Recommended Best Practices
Minimizing Greenhouse Gas Emissions From Oil & Gas Operations
Leak Detection and Repair (LDAR) programs have become an important part of reducing air emissions by identifying equipment leaks from oil and gas production
equipment, such as tank battery thief hatches and vent valves, pipe connections, compressor seals, flanges, compression fittings and mechanical seals.
Successful LDAR programs provide scheduled routine surveillance and maintenance designed to identify and mitigate natural gas leaks early.
University Lands recommends conducting LDAR inspections and encourages inspection teams to review the air permit issued by the Texas Commission on Environmental
Quality (TCEQ) for each facility prior to conducting the LDAR inspections. Please note that pneumatic controllers with bleed rates of less than 6scf/hr are
currently exempt under subpart OOOOa of EPA’s emissions guidelines. Pneumatics controllers that do not meet the permissible OOOOa exemption limits should be
converted to instrument air or replaced with low bleed control devices.
University Lands encourages aerial flyover surveys using technology that can identify large air emission sources so that operators can more quickly detect and
mitigate the most problematic emissions sites.
Best emission management practices typically include the utilization of Vapor Recovery Units (VRU), Vapor Recovery Towers (VRT), Thermal Oxidizers and Flare Stacks
to manage emissions from oil, condensate and produced water storage tanks.
Operators are encouraged to purchase infrared (IR) cameras to improve emission inspection efforts across all assets on PUF Lands, regardless of facility age or
production volumes. University Lands also has an IR camera available for use at specified operator locations upon request. Contact:

University Lands supports the work of and recommends membership in The Environmental Partnership,
an operator-driven organization committed to voluntary emission reduction programs, transparent reporting and sharing of best practices, learnings and new technologies.
The University Lands’ Environmental Stewardship Incentive Program (ESIP)
is a cost-share opportunity for operating companies on PUF Lands. ESIP dollars are available for various types of initiatives focused on emission reductions,
facility upgrades, purchase and deployment of new technologies, and engagement in relevant research on PUF Lands.
University Lands routinely encourages operators to recomplete or plug abandoned marginally productive wells.
Operators are encouraged to participate in the Department of Energy’s study
to quantify methane emissions from marginal wells. University Lands welcomes test sites on PUF Lands.
