Determination of microbial eor mechanisms for selected Turkish crude oils

An Experimental study on steam distillation of heavy oils during thermal recovery Tavakkoli Osgouel, Yashar; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2013) Thermal recovery methods are frequently used to enhance the production of heavy crude oils. Steam-based processes are the most economically popular and effective methods for heavy oil recovery for several decades. In general, there are various mechanisms over steam injection to enhance and have additional oil recovery. However, among these mechanisms, steam distillation plays pivotal role in the recovery of crude oil during thermal recovery process. In this study, an experimental investigation was carried o...
Development of a screening model for polymer flooding in multi-layer reservoirs ZarePakzad, Negar; Durgut, İsmail; Artun, Emre; Department of Petroleum and Natural Gas Engineering (2018) Polymer flooding is a chemical enhanced oil recovery method which aims to increase oil production from a water flooded oil reservoir by increase in water viscosity and reduction in water-oil mobility ratio. These changes result in significant increase in sweep efficiency of water comparing with water-only flooding technique. The objective of this study is to analyze the behavior of multilayer reservoirs under polymer flooding process, considering effects of reservoir characteristics, polymer properties and ...
Development of a screening model for the cyclic steam injection (CSI) process Yalgın, Gamze; Kök, Mustafa Verşan; Artun, Emre; Department of Petroleum and Natural Gas Engineering (2017) Cyclic steam injection (CSI), a single-well enhanced oil recovery method for heavy oil reservoirs, is characterized with three stages: injection, soaking, and production which altogether constitute a cycle. In this study, it is aimed to develop a screening model that can be used to accept or reject a given CSI proposal from a representative performance indicator. This indicator is estimated from a large set of reservoir & CSI design characteristics, using the screening model developed. The model has been tr...
Effects of CO₂ saturation on the recovery of the heavy oil using steam injection EOR technique Farid, Guluzade; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2014) Enhanced Oil Recovery processes include all methods that use external sources of energy and/or materials to recover oil that cannot be produced economically by conventional means. EOR processes can be classified as: thermal methods (in-situ combustion, cyclic steam injection, steam flooding), chemical methods (alkaline, polymer, foam, or surfactant/polymer injection), and miscible methods (CO2, nitrogen, hydrocarbon, or flue gas injection). Steam flooding involves continuous injection of steam to displace o...
Optimization of CO₂ EOR and storage design under uncertainity Bender, Serdar; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2016) The combination of CO₂ enhanced oil recovery (EOR) and permanent CO₂ storage in mature oil reservoirs have the potential to provide a critical near-term solution for reducing greenhouse gas emissions. In the literature, although there are many studies about CO₂ storage and EOR, only a few studies have focused on maximizing both the oil recovery and the CO₂ storage. Moreover, these studies are either experimental or conducted using synthetic reservoir models. Typically, pure CO₂ has the property of mixing wi...
