Methods of microbial enhanced oil recovery
Among the most promising new methods is microbial enhanced oil recovery (MEOR)- sending genetically-engineered microorganisms deep underground to send oil up into waiting arms. One of the chief problems in oil production is getting all of it -- it's not as easy as drilling a hole in the ground and sucking it out. Microbial Enhanced Oil Recovery 73 great deal of rocks and fluids sampling and also laboratory investigations. In general, EOR processes can be classified into four main cate gories as thermal methods, chemical methods, miscible or solvent injection, and microbial methods. 4.1 Thermal processes Microbial enhanced oil recovery. wellbore clean up removes mud and other debris blocking the channels where oil flows through; well stimulation improves the flow of oil from the drainage area into the well bore; and. enhanced water floods through stimulating microbial activity by injecting selected These include chemical enhanced oil recovery (EOR) methods such as polymer flooding, surfactant flooding, alkaline flooding, etc. or the use of thermal measures such as injection of steam or in situ combustion. Another tertiary method of oil recovery is microbial enhanced oil recovery, commonly referred to as MEOR. Actually, there are several ways in which microorganisms can enhance oil recovery other than what is commonly referred to as MEOR. For example, microorganisms can be used to According to the invention, there is provided a method of microbial enhanced oil recovery for recovering oil from an oil-bearing rock formation, the formation including an inlet and an outlet, the method comprising: injecting water containing a source of vitamins, phosphates and an electron acceptor into the formation, New AERO Technology’s Activated Environment for Recovery of Oil (AERO ™) technology is an established novel biological EOR method in which customized nutrients are injected into the reservoir to activate the native subsurface beneficial microbes. The ensuing microbial activity blocks the “Thief Zones” (high-permeable zones) and improves oil mobility, which ultimately leads to increased production and Proved Developed Reserves (PDP), reduced water cut, in both sandstone and carbonate

5 Mar 2019 Microbial enhanced oil recovery (MEOR) is a method that utilises bacteria or bioproducts to alter rock–fluid properties. It is suggested in 1926 27 Nov 2007 Abstract Microbial enhanced oil recovery (MEOR) represents the use of petroleum crises in 1973, the EOR methods became less profitable. Conventional methods used to recover oil from reservoirs leave the majority of oil in place. Enhanced oil recovery is used to access trapped oil and increase. 6 Mar 2020 The production process of crude oil is being optimized by employing several recovery techniques including thermal methods, gas injection, and 19 Nov 2019 Microbial Enhanced Oil Recovery (MEOR) is a biological technology that well in EOR techniques with moment and range from the injection. of biotechnology to improve residual crude oil production from oil wells as a tertiary oil recovery method known as “microbial enhanced oil recovery” (MEOR).
