The hydrofracking that has opened up America’s enormous natural gas resources is a marvel of modern technology, but keeping gas and flowback water from those wells from seeping into drinking water depends on a far more mundane science: cementing.
Cementing is used to seal well bores on- and off-shore, in all types of oil and gas wells, and integrity standards are well established. But those standards “are often difficult to attain,” said James Saiers, a professor of hydrology at Yale University, speaking at a Resources for the Future (RFF) forum on “Managing the Risks of Shale Gas.” Keep reading →
