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...

Applications of Non – Destructive Testing (NDT) are very broad varying from the medical to heavy industries. Several advanced NDT methods, mainly developed form of the conventional methods, are used to render the technique more flexible and easier to interpret. Ultrasonic Phased Array method can be employed in almost any test, where conventional Ultrasonic Testing (UT) has traditionally been used. The benefits of Phased Array technology over conventional UT come from its ability to use multiple elements to ...
Characterization of plus fractions for low gas-oil ratio black oil samples in Turkey
Türkmenoğlu, Artuğ; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2016)
Pressure - Volume - Temperature (PVT) analyses simulate the reservoir fluid behavior while flowing from the reservoir to the surface under varying pressure, volume and temperature conditions. There are several PVT simulators that perform PVT calculations. Accurate characterization of a fluid is very important for further studies and reservoir simulations in all reservoir engineering aspects. Because there are a few equations of state and many types of reservoir and reservoir fluids, experimental data does n...
