The company has voluntarily capped and abandoned all of its 1-inch flowlines on vertical wells in the Weld County area.
Colorado's top regulator says as long as the rules are followed, “there’s very little risk, very little potential harm of having empty, abandoned, plugged, capped lines in the subsurface.”
Cities along the Front Range are growing rapidly and the state’s 54,332 oil and gas wells aren't going anywhere.
Anadarko believes the wells are safe but is shutting them down because of the "special circumstances and sensitivity surrounding this equipment."
If a flowline isn’t regularly tested and properly abandoned, it can cause problems.

The deadly accident in April is leading to a discussion about whether houses should be built farther away from existing oil and gas wells.
Oil and gas operators must inspect existing oil and gas flowlines within 1,000 feet of occupied buildings within 30 days.
The state's oil and gas regulators are involved in the investigation because there was an active vertical well less than 200 feet from the home.
