Texas regulators warn of toxic wastewater leaks in Permian Basin

 

Oil and gas operators in the Permian Basin of west Texas got a warning this week from the Railroad Commission of Texas about growing underground pressure caused by wastewater disposal wells in the region. And it’s impacting some Oklahoma operators in the Basin.

Regulators went so far as to suggest the toxic wastewater from the shale drilling threatens to contaminate oil wells in the Basin. It’s become enough of a problem that Coterra Energy, a known operator in Oklahoma’s drilling plays, warned investors recently that they should not expect oil production this year from wells contaminated by wastewater leaks.

The Railroad Commission reportedly sent notices to water management operator NGL Energy Partners, a Tulsa-based firm, to warn about the pressure concerns. Other alerts or warnings were issued to Coterra Energy, Chevron, BP and water management operator Waterbridge Operating.

It’s not a new issue and Oklahoma City-based Devon Energy is one company well aware of it after it was sued by New Mexico producer Stateline Operating Co. and accused of causing toxic water leaks from disposal wells into production zones, rendering the reserves worthless.

Seeking Alpha reported Crescent Energy (CRGY) had argued in a November filing that four disposal wells proposed by Aris Water Solutions (ARIS) could leak dirty water into its production zone and “create mass degradation” of its oil and gas resources nearby; last week, Aris said it would not move forward with the four wells.
