This RPSEA Study appears that it will be useful. If IPANM Member companies are interested in participating, they could contact RPSEA.
The Research Partnership to Secure Energy for America (RPSEA) is initiating a joint industry project with US oil and gas industry partners to conduct and manage a real-world survey that will determine the precise levels of methane emitting from marginal wells in the United States.
RPSEA officials say the survey is needed to demonstrate whether the contribution of methane emissions from marginal oil and gas wells are much lower than what the Environmental Protection Agency (EPA) determined and used when it updated its New Source Performance Standards (NSPS) under former President Barack Obama.
As part of that rule, the EPA did not provide an expected exemption of marginal wells from Leak Detection and Repair (LDAR) requirements, RPSEA says, consequently adding a significant economic burden to oil and gas producers, particularly those which are independent or smaller.
The need to complete this research, RPSEA says, was brought to light after the US Court of Appeals for the DC Circuit this month ordered the EPA to lift a stay on the rule, reversing a Trump administration order to delay its implementation.
“The data that EPA used to develop this rule were assumptions, with limited accurate and defensible data from marginal wells [on which] to base this ruling,” said RPSEA President Tom Williams. “It is absolutely imperative that we provide EPA with data that shows the accurate methane emissions contributions made by marginal wells.”
The Independent Petroleum Association of America (IPAA) and US Oil and Gas Association (USOGA) support the proposed study, and RPSEA will be working with their members, plus state and regional associations and member companies of both organizations to conduct it. Work will commence when adequate funding is secured. Parties interested in participating or learning more can find more information on the study at the RPSEA website. http://www.rpsea.org/media/files/file/RPSEA%20Methane%20Study%20Press%20Release.%208-21-17.pdf
RPSEA says it has previously funded several projects on air emissions and is teaming up with Houston Advanced Research Center (HARC), GSI Environmental Inc. and advisory teams from academia, industry, and state and federal governments to perform this research, to ensure that there will be broad local presence and expertise in the various regions of the study.
Marginal oil wells are those with an average production of no more than 15 b/d, those producing heavy oil, or those wells producing not less than 95% water, with average production of not more than 25 b/d of oil. Marginal gas wells are those producing not more than 90 Mcf/d. There are more than 1.1 million oil and natural gas wells in the US, accounting for up to 20% of US oil production and about 13% of US natural gas production.
