Abstract Chemically enhanced oil recovery methods can provide a solution to increase recovery. Of these, surfactant- polymer flooding is common. Efficient selection of polymers and surfactants essential for successful EOR project. Detailed lengthy task that involves number studies. Our goal create fast method based on which the most promising be selected.

While Carbon Dioxide based Enhanced Oil Recovery (CO2 -EOR) is often regarded as one of the most economically viable methods carbon capture, utilization and storage (CCUS), little known about existing CO2 supply contracts in -EOR industry. By studying a sample 103 sales U.S. 1980s 1990s, this paper aims to find out what drives key terms these contracts. In particular, special price adjustment c...

Applications of Enhanced Oil Recovery (EOR) are highly required and needed in Sudan to keep oil supply at stable levels. ”FUL” Oilfield has shallow reservoir affected by big boundary bottom water drive with high crude viscosity. This research, through a comprehensive analysis the current producing wells, perforation intervals, CO2 temperature analysis, steam parameters optimization which using ...

core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating co2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. the core samples were provided from a low permeability mixed wet oil reservoir at 156 °f and 1900 psia. in addition, very few studies of surfactant adsorption on carbonate mine...

Well blowout rates in oil fields undergoing thermally enhanced recovery (via steam injection) in California Oil and Gas District 4 from 1991 to 2005 were on the order of 1 per 1,000 well construction operations, 1 per 10,000 active wells per year, and 1 per 100,000 shutin/idle and plugged/abandoned wells per year. This allows some initial inferences about leakage of CO2 via wells, which is cons...

The North Burbank Unit, located in Osage County, was originally discovered in 1920. It has an extensive history of activity, including primary depletion, produced gas cycling, and water and polymer flooding to the point of very high water cut at current conditions. The current oil production rate in the North Burbank Unit is approximately 1,400 BOPD from 360 active wells at a water cut of 99.5%...

The idea of injecting low salinity water into a petroleum reservoir is not novel and was often used in the 70’s prior to the injection of surfactant. Yet, recently it was shown that simply injecting sufficiently low salinity water improves oil recovery (LoSalTM). Many possible mechanisms concerning Low salinity waterflood have been proposed in the literature. This paper describes an experimenta...

Lack of climate policy and CO2 markets along with a global economic slowdown suggest that we need to rethink our approach to demonstrating CCS at a commercial scale. Austerity measures make it likely that public funding will be tight in coming years, and there is a striking need to ensure that limited funds are spent optimally. Quantitative tools exist for aiding decision making under uncertain...

CO2 mediated enhanced oil recovery (CO2-EOR) may lead to methods of CO2 reduction in the atmosphere through carbon capture and storage (CCS); therefore, monitoring and verification methods are needed to ensure that CO2-EOR and CCS activities are environmentally safe and effective. This study explored vegetation growth rate to determine potential ecological effects of emissions from CO2-EOR acti...

The recent development of tight oil reservoirs has led to an increase in oil production in the past several years due to the progress in horizontal drilling and hydraulic fracturing. However, the expected oil recovery factor from these reservoirs is still very low. CO2-based enhanced oil recovery is a suitable solution to improve the recovery. One challenge of the estimation of the recovery is ...
