Microbial enhanced oil recovery (MEOR) is a technology that could potentially increase the tertiary recovery of oil from mature oil formations. However, the efficacy of this technology in fractional-wet systems is unknown, and the mechanisms involved in oil mobilization therefore need further investigation. Our MEOR strategy consists of the injection of ex situ produced metabolic byproducts pro...

in the present study, the potential of a bacterial consortium of enterobacter cloacae and pseudomonas sp. (ercppi-2) for microbial enhanced oil recovery was investigated. various mechanisms of enhanced oil recovery (eor) as a result of using ercppi-2 and its metabolic products were studied in detail. the obtained results showed that under simulated reservoir conditions, interfacial tension redu...

The microbial enhanced oil recovery (MEOR) method is an eco-friendly and economical alternative technology. technology involves a variety of uncertainties, its success depends on controlling growth metabolism. Though few numerical studies have been carried out to reduce the no attempt has made consider temperature, pressure, salinity in integrated manner. In this study, new modeling incorporati...

The community diversities of two oil reservoirs with low permeability of 1.81 × 10(-3) and 2.29 × 10(-3) μm(2) in Changqing, China, were investigated using a high throughput sequencing technique to analyze the influence of biostimulation with a nutrient activator on the bacterial communities. These two blocks differed significantly in salinity (average 17,500 vs 40,900 mg/L). A core simulation ...

Crude oil is the major source of energy worldwide being exploited as a source of economy, including Oman. As the price of crude oil increases and crude oil reserves collapse, exploitation of oil resources in mature reservoirs is essential for meeting future energy demands. As conventional recovery methods currently used have become less efficient for the needs, there is a continuous demand of d...

Column experiments were utilized to investigate the effects of nitrate injection on sulfate-reducing bacteria (SRB) inhibition and microbial enhanced oil recovery (MEOR). An indigenous microbial consortium collected from the produced water of a Brazilian offshore field was used as inoculum. The presence of 150 mg/L volatile fatty acids (VFA´s) in the injection water contributed to a high biolog...

Crude oil is a major energy source that exploited globally to achieve economic growth. To meet the growing demands for oil, in an environment of stringent environmental regulations and technical pressure, industries have been required develop novel salvaging techniques. The remaining ~70% world’s conventional (one-third available total petroleum) trapped depleted marginal reservoirs, could thus...

A significant quantum of crude oil is trapped in reservoirs and often unrecoverable by conventional oil recovery methods. Further downstream, the petroleum industry is facing challenges to remove sulfur, metal, nitrogen as well as undesirable organic compounds from the crude. Conventional secondary recovery methods such as water and gas injections helped to increase the productivity of the well...

Microbial populations associated with microbial enhanced oil recovery (MEOR) and their abundance in the Xinjiang Luliang water-flooding petroleum reservoir were investigated using 16S rRNA, nitrate reductases, dissimilatory sulfate reductase, and methyl coenzyme-M reductase-encoded genes to provide ecological information for the potential application of MEOR. 16S rRNA gene miseq sequencing reve...
