... Abstract A comprehensive chemical enhanced oil recovery (CEOR) laboratory evaluation program was carried out to compare surfactants for alkali-surfactant-polymer (ASP) and surfactant-polymer (SP) implementation in a giant Middle East sandstone oil reservoir. The efficacies of ASP and SP floods...

... Abstract In-situ combustion (ISC) is a promising thermal enhanced oil recovery (EOR) method for heavy oils. However, its field application is still limited due to difficulty in ignition, low combustion efficiency, unstable combustion front, etc. To improve the success rate of ISC process, we...

... permeability reduction thief zone oil recovery Introduction Improving the performance of water flood is imperative for reservoirs with high permeability contrast and high mobility ratio. The conformance problems are exacerbated more when there is a crossflow within the vertical direction. Over...

... Abstract Synthetic polymers in the emulsion form have been exploited for enhanced oil recovery applications especially in harsh environments for instance offshore or remote onshore locations. Polymer solutions can be prepared on-the-fly using saline make-up water like formation water or sea...

... their strong thermal stability and enhanced oil recovery capability. The recovery improvement mechanisms for the different chemical additives and different injection strategies were identified through flow characteristics, emulsifying ability, viscosity reduction capability, and wettability alteration...

... be determined in order to meet the global market demand for oil, which can be done using Enhanced Oil Recovery (EOR) techniques. In Kuwait, one of the EOR methods that could be applied is the use of Low-Salinity (LoSal) Water Flood. Results from previous research have clearly shown that LoSal water injection...

... Abstract This article describes both the implementation of a structured review process of field performance for managing an existing waterflood in North Kuwait and summarizes how this process can lead to enhanced oil recovery. The aim of the review process, applied to the Upper Burgan...

... model was revisited. Consequently, this simulation model was updated and calibrated to reflect field and lab observations. In addition, lab tests that demonstrated good transport and oil recovery performances of a selected polymer in low permeability reservoir cores were modeled to provide parameters...

... Design (CCD) was employed to build the proxy model to determine the incremental oil recovery (ΔFOE) as a function of seven reservoir and operating parameters (permeability, porosity, ratio of vertical to horizontal permeability, cyclic length, bottom hole pressure, ratio of CO 2 slug size to water slug...

... Abstract With the global increase in the demand for crude oil, the need to develop enhanced oil recovery techniques is crucial. These techniques must focus on how to displace greater volumes of trapped oil from within a given rock. Since carbonate reservoirs constitute over half of the world's...

... Abstract Per recent analyses, in the near future, over half amount of the oil extracted globally will require some form of enhanced oil recovery (EOR) technique. Existing literature and historical investigations suggest that in oil reservoirs having viscosities between 10 — 150 m. Pa.s...

... is still low as 5-10%. Therefore, seeking for techniques to enhance oil recovery in these complex plays is inevitable. In this paper, two different approaches have been integrated to investigate the feasibility of three different miscible-gases which are CO 2 , lean gases, and rich gases. Firstly...

... Abstract Water-alternating-gas (WAG) injection is a widely used enhanced oil recovery (EOR) technique. The performance of WAG injection is affected by a number of design parameters; including the size of the gas and water injection slugs as well as their order of injection. Since the prediction...
