With the prospect of about a dozen potential ballot proposals aimed at the oil and gas industry on Colorado’s November ballot,Anadarko Petroleum Corp. on Monday showed off its efforts to reduce and avoid environmental damage in its drilling, fracking and production operations in northern Colorado.
Anadarko (NYSE: APC), based in the Houston area, expects to invest nearly $2 billion in is Colorado operations this year. The company employs more than 1,500 people in the state.
The efforts include:
- Drilling multiple wells about 30 feet apart on a single well pad, reducing the amount of ground needed to drill oil and gas wells.
- Drilling horizontal wells that can stretch up to two miles underground to take the place of many wells needed to produce the same amount of oil.
- Using closed loop, or “pitless,” drilling operations to eliminate the lined, but open, pits of water and mud that come from drilling the well.
- Concentrating the company’s hydraulic fracturing operations in a single location, called a Stim Center, to handle frack jobs on wells up to nearly a mile away, reducing the amount of truck traffic on roads, as well as the time and money spent setting up fracking operations at individual well pads, then moving to the next pad. (Hydraulic fracturing uses water, sand and chemicals to crack underground rock formations to allow oil and natural gas trapped in the rock formation to flow into an oil and gas well.)
