Microwave-Assisted Heavy Oil Production: An Experimental Approach

Hascakir, Berna

Conventional enhanced oil recovery (EOR) methods, Such as steam injection, are Usually not cost-effective for deep wells and wells produced from thin pay zones, because of excessive heat loss to the overburden. For such wells, minimizing heat losses can be achieved using microwave heating. In this study, the feasibility of this method was investigated. Heavy oil samples from conceptual reservoirs (Bati Raman, 9.5 degrees API; Garzan, 12 degrees API; and Camurlu, 18 degrees API) southeast Turkey were used. Using a novel graphite core holder packed with crushed limestone premixed with crude oil and water, effects of operational parameters, such as heating time and waiting period, as well as rock and fluid properties, such as porosity, permeability, wettability, salinity, and initial water saturation, were studied. It was found that high-salinity water promotes oil production during microwave-assisted production. High water saturations lead to higher oil productions regardless of the viscosity of the oil. It was finally concluded that microwave heating could be used to stimulate heavy oil production.

Conventional EOR methods like steam-injection are usually not cost effective for deep wells and wells producing from thin pay zones, due to excessive heat loss to the overburden. For such wells minimizing heat losses can be achieved by using microwave heating assisted gravity drainage. In this study, the feasibility of this method was investigated. Heavy oil samples from conceptual reservoirs (Bati Raman (9.5 API), Garzan (12 API) and Camurlu (18 API)) in south east Turkey were used. Using a novel graphite ...
Analysis of finite element method solution of sinusoidal buckling behaviour of drill string in vertical, directional, and horizontal wellbores and comparison with analytical solutions
Cebeci, Mehmet; Kök, Mustafa Verşan; Gücüyener, İ. Hakkı; Department of Petroleum and Natural Gas Engineering (2017)
The buckling of drill string in oil, gas and geothermal wells is a critical problem that has been of interest to many researchers in the industry. Prevention of buckling of drill string is important since it may negatively affect the drilling operations. When buckling of drill string occurs, it may cause deviation control problems while drilling, inefficient load transfer to the bit, excessive torque values, even pipe failures due to fatigue. The first rigorous treatment of stability of drill strings for ve...
Random walk particle modelling of polymer injection using matlab reservoir simulation toolbox
Mamak, Gökhan; Durgut, İsmail; Department of Petroleum and Natural Gas Engineering (2017)
Enhanced oil recovery (EOR) is essential to increase the maximum recoverable oil by natural means of production. Having chosen an EOR method, the effectiveness of the method should be analyzed before applying to a reservoir since the methods are generally costly. Polymer injection is a chemical EOR process, where the injected polymer with water increases the water viscosity, and help increasing the sweep efficiency in the reservoir. In order to model the effects of polymer injection, the random-walk particl...
An experimental study on single well steam assisted gravity drainage
Akın, Serhat (2000-01-01)
Steam assisted gravity drainage (SAGD) is one of the more popular enhanced oil recovery method of producing heavy oil and bitumen. In conventional SAGD approach, steam is injected into a horizontal well located above a horizontal producer. A steam chamber grows around the injection well and displaces heated oil toward the production well. There are several variations of this process: vertical injector-horizontal producer and singlewell (SW) SAGD where only one horizontal well is used by injecting steam from...
Empirical correlations for estimating filtrate volume of water based drilling fluids
Ozbayoglu, Evren; Gunes, Cagri; Apak, Esat C.; Kök, Mustafa Verşan; Iscan, A. Gurkan (Informa UK Limited, 2005-03-01)
Standard American Petroleum Institute (API) filter press is generally used for identifying the filtrate volume of drilling fluids and works only at very low pressures. In fact, during a drilling operation, at downhole conditions, the pressures encountered are significantly higher than what is used during standard API filter press tests. A relationship between the well-known fluid properties and the filtrate volume test is developed. In this study, experiments have been conducted for different water-clay mix...
