Colorado has one of the most stringent sets of rules in the country for testing groundwater in and around oil and gas drilling, but that doesn’t mean every question has been settled. That’s why we were pleased to hear details of a pilot program for real-time water-quality monitoring that will provide concerned citizens with more information than ever before. Colorado State University’s effort is being conducted with Noble Energy and several government agencies. It ultimately will have a website that will allow citizens to view the results.
DENVER — Colorado State University water engineers have come up with deep-well sensors, which are inserted in gas and oil wells to monitor any impact hydraulic fracturing may have on water quality. “We know 63 percent of the state’s 2,200 new gas and oil wells drilled in Colorado were drilled in Weld County, which is why we have ten test sites here,” said Dr. Ken Carlson with CSU. “The hope is to give realtime data to anyone with a computer, on any type of impact fracking might have in their community.”
A website that provides real-time information about water quality around oil and natural gas sites in the Denver-Julesburg Basin launched Wednesday, giving regulators, residents and others access to how water may be affected by energy operations. Colorado Water Watch, created by Colorado State University researchers, is a monitoring tool that collects groundwater quality data from oil and natural gas sites. The information then uploads every hour to the CSU-operated website.
A strategy of monitoring for easy to measure parameters can be effective detecting real-time, anomalous behavior relative to a pre-determined baseline.
A lot of people are watching how Colorado balances its history as a center of oil and gas production with the current push at the ballot box to make it harder for energy companies to operate in the state, according to former Gov. Bill Ritter.
Is there methane in Weld County’s water?A new study by CSU researchers indicates there is, but it’s not the same methane for which companies are drilling.
Conducted through Colorado State University in partnership with Noble Energy, the Colorado Water Watch demonstration project will soon begin water table monitoring in test wells at roughly 10 Noble production sites in a real-time look at how the water changes.
The project described in this report is the first step in addressing the concerns raised by reports by the State Review of Oil and Natural Gas Environmental Regulations, the Natural Gas Subcommittee of the Secretary of Energy’s Advisory Board and other studies. A framework is proposed to assess the lifecycle of water and energy resources of Noble Energy assets in the Wattenberg field. Data from Noble’s Wattenberg wells are used to assess the overall water use and average water intensity in the region as a first application of the general framework.
Two teams of researchers will soon begin testing water throughout Weld County to determine what effects or changes, if any, come from oil and gas industry activities. In the end, there may be no question left as to the industry’s effects on water. “I think people really are just concerned about their drinking water and, hopefully, will gain some confidence and reassurance by monitoring,” said Reagan Waskom, director of the Colorado Water Institute at CSU.
The objective of this study was to develop models that could be used to predict frac flowback and produced water volumes considering the unique decline rates that exist for different types of oil and gas wells.September 9, 2013 Category: CEWC Research, Fact Sheets

“I think people really are just concerned about their drinking water and, hopefully, will gain some confidence and reassurance by monitoring,” said Reagan Waskom, director of the Colorado Water Institute at CSU. “The message here is that there are several comprehensive efforts to determine whether or not we need to be worried about our drinking water.”
This Excel tool provides an rough prediction of water produced from Noble Energy Inc. wells in the Wattenberg Field in Northern Colorado. Protocols were developed for vertical and horizontal wells based on historical water production data, and by combining these two protocols the tool provides future water production prediction (with 2σ (95%) confidence interval) from input numbers of new wells in every year.
This study provides an extension of the research by Considine, et al. (2011a) with a more detailed analysis of notice of environmental violations (NOV) from the Pennsylvania Marcellus Shale industry. Not all environmental violations result in environmental pollution because many violations are citations for administrative failures or are issued to prevent pollution from occurring.
This study provides an analysis of the volume of water required for unconventional shale gas and shale oil development and how efficiently the water is used. A general material balance is used to assess the life cycle of water and energy resources of 445 Noble Energy Inc. wells in Wattenberg
field in northeastern Colorado. Water use data as well as oil and gas production data were collected from Noble Energy wells and separated by well type (horizontal or vertical) and water use (drilling and hydraulic fracturing).
Recently, COGA published Colorado oil and gas industry water usage facts, “Water Use Fast Facts”, which can be found at www.coga.org, under Fast Facts. In summary, the facts estimate water use for oil and gas development at 0.13% of Colorado’s total 2012 water use. That’s 6.5 billion gallons of water for the year at far less than one percent of all water use. These billions of gallons are compared with other users in the state and, despite being “billions” in number, they are the lowest of notable users, such as Irrigation (4497.5 billion gallons/year), Public Supply (315.4 billion gallons/year), and Mining (7.8 billion gallons/year). Also, the one-time use of 5 million gallons for one well are contrasted to water uses we can all relate to, like a Colorado coal-fired plant in one day or 30 Denver-area homes in one year.
