Dating groundwater speed dating events in minnesota
Because of the long residence time for groundwater in the hydrologic cycle, the last few decades have seen expanding study of groundwater systems.
It is therefore important to continually refine our interpretation of hydrogeologic, geochemical and isotopic data to better understand the spatial and temporal movement of water in the subsurface.
C), was first produced artificially in 1940 by Martin Kamen and Sam Ruben, who bombarded graphite in a cyclotron at the Radiation Laboratory at Berkeley, CA, in an attempt to produce a radioactive isotope of carbon that could be used as a tracer in biological systems (Kamen (1963) ; Ruben and Kamen (1941) ).
Carbon-14 of cosmogenic origin was discovered in atmospheric CO in 1946 by Willard F.
In this study, we show how physical models describing hydrocarbon/groundwater interaction can be developed by the noble gases in the hydrocarbon phase and, based on these models, initial crustal radiogenic He age of the groundwater associated with each hydrocarbon reservoir to be derived.
We illustrate the strengths and weaknesses of this approach using data from case studies from the San Juan Basin coalbed methane gas field in New Mexico, USA, the Magnus oilfield in the UK North Sea and the Hugoton-Panhandle giant gas field that spans Kansas, Texas and Oklahoma, USA.
