Here is Bob Arrington’s* citizen review of the Mamm Creek Phase III Study:
It looks like [Dr. Geoffrey] Thyne is getting a chance for redemption. If I recall the earlier studies [Phase I & II], and they need to be copied before they disappear, Thyne pointed to the benzene in the mix of thermogenic and biogenic as an indicator it came from the bowels. Remember all the sparging they did to cut the benzene and all promoters were yahooing about cutting in half or less. My gut feeling is this is a industry wide concern, that they really screwed up, and they have put the best minds to obfuscate this area. Early in the game, COGCC knew was bad and then [former COGCC executive director Dave] Neslin took the show to Washington. Shortly thereafter, he took his early out through the state revolving door. [Dave Neslin is currently a partner at Davis Graham & Stubbs, the firm that represents Encana.]
The chloride now coming up also indicates deep stuff is coming up.
Now, if I were in an industry that wanted to perpetuate a story that fracking could never contaminate ground water, and my operation did contaminate the ground water, how could I create a lot of biogenic methane to “mask” the thermogenic methane?
The question would still be: “What about the benzene?”
And I (the industry) would say: “It appears that occurred naturally, too.”
Then all it would take is some sparging with CO2 and a little addition of microbes and pay someone to discover it. Of course, it might take a little extra time for it all to cook to the right proportions …

INTRODUCTION [emphasis added]
Carbon sequestration is one of three major pathways to achieve stabilization of greenhouse gas concentrations. Compared to the other two pathways—improving the efficiency of energy use and reducing the carbon content of fuels—carbon sequestration is the newest approach and is less mature from a research and development perspective. In fact, it is a new field of science and technology, one in which there is a great opportunity for the identification and exploration of novel concepts. This paper explores some of these opportunities, identifies several current avenues for novel concepts, and focuses on one “value-added” concept.
Novel approaches to carbon sequestration can play an extremely important role in extending the boundaries of technology options for CO2 capture, storage, and reuse. Opportunities include conversion to benign, stable compounds for long-term storage or to value-added products for reuse. For example, one area is CO2 mineralization. One concept uses carbonic anhydrase enzyme to convert dilute, unseparated CO2 to HCO3 – and then to everlasting calcium and magnesium carbonates. This could offer a stable, essentially permanent storage option for carbon sequestration. Another area is biogenic methane. One concept is the geologic storage of CO2 in depleting and depleted oil and gas reservoirs, with subsequent conversion of the CO2 to CH4 via designer microbes or biomimetic systems that operate either below or above ground. This could lead to “closed-loop” fossil systems, providing a sustainable methane economy with near-zero net CO2 emissions.
