LARAMIE, Wyo., June 27, 2018 /PRNewswire/ -- WellDog, Virginia Tech and Carbon GeoCycle announced today that they have collaborated to deliver the world's first successful direct verification of carbon dioxide sequestered in an underground rock.

弗吉尼亚理工大学和碳地球循环公司今天宣布，他们已经合作推出了世界上第一个成功直接验证地下岩石中封存的二氧化碳的方法。
The verification, made using WellDog's proprietary Reservoir Raman System, reveals that carbon dioxide injected over the last two years successfully flowed into all of the targeted coal seams. The US$15.5MM sequestration project is located in Buchanan County, Virginia. The project is funded by the US Department of Energy, Virginia Tech, and private industry.
使用WellDog专有的储层拉曼系统进行的验证表明，过去两年注入的二氧化碳成功地流入了所有目标煤层。 这个价值1550万美元的封存项目位于弗吉尼亚州的布坎南县。 该项目由美国能源部，弗吉尼亚理工大学和私营企业资助。
The test involves injecting over 13,000 tons of carbon dioxide into stacked unmineable coal seams at depths of 900 to 2,000 feet with the goal of storing carbon dioxide while simultaneously enhancing natural gas recovery.
该测试包括在深度为900至2,000英尺的堆积不可燃煤层中注入超过13,000吨二氧化碳，目的是储存二氧化碳，同时提高天然气的回收率。
"Carbon sequestration in geologic formations is our best way to slow and reverse climate change," said John M. Pope, Ph.D., chief executive officer of WellDog. "But understanding how, where and for how long sequestration occurs in rocks thousands of feet below ground is difficult."
“地质构造中的碳封存是减缓和逆转气候变化的最佳方式，”WellDog首席执行官John M. Pope博士说。 “但是，了解在地下数千英尺的岩石中发生封存的方式，地点和持续时间是很困难的。”
"In this project the carbon dioxide flowed into the wellbore, but until we took direct downhole measurements in each coal seam, significant uncertainty persisted regarding which coal seams the carbon dioxide had sequestered," explained Pope. "We are pleased that WellDog's technical services and Carbon GeoCycle's sequestration expertise were able to help Virginia Tech's experts confirm that all of the coal seams took up carbon dioxide. This result represents an important step for sequestration efforts worldwide."
“在这个项目中，二氧化碳流入井筒，但在我们对每个煤层进行直接井下测量之前，对于二氧化碳封存的煤层存在很大的不确定性，”Pope解释说。 “我们很高兴WellDog的技术服务和Carbon GeoCycle的封存专业知识能够帮助弗吉尼亚理工大学的专家证实所有的煤层都吸收了二氧化碳。这一结果代表了全球封存工作的重要一步。”
"Results from the test are very promising," said Nino Ripepi, Ph.D., associate professor of mining and minerals engineering at Virginia Tech and a manager of the project. "We have shown that coal seams can safely store carbon dioxide while at the same time enhancing gas. This is one of the first steps toward commercialization of these technologies."
“测试结果非常有希望，”弗吉尼亚理工大学采矿与矿物工程副教授，该项目经理Nino Ripepi博士说。 “我们已经证明，煤层可以安全地储存二氧化碳，同时增加天然气。这是实现这些技术商业化的第一步。”

Research partners in the project included Virginia Center for Coal and Energy Research, Virginia Tech; Virginia Department of Mines, Minerals and Energy; DOE's National Energy Technology Laboratory; Marshall Miller & Associates; Southern States Energy Board; CONSOL Energy; Geological Survey of Alabama; Sandia Technologies; Det Norske Veritas; WellDog; and Carbon GeoCycle.
The verification methods used by the partners included WellDog's unique downhole geochemical Reservoir Raman System, in which a full spectrum chemical analyzer and other sensors are lowered into a wellbore and used to identify directly and unambiguously the types and amounts of liquids and gases it contains. By watching those liquids and gases flow over time and at various depths, the system enabled direct confirmation of carbon dioxide flows into and out of rock formations.
The technology has been used extensively to address key downhole challenges including finding natural gas and other gases occurring naturally in underground formations (for example, see https://www.ogj.com/articles/print/volume-115/issue-1/drilling-production/shell-uses-raman-spectrometer-to-evaluate-marcellus-gas.html) and evaluating unintended byproducts of carbon dioxide injection in underground formations (for example, see http://anlecrd.com.au/wp-content/uploads/2016/08/7-0314-0229-Milestone-2_2-Report.pdf).
