Paper presented at the SPE Canada Heavy Oil Conference, September 28–October 2, 2020
Paper Number: SPE-199910-MS
... In this paper, simulation work has been conducted for the evaluation of electromagnetic heating for oil sands recovery. In electromagnetic heating, frequency is defined as the number of oscillations of electromagnetic energy per second. In general, frequencies ranging from 3 kHz to 300 GHz...

Paper presented at the SPE Canada Heavy Oil Technical Conference, March 13–14, 2018
Paper Number: SPE-189714-MS
... Now going back to f = 1MHz, by increasing counter-current flow rate, exact field and Lambert's law are becoming less different shown Figure 5 and 6 for two frequencies. This is because when more fluid comes toward the antenna, the effect of heat convection becomes more dominant than...

... as a function of the state of the system in regard to temperature, pressure, frequency, etc. and so it becomes necessary to quantify these dependencies to adequately estimate penetration depth ( Hascakir and Akin 2009 ). Abstract Electromagnetic waves as a viable means of introducing heat energy...

Paper presented at the SPE Canada Heavy Oil Technical Conference, March 13–14, 2018
Paper Number: SPE-189771-MS
... Abstract SAGD is an energy-intensive process with large amount of greenhouse gas (GHG) emissions and required water treatment. One option to reduce emissions and water is to use electromagnetic (EM) heating in either the induction (medium frequency) or radio frequency (RF) ranges. Since...

Paper presented at the SPE Canada Heavy Oil Technical Conference, June 7–9, 2016
Paper Number: SPE-180695-MS
... Abstract Conventional steam injection processes for thermal heavy oil recovery are generally limited to relatively shallow, thick, permeable, and homogenous reservoirs. An alternative thermal recovery process is to use electromagnetic (EM) energy to generate heat. Radio frequency heating is one...

.... Additionally, high temperatures are not always indicative of inflow and cooler liner temperatures may not signify the absence of production contribution. Distributed acoustic sensing (DAS), which is used to measure acoustic frequency and intensity in 1-m intervals along the length of a fiber-optic line...

... is ranging between three to several months. A variety of processes are used to minimize time of start-up phase such as: electro-magnetic (EM) heating either induction (medium frequency) or radio frequency (RF) ranges. Knowing the hot-zone size formed by steam circulation and benefit of simultaneous EM...

.... This initial study has therefore involved investigating a range of synthetic oil sands systematically prepared from bitumen, water, sand and clay, to compare the behaviour with results obtained from a real core sample (obtained from a BP asset). The low-frequency dielectric spectroscopic analysis (10 -2 to 10...

... of the wetting and non-wetting phases: In general, radiation with frequencies within a range of 10 to 100 MHz are referred to as radio frequencies (RF), and in the range of 300 MHz to 300 GHz as microwave (MW), and corresponding wavelengths from 1 to 0.001 m. The process is defined as EMH within this range...
