“…It must be stressed that firstorder reactions plot as straight lines on plots such as figure 2, whereas higher ordered reactions do not. The experiments referenced directly above lead to the conclusion that the effect of geologic time on organic-matter metamorphism may be overestimated, and ample geologic evidence supports this possibility (Price, 1983;Quigley and MacKenzie, 1988;Barker, 1991). As discussed in Price (1983), the original evidence (Karweil, 1956;Lopatin, 1971;Connan, 1974) for the hypothesis of geologic time being a controlling parameter in organic-matter metamorphism was obtained from geologically older sedimentary basins.…”

“…Thus, it was concluded that the same extent of organic-matter metamorphism would take place over long geologic times at low burial temperatures as would take place in short geologic times at higher burial temperatures. As discussed in Price (1983), however, in all the basins studied by Karweil, Lopatin, and Connan, there is compelling geologic evidence, apparently not originally observed, that suggests high to extreme paleo-heat flow existed in these basins, heat flows that later decayed to the low, present-day values. Thus, the original data base for the hypothesis of geologic time as a controlling parameter in organic-matter metamorphism was flawed.…”

“…Increasing burial temperature indeed probably is the principal drive for organic-matter metamorphic reactions; however, organic-matter metamorphic experiments carried out in closed, pressurized, water-wet systems that are thought to simulate nature are not first-order reactions but are higher ordered reactions (Rogers and others, 1962;Bostick, 1970 Rigby, 1973; Goodarzi and Murchison, 1977;Ishwatari and others, 1977;Chung and Sackett, 1978;Pearson, 1981;Price, 1983Price, , 1985 ( fig. 2).…”

“…In the absence of erosion, regardless of time-temperature burial history considerations, vitrinite-reflectance profiles should have surface intercepts of R 0 =0.25-0.29 percent. Whether one uses the vitrinite-reflectance paleothermometer of Price (1983) or of Barker and Pawlewicz (1986), surface intercepts of 0. 7±0.1 percent imply decreases in sediment burial temperatures of at least 100°C.…”

The Danzhai gold-mercury deposit is situated in the eastern region of Guizhou province, southwest of P. R. China.The Danzhai deposit is one of the gold-mercury-antimony-barite deposits in the Sandou-Danzhai ore belt, which is controlled by regional fault system Fi. The host rocks are Upper Cambrian and Lower Ordovician carbonates. Wall rock alteration is dominated by silicification and carbonatization. The major mineral assemblages consist of cinnabar, arsenopyrite, stibnite, pyrite and realgar, orpiment as well as barite. Chemical analyses show that gold is positively correlated with arsenic so that the gold may be mainly associated with arsenic minerals. The Au/Ag ratio is always greater than 1 in the gold ore. Hydrocarbons, particularly bitumen, are abundant in both the host rocks and the ore. The geological characteristics of the Danzhai gold-mercury deposit is quite similar to that of Carlin gold deposit in the western U.S.A except the Danzhai deposit is rich in organic matter and not associated with igneous rocks.A number of gold-mercury-antimony-barite deposits are distributed in or around the Majiang-Danzhai oil trap, and all of these deposits are present under the ancient interface between petroleum and oilfield brine (-500 m). Field observation shows that a variety of forms of hydrocarbon occur not only in the host carbonates but in the ore deposit as well. Patch-like bitumen, veinlet bitumen as well as stylolite-like bitumen host sulfide minerals such as arsenopyrite and cinnabar while metal sulfides such as cinnabar and gangue minerals also host bitumen. Besides bitumen, paraffin wax is also found in the deposit. An organic petrography study demonstrates that the bitumen in the minerals from the deposit is identical to the bitumen in the former Majiang-Danzhai oil trap. The bitumen is actually pyrobitumen, with a high reflectance, a mosaic texture, and an anisotropic nature but without fluorescence. The reflectance of bitumen from the deposit is high, varying from 2 to 3.8%, and the temperature calculated from this reflectance ranges from 150 to 210°C, indicating that the petroleum in the Majiang-Danzhai oil trap reached the thermal natural gas stage.

This chapter gives the reader a practical introduction into microbial enhanced oil recovery (MEOR) including the microbial production of natural gas from oil. Decision makers who consider the use of one of these technologies are provided with the required scientific background as well as with practical advice for upgrading an existing laboratory in order to conduct microbiological experiments. We believe that the conversion of residual oil into natural gas (methane) and the in situ production of biosurfactants are the most promising approaches for MEOR and therefore focus on these topics. Moreover, we give an introduction to the microbiology of oilfields and demonstrate that in situ microorganisms as well as injected cultures can help displace unrecoverable oil in place (OIP). After an initial research phase, the enhanced oil recovery (EOR) manager must decide whether MEOR would be economical. MEOR generally improves oil production but the increment may not justify the investment. Therefore, we provide a brief economical assessment at the end of this chapter. We describe the necessary state-of-the-art scientific equipment to guide EOR managers towards an appropriate MEOR strategy. Because it is inevitable to characterize the microbial community of an oilfield that should be treated using MEOR techniques, we describe three complementary start-up approaches. These are: (i) culturing methods, (ii) the characterization of microbial communities and possible bio-geochemical pathways by using molecular biology methods, and (iii) interfacial tension measurements. In conclusion, we hope that this chapter will facilitate a decision on whether to launch MEOR activities. We also provide an update on relevant literature for experienced MEOR researchers and oilfield operators. Microbiologists will learn about basic principles of interface physics needed to study the impact of microorganisms living on oil droplets. Last but not least, students and technicians trying to understand processes in oilfields and the techniques to examine them will, we hope, find a valuable source of information in this review.
