Document Summary
Lecture 6 - physical and chemical properties pt 2. Carbon dioxide often a minor accessory, also associated with n and he. Common in areas of extensive volcanic activity, e. g. cordilleran chain of n. america. Carbon dioxide also a natural product of thermal maturation of kerogen. And given off during fermentation of organic matter, and oxidation of mature organic matter (oxidizing fluids or bacterial action). Methane in presence of oxygenated water can yield co2 and h2o. Has limited economic value (e. g. dry ice, use in enhancing oil recovery). But a greenhouse gas, so economically negative value. Co2 (9%) from sleipner west (m. jurassic gas + condensate field) injected into pliocene aquifer of. Utsira fm (above paleocene gas + condensate field of sleipner east). World"s first co2 sequestration project at sleipner field (norwegian sector, northern n. sea). Co2 (9%) from sleipner west (m. jurassic gas. Paleocene gas + condensate field of sleipner east).
