“…Previous studies demonstrate the strong microscopic heterogeneity of Chang 6 3 reservoir sand body in Huaqing oilfield, which leads to prominent Jamin effect in the late water flooding, difficult development process, low productivity, and massive residual oil, thereby significantly restricting the effective development of Huaqing oilfield Ren et al 2015;Zhang et al 2015a, b). The water flooding efficiency is found to be closely related to the microscopic pore structure of the reservoir, which has not been sufficiently addressed in the previous studies (Zhao et al 2012). Moreover, fluid flow and migration in the reservoir pore space can be intuitively observed in the water flooding experiment in the microscopic real sandstone model under the microscope, which can help analyze the rule of water flooding and the controlling factors of water flooding efficiency in conditions with different types of microscopic pore structures (Bai et al 2016;Halim et al 2015).…”

Chang 6 3 reservoir in Huaqing oilfield, Ordos Basin, China is featured by strong pore structure heterogeneity, which leads to prominent Jamin effect in the water flooding, difficult development process, low productivity, and massive residual oil. Accordingly, this study aims to explore the microscopic pore structure of Chang 6 3 reservoir and investigate its influence on the water flooding efficiency, based on a series of comprehensive analyses, including physical property analysis, casting thin section observation, scanning electron microscopy measurement, high-pressure mercury injection, constant rate mercury injection, and microscopic real sandstone water flooding model. It is demonstrated that gray and gray-brown feldspathic sandstone are the main reservoir lithology in the study area, with dominant pore types of residual intergranular pores and feldspar dissolution pores. Pore throat radius is unevenly distributed, and small and micro pores take the majority. Based on the comparison of capillary pressure curve characteristics and comprehensive analysis of corresponding parameters, the pore structure of the Chang 6 3 reservoir is divided into four types, namely types I-IV. They have different reservoir spaces, and their reservoir and seepage capacities decrease in the order of types I-IV pore structures. Moreover, displacement patterns in them are also different, with the finger-like-reticular displacement as the primary. In addition, pore throat radius and distribution play a critical role in the water flooding. It is also demonstrated that the water flooding efficiency increases with permeability and porosity, pore structure quality, and pore throat distribution evenness.

“…Apart from economic significance, such as enhanced oil recovery, microbial community of oil fields may serve as convenient objects for describing microorganisms of the deep biosphere, due to their accessibility via numerous wells. The variety of microorganisms in oil fields of differing geology and exploitation type has been characterised by cultivation and molecular techniques (Rosnes et al 1991;Stetter et al 1993;Voordouw et al 1996;Magot et al 2000;Orphan et al 2000;Bonch-Osmolovskaya et al 2003;Li et al 2006Li et al , 2007Agrawal and Lal, 2009;Gittel et al 2009;Ren et al 2011;Yamane et al 2011;Kobayashi et al 2012;Zhao et al 2012). However, the potential of high-throughput sequencing to improve our understanding of microbial diversity in oil strata is neglected by difficulties in isolation of sufficient DNA amount from crude oil.…”

The dominant microbial components of fluids from wells in pristine and water-injected, high-temperature, Western Siberian oil fields, were analyzed by PCR-DGGE. Particular emphasis was placed on sulphatereducing organisms, due to their ecological and industrial importance. Bacterial phylotypes obtained from the non-water-injected Stolbovoye oil field were more diverse than those from the Samotlor field, which is subject to secondary oil recovery by reinjection of recycled production water. The majority of phylotypes from both sites were related to Firmicutes. The low similarity to their closest relatives indicates unique bacterial communities in deep underground production waters and crude oil. Archaeal phylotypes detected only in the Samotlor samples were represented by Methanosarcinales and Methanobacteriales.Downloaded by [FU Berlin]

“…In a bacterial community, many different organisms will perform the same processes and probably be found in the same niches (Zhao et al, 2012). Factors that affect microbial diversity can be classified into two groups, i.e., abiotic factors and biotic factors.…”

“…Biotic factors include plasmids, phages, transposons that are types of accessory DNA that influence the genetic properties and in most cases, the phenotypes of their host and thus have a great influence on microbial diversity (Zhao et al, 2012). In addition, protozoans are also reported as influencing the microbial diversity (Clarholm, 1994).…”

Difficulties in cultivating most of the microorganisms limit our ability to study microbial ecosystems. Molecular methods are valuable tools for investigating the diversity and structure of bacterial communities. These techniques can be used on culturable as well as non-culturable bacteria. Cultivation independent techniques based on nucleic acids extracted from the environment provide information on community structure and diversity. Analyses of DNA can determine the numbers of different genomes. Ribosomal RNA (rRNA) or rDNA (genes coding for rRNA) fingerprinting, probing and sequencing can be used to detect and identify organisms. The combination of different methods that complement each other is a useful strategy for monitoring changes of microbial communities in natural ecosystems.
