Bourakébougou, Mali, to drill for water, but had given up on one dry borehole at a depth of 108 meters. “Meanwhile, wind was coming out of the hole,” Konaré told Denis Brière, a petrophysicist and vice president at Chapman Petroleum Engineering, in 2012. When one driller peered into the hole while smoking a cigarette, the wind exploded in his face.

“He didn’t die, but he was burned,” Konaré continued. “And now we had a huge fire. The color of the fire in daytime was like blue sparkling water and did not have black smoke pollution. The color of the fire at night was like shining gold, and all over the fields we could see each other in the light. … We were very afraid that our village would be destroyed.”

It took the crew weeks to snuff out the fire and cap the well. And there it sat, shunned by the villagers, until 2007. That was when Aliou Diallo, a wealthy Malian businessman, politician, and chair of Petroma, an oil and gas company, acquired the rights to prospect in the region surrounding Bourakébougou. “We have a saying that human beings are made of dirt, but the devil is made of fire,” Diallo says. “It was a cursed place. I said, ‘Well, cursed places, I like to turn them into places of blessing.’”
