Flue gas injection for heavy oil recovery
The main advantages of the flue gas injection are low cost, readily available sources for heavy oils and non-thermal methods such as gas and chemical injection [1]. In the This gas injection technique increases oil recovery by the pressure PDF | The surface steam injection is the most common enhanced oil recovery ( EOR) process used in heavy oil production. Nevertheless, there are | Find, read Secondly, the CO2 and flue gas were injected into the CO2 and flue gas transfer cylinders, respectively, and pressurized to the reservoir pressure under the 16 May 2013 formation thickness, oil viscosity, and injection data, such as injection volume, Key words: Heavy oil, Bohai Bay, flue gas, offshore.
EOR enhanced oil recovery ESP electrostatic precipitator FGD flue gas desulphurisation focus of this report is on flue gas treatment for CO 2capture at coal-fired plants, so it includes post-combustion capture and on the fate of any trace impurities in the flue gas such as heavy metals.
There are a number of ways to access heavy oil and bring it to the surface. Primary recovery occurs when the energy used to expel oil comes from the These artificial methods include water injection, natural gas reinjection and CO2 (THAI) is a method that employs combustion—which liquefies the heavy oil so it can 7 Dec 2015 During the second phase water and gas are injected into the well to push oil to the Other methods include in-situ combustion, where the reservoir is heated The injection of steam lets heat the crude oil in the formation thus A natural gas injection application is one of many enhanced oil recovery introduces heat into heavy oil or an underperforming reservoir to enhance oil flow . mixed the combustion gas and a bank of distilled solvent all act to drive oil in front 13 Apr 2017 Enhanced oil recovery techniques can loosely be grouped into CO2, N2, methane, ethane, propane, butane, flue gas and combinations thereof. Heavy Oil Production With EM Preheat And Gas Injection, October 4, 2016 28 Sep 2015 Depending on the interaction between injected gas and oil, the process CO2 or flue gas, should not results in large incremental oil production due to in the crude oil to form additional volumes of surfactant in the reservoir.
22 Jan 2019 injection and production wells and on surface equipment. o here i s a direct Flue gas flooding is suitable for heavy oil reservoirs. tlere, the.
The injection of the flue gas conveniently is disposed of and further acts to repressurize the formation which otherwise becomes depressurized when depleted of natural gas. Accordingly, environmental and economic advantages are realized with the methodology. US20060243448A1 - Flue gas injection for heavy oil recovery - Google Patents A comparative study was conducted to examine the efficiency of flue gas injection compared to CO 2 injection. • Effect of injected gas type, gas solubility and operating parameters on storage and recovery were investigated. • CO 2 injection leads to higher oil recovery and CO 2 storage, if injection continued for at least 25 years. Before An alternative to air injection is the flue gas (which contains nitrogen and carbon-dioxide) produced from the combustion of oxygen contained in the air to sweep oil. This EOR technique, when applied to light oil is known as light oil air injection while in heavy oil reservoir, it is called in-situ combustion. I/We claim: 1. A method for recovering heavy and bitumen oil from a subterranean formation containing heavy oil and bitumen, comprising: providing a fuel; burning said fuel in a flue gas recirculation circuit to produce a flue gas for injection into said formation; and injecting said flue gas into said formation to displace said heavy oil and bitumen. During this study on heavy crude oil, three different gases: pure CO 2, pure N 2, and their mixture as synthetic flue gas injection; were used to study the performance of isothermal GOGD process. It was found that the oil recovery before gas breakthrough was mostly from the fracture; however the injected gas mostly affected the amount of oil Laboratory Study on Steam and Flu e Gas Co-injection for Heavy Oil Recovery L.S.

Use flue-gas assisted cyclic steam injection for improved oil recovery from low-permeability heavy oil reservoirs. • Reveals the role of gaseous additives such as CO 2 or flue-gas on the size of steam chamber.. Evaluate the efficiency of different additives on improving the recovery performance.
