According to a representative from the Colorado Oil and Gas Association speaking to channel 9 news, every well in each flooded county was being monitored several times a day and that there have been no "significant" leaks and they have so many crews on hand they're actually helping with other rescue efforts because they're not needed for spills from wells.

The representative also said multiple times that if you spot a oil or gas leak, that what she needs is not just photos, but locations for where the photos are so they can go try and deal with any problems found.

"With the Texas gulf coast, they know in advance a hurricane is coming," said Irene Fortune, a retired chemist who worked for British Petroleum and is now running Loveland City Council.

"To have something this inland, this level of flooding in an area with high oil and gas development, it's new territory," Fortune said.

Gary Wockner, executive director of Save Our Colorado, said, "Every flooded well needs to get inspected."

"The COGCC needs to pass new regulations for drilling in floodplains to better protect people and the environment," Wockner said.

"The actual wells are meant to hold pressure on the inside. They're designed to be fluid tight," William Fleckenstein, a professor of petroleum engineering at the Colorado School of Mines said.

Concern arises when the tanks are knocked over or damaged, Fleckstein said.

The "worst case scenario," however would damage to a high pressure gas line, which would leak hydrocarbons in the air and be "very explosive," Fleckenstein said.
