Class II wells

Through the early years of the Shale Era, produced water gathering systems in the Permian were mostly small, simple and focused solely on transporting the salty, petroleum- and mineral-tainted water emerging from wells to nearby saltwater disposal wells. In the 2020s, though, these systems — now mostly owned and operated by third-party produced water specialists — have been becoming larger, more interconnected, and more likely to include at least some water recycling and reuse. In today’s RBN blog, we’ll continue our look at big, far-reaching produced water systems in West Texas and southeastern New Mexico. 

There’s a lot going on in the Permian produced water space lately. Crude-oil-focused production in the prolific shale play is generating vast and increasing volumes of produced water that needs to be recycled or injected into disposal wells. State regulators, concerned about injection-related seismic activity, are tightening their rules, ramping up oversight and cracking down. Produced water gathering systems are being expanded and long-distance pipelines are being planned and built. In today’s RBN blog, we discuss the latest developments and where things are heading.

Crude-oil-focused wells in the Permian generate massive volumes of produced water, and E&Ps have made tremendous strides in dealing with it. Most important, a growing share of that water is being recycled for use in new well completions. But challenges remain. Deep disposal wells — a popular option for handling produced water — can spur seismic events, and shallow disposal wells can do the same and also negatively impact oil well integrity. As we discuss in today’s RBN blog, Permian E&Ps are taking an increasingly comprehensive, holistic approach to produced water management. 

Admittedly, the idea of capturing carbon dioxide, cooling and compressing it into a weird, neither-liquid-nor-gas state, and pumping it deep underground for permanent storage would have baffled the crude oil wildcatters and pipeline builders that created the modern energy industry back in the 1940s and ’50s. They’d surely say, “You’re proposin’ to do what?!” But times have changed. The oil and gas business is entering an extraordinary era of transition, and producers, midstreamers, and refineries alike need to keep abreast of what’s happening regarding carbon capture and sequestration (CCS), how it will affect them, and — ideally — figure out ways to profit from it. That’s the impetus behind today’s RBN blog, in which we begin a deep dive into efforts to reduce emissions of man-made CO2 by capturing it from industrial sources and piping it to specially designed wells for permanent storage.
