispel that worry, or polish Lapindo's befouled image. But with the mud still erupting at a rate of 120,000 cu m per day and all efforts to stanch the flow failing, there may be plenty of time for a sequel...
