CBM operator rallies against blowout prevention measure

Upset about pending new “blowout prevention” requirements in the coal-bed methane gas industry, Powder River Basin operator Yates Petroleum has organized several public meetings on April 14 in Gillette to make its case against the measure.

Yates Petroleum declined to talk about its objections. However, the notice the company circulated this week claims “The Bureau of Land Management is considering an unneeded, undesirable and potentially unsafe change in drilling requirements that has strong potential to further delay drilling and reduce the number of Coalbed Methane wells drilled in the Powder River Basin.”

Late Wednesday afternoon, Wyoming BLM High Plains District manager Stephanie Connolly told WyoFile that the agency has been working quietly behind the scenes with the industry to resolve a concern about the potential to encounter pressurized gas while drilling for coal-bed methane in the Powder River Basin.

Connolly explained that when the industry began in earnest more than 10 years ago, operators drilled into relatively shallow coals which were not typically highly-pressurized with gas. However, as the play has advanced westward and into deeper coals, federal regulators are increasingly concerned about the potential for a “blowout” during the drilling operation.

Wyoming BLM officials are considering the implementation of “Onshore Order No. 2” which requires blowout prevention devices be used in the drilling operation. However, Connolly said details of the 20-year-old Onshore Order No. 2 are not easily applied to coal-bed methane gas drilling in the Powder River Basin. She said Wyoming BLM has been working closely with industry recently to figure out how to meet “the spirit of Onshore Order No. 2” while still taking into consideration the unique aspects of the Powder River Basin industry.

Connolly said BLM officials plan to continue working with the industry to resolve concerns, including a scheduled meeting with the Petroleum Association of Wyoming on Thursday.

There were a handful of “blowout” events in the coal-bed methane gas industry when commercial drilling first took off in the late 1990s, including one that resulted in a fatality. At that time, state and federal regulators worked with the industry to implement a blowout prevention requirement that involved a “bluey line,” which consists of a long pipe to vent unexpected belches of gas away from the rig crew.

This is not the first time Yates has organized public meetings due to concerns about regulations. About a year ago Yates called a similar public meeting to make its case that the BLM was unnecessarily holding up drilling permits.

WyoFile's goal is to provide readers with information and ideas that foster constructive conversations about the issues and opportunities our communities face. One small piece of how we do that is by offering a space below each story for readers to share perspectives, experiences and insights. For this to work, we need your help.

What we're looking for:

Your real name — first and last.
Direct responses to the article. Tell us how your experience relates to the story.
The truth. Share factual information that adds context to the reporting.
Thoughtful answers to questions raised by the reporting or other commenters.
Tips that could advance our reporting on the topic.
No more than three comments per story, including replies.

What we block from our comments section, when we see it:

Pseudonyms. WyoFile stands behind everything we publish, and we expect commenters to do the same by using their real name.
Comments that are not directly relevant to the article.
Demonstrably false claims, what-about-isms, references to debunked lines of rhetoric, professional political talking points or links to sites trafficking in misinformation.
Personal attacks, profanity, discriminatory language or threats.
Arguments with other commenters.

Other important things to know:

Appearing in WyoFile’s comments section is a privilege, not a right or entitlement.
We’re a small team and our first priority is reporting. Depending on what’s going on, comments may be moderated 24 to 48 hours from when they’re submitted — or even later. If you comment in the evening or on the weekend, please be patient. We’ll get to it when we’re back in the office.
We’re not interested in managing squeaky wheels, and even if we wanted to, we don't have time to address every single commenter’s grievance.
Try as we might, we will make mistakes. We’ll fail to catch aliases, mistakenly allow folks to exceed the comment limit and occasionally miss false statements. If that’s going to upset you, it’s probably best to just stick with our journalism and avoid the comments section.
We don’t mediate disputes between commenters. If you have concerns about another commenter, please don’t bring them to us.

The bottom line:

If you repeatedly push the boundaries, make unreasonable demands, get caught lying or generally cause trouble, we will stop approving your comments — maybe forever. Such moderation decisions are not negotiable or subject to explanation. If civil and constructive conversation is not your goal, then our comments section is not for you.
