On November 16, 2017, the Air Quality Control Commission directed the APCD to initiate and lead an oil and gas statewide hydrocarbon emissions stakeholder process in 2018-2019. The Commission directed that topics for evaluation, may include, but are not limited to:

  • the frequency of leak inspections
  • emissions from pipeline compressor stations
  • natural gas-driven and zero emission pneumatic controllers
  • potential expansion of the requirements adopted for the Denver Metro/North Front Range ozone area

The Division’s goal is to consider and recommend ways to reduce hydrocarbon emissions from statewide oil and gas operations. Representatives from local government, industry, environmental organizations and the Air Pollution Control Division are evaluating potential emission reduction strategies and are seeking public input.

These two FLIR videos were filmed at two existing Ursa well pads in Battlement Mesa on May 5, 2017.

Ursa B&V Lease, Battlement Mesa, CO
Filmed 5/5/2017
Ursa Operating B&V Lease Battlement Mesa, Garfield County, CO (39.450817, -108.048717)

This well pad is located between I-70 and the Colorado River. In this video you see a drilling rig surrounded by a sound wall. Notice the volume of emissions during drilling operations.

Ursa BMC Lease, Battlement Mesa, CO
Filmed 5/5/17
Ursa Operating BMC Lease Battlement Mesa, Garfield County, CO

This well pad is located on the south side of the Colorado River close to dozens of homes. Again in this video you see a drilling rig surrounded by a sound wall. Notice the volume of emissions during drilling operations.

All videos were filmed by a certified thermographer with an industry standard optical gas imaging camera, the FLIR GasFinder 320. The $100,000 camera is specially calibrated to detect methane and other VOCs, and is used by industry and regulators for that purpose.

Independent laboratory (third party) testing confirms that the FLIR Gasfinder Model GF 320 camera can see the following gases at the minimum detected leak rate (MDLR):

1-Pentene – 5.6g/hr
Benzene – 3.5g/hr
Butane -0.4g/hr
Ethane – 0.6g/hr
Ethanol – 0.7g/hr
Ethylbenzene – 1.5g/hr
Ethylene – 4.4g/hr
Heptane – 1.8g/hr
Hexane – 1.7g/hr
Isoprene – 8.1g/hr
MEK – 3.5g/hr
Methane – 0.8g/hr
Methanol – 3.8g/hr
MIBK – 2.1g/hr
Octane – 1.2g/hr
Pentane – 3.0g/hr
Propane – 0.4g/hr
Propylene – 2.9g/hr
SF6 (Sulfur Hexaflouride) – 0.026g/hr
Toluene – 3.8g/hr
Xylene – 1.9g/hr
