REPORT SHOWS NATURAL GAS WELLS HAVE NO IMPACT ON LOCAL WATER SUPPLY
DENVER, CO - A well respected hydrogeological/engineering company
has found that four exploratory gas wells have not impacted Delta
County's water supply, according to a report prepared by Wright Water
Engineering.
Wright Water Engineering ("WWE"), based in Glenwood Springs and
Denver, found that Gunnison Energy Corporation's ("GEC") four natural
gas test wells did not endanger local drinking water during production.
All four wells were drilled to levels deeper than 2,400 feet, where the
isolated water has high salinity. There was no connection between the
upper potable waters and any lower saline waters, the report states. The new report entitled Initial Review of Water Quantity and
Quality: Data From Four GEC Gas Exploration Wells in Delta County
analyzes water samples and bore hole drillings from four natural gas
wells: Lone Pine #1, Stevens Gulch #1, Dever Creek #1 and Spaulding
Peak #1. "From the beginning of this long process, we said we would
share this information with the community, which includes nearly 300
employees of our parent company - Oxbow Corporation" said GEC Vice
President Tony Gale. "These results confirm what we said from the
beginning: there was no chance of the test wells impacting local water
supplies."
Among the key findings in the report are the following:
- The
local water supplies were protected from GEC's drilling and exploration
activities at Spaulding Peak, Dever Creek, Lone Pine and Stevens Gulch
by using multiple solid steel casing and cement as a physical barrier.
- GEC did not encounter potable surface water at depths
greater than approximately 800 feet. GEC encased each well in steel and
cement to a depth below the potable water-bearing intervals, removing
all risk of connection to any saline water encountered.
- Hydraulic fracturing data showed no connection between the
hydrofractures and shallow groundwater in any of the four wells, based
on hydraulic pressure plots obtained during stimulation.
- Each exploration well was drilled to an average depth of
2,400 feet or the depth of the Rollins Sandstone located below the coal
seams. Analyses performed on the water encountered at these levels
revealed that it was non-potable with average Total Dissolved Solids
values between 3,900 mg/L and 14,695 mg/L. (EPA secondary drinking
water standard is 500 mg/L).
Gale will present a copy of the most recent WWE report to Delta
County officials. A report can be downloaded from GEC's website at www.northforkvalleyproject.com.
GEC is part of the Oxbow Group of Companies. Based in West Palm
Beach, Florida, Oxbow owns and operates the Elk Creek Coal Mine in
Somerset, Colorado, and the Terror Creek Coal Loadout and Oxbow
Trucking Company in Paonia, Colorado. For more information contact:
