Earthquake swarms have made Oklahoma the earthquake capital of the United States.
A massive increase in wastewater injection disposal has followed a boom in horizontally drilled oil wells. Injected wastewater volumes are now suspected to contribute to seismic activity.
Oklahoma’s OCC, which oversees the oil and gas industry, has already moved to limit many disposal wells’ capacities and depths. As a result, more wastewater has to be trucked longer distances at higher costs and with wasteful consumption of fuel.
Disposal costs in this region are rapidly rising.
