... resulting in an increase in the oil recovery efficiency. It can be inferred that MEOR is a "high-risk, high reward" process, depending on whether the microorganisms can produce oil recovery-enhancing chemicals by utilizing the residual oil within the reservoir as a carbon source. The high risk...

...). But the cost of some of these EOR methodologies and their subsequent environmental impact is daunting. Herein, the environmental and economic advantage of microbial enhanced oil recovery (MEOR) makes it the point of interest. Since, there is no need to change much-invested technology and infrastructure, amidst...

... mechanisms involved in MEOR that contribute to an additional oil recovery are not fully understood so far. This work aims to investigate the MEOR mechanisms using microfluidic technology, among others bioplugging and changes in fluid mobilities. Further, the contribution of these mechanisms to additional oil...

... Abstract Wintershall is conducting a technology project for development and field application of MEOR (Microbiologically Enhanced Oil Recovery) in collaboration with BASF. The successful results of the laboratory phase led to a first small confined pilot Huff'n’ Puff (HnP) in a Wintershall...

..., reduced productivity of wells and increased corrosion. The numerical assessment of the souring and its successful inhibition for an MEOR (Microbial Enhanced Oil Recovery) application in a Wintershall mature oil field is the subject of this paper. The numerical assessment of the biogenic souring...

... Abstract MEOR (microbial enhanced oil recovery) is known as low-cost and easy to apply EOR technology. It uses the fact that natural occuring microrganisms in the oil reservoir can be stimulated to create effects that may result in mobilizing oil and sweeping it to the production well. During...

... Abstract This paper provides an update on a microbial enhanced oil recovery (MEOR) project conducted by Wintershall and BASF. Overall nutrient development and planning of a single well field trial (huff'n'puff, HnP) including risk management are described. A nutrient solution is tailored...

.... After disassembling the sand column, the containing sand was pushed out of the steel body using a cylindric "chisel". Thus, the sand could be assigned directly to the corresponding heights of the sandpack and was subject to further analysis. Microscopy Introduction Abstract MEOR (microbial...

... to inoculate the reservoir with a microbe that under the optimal nutrient conditions will express a biopolymer as a film, reduce the size of pore throats and reduce the apparent permeability. The microbe and the nutrients are tailored to the conditions of each reservoir thus giving MEOR the greatest chance...

... Abstract The workflow and the results of the work packages of a Microbial Enhanced Oil Recovery (MEOR) project aiming at a pilot are introduced and discussed. An enrichment culture consisting of a community of various microbial species derived from one of the Wintershallfields shows good growth...

... there is no commercial reservoir simulator used to model the growth phase of microbial enhanced oil recovery (MEOR), due to process complexity and significant dependency on laboratory data. One of the work packages of the project "MEOR Studies" being conducted by Wintershall is dealing with the modeling of MEOR to allow...

... was reported to be 6 million BO. With 31.5 million barrels OOIP, 19% of the OOIP had been recovered from the Big Wells Field when well spacing was on 80 acres. (Reviere, R. H. 1986). Oil Release Mechanism Unlike many previous attempts at MEOR, this organic oil recovery process does not attempt...

... Abstract Using a breakthrough process, which does not require microbes to be injected, over one hundred Microbial Enhanced Oil Recovery (MEOR) applications have been conducted since 2007 in producing oil and water injection wells in the United States and Canada. On average, these applications...

... Lazar et al. (1999) have suggested the employment of microorganisms to reduce the fraction of long-chain n-alkanes in biotechnological processes for waxy crude oil recovery. In particular, from the standpoint of MEOR, oil-degrading microorganisms which can degrade heavier components of crude...

... Abstract A Microbial Enhanced Oil Recovery (MEOR) process was successfully applied to a mature waterflood in Southern California, using indigenous microbes that normally remain dormant during the producing life. Certain indigenous microbial species can be activated in waterflood reservoirs...

... Abstract Progression of Microbial EOR (MEOR) technology from the laboratory towards field trial is described. An overview is provided of evaluation steps and field trial risk management through laboratory testing and numerical simulation, together with assessment of operational factors which...

... Abstract Enhanced oil recovery techniques are usually controlled by the cost associated with them as the fluctuation in the oil price, over the last years, is now commercially accepted. Microbial Enhanced Oil Recovery (MEOR) is one of the technologies that can potentially be implemented...

... Abstract One thermophilic anaerobic oil-degrading bacterium was successfully isolated from reservoir brine of Yabase oilfield, INPEX Corp., Akita, Japan. The potential of the isolated bacterium as a candidate for Microbial EOR (MEOR) was estimated in this study. This bacterium was identified...
