This paper presents a review of the electrical heating method for heavy oil recovery based on past, current, and future prospects of electrical heating. Heavy oil is one of the potential crude oil used as a link to reduce the crisis of light oil used today. The obstacle of heavy oil is a high viscosity and density in which thermal injection is a method for heavy oil recovery, but it results in economic and environmental issues. Electrical heating is one of the thermal methods by transferring heat into the reservoir. The basic process of electrical heating is to increase the mobility of the oil. Because the temperature rises, it can reduce oil viscosity and makes it easier for heavy oil to flow. The past and current developments have been carried out to fill up the gap of electrical heating projects. The future prospects must meet energy efficiency, and the excessive heat will damage formation that must be tackled in the future prospect. the works adopt several electrical heating projects and applications in the world where the works give a brief future prospect of electrical heating.

“…Besides, CSS also is more economically profitable. With CSS injections a few months to produce results that are quite maximum with a total of recovery factor of 40% (Putra et al, 2011). CSS also has been done for paraffinic-type crude oil, and it shows some promising result (Hidayat & Abdurrahman, 2018).…”

This paper presents a review of electrical heating for the recovery of heavy oil which the work adopts methods used in the past and the prospects for crude oil recovery in the future. Heavy oil is one of the crude oils with API more than 22 which has the potential to overcome the current light oil crisis. However, high viscosity and density are challenges in heavy oil recovery. The method is often used to overcome these challenges by using thermal injection methods, but this method results in economic and environmental issues. The electrical heating method could be a solution to replace conventional thermal methods in which the methodology of electrical heating is to transfer heat into the reservoir due to increasing oil mobility. Because the temperature rises, it could help to reduce oil viscosity, then heavy oil will flow easily. The applications of electrical heating have been adopted in this paper where the prospects of electrical heating are carried out to be useful as guidelines of electrical heating. The challenge of electrical heating is the excessive heat will damage the formation that must be addressed in the prospect of electrical heating which must meet energy efficiency. The use of Artificial intelligence becomes a new technology to overcome problems that are often found in conventional thermal methods where this method could avoid steam breakthrough and excessive heat. Therefore, it becomes more efficient and could reduce costs.

Heavy oil has attracted global attention due to its huge volume of original oil in place. However, there are numerous operation and economic challenges during the recovery of heavy oil due to its high-viscosity and high-density. Thermal recovery methods such as steam injection is viable and commonly used to recover heavy oil and bitumen primarily by thermally altering oil viscosity and improving the displacement of heavy oil. However, there are significant heat losses before the steam reaches the heavy oil, in addition to the concerns of high cost and emission of greenhouse gases. One of the promising new heavy oil recovery approaches is generating steam, in-situ, using chemical reaction to reduce the oil viscosity, improve the mobility ratio, and enhance the heavy oil displacement. The objective of this work is to introduce a novel heavy oil recovery process using in-situ steam generated by thermal and chemical reaction and analyze its recovery performance compared with conventional steam injection method from the economic point of view, as well as based on the achieved net present value (NPV) of each technique. Sensitivity analysis of the proposed recovery processes to different operational parameters is introduced. The CMG STARS™ Simulator is used in this work to simulate reservoir models with different operational parameters. The recovery performance of the proposed technique outperformed the conventional steam flooding method and achieved higher NPV after ten years of production. This is the first time to use NPV and consider all economic parameters to analyze the performance of the developed recovery process of in-situ steam generation by chemical reaction. This research shows that the recovery of the proposed method is economic, and applicable to the reservoirs which are not viable for conventional steam flooding methods and it is a step forward to eliminate CO2 emissions associated with thermal recovery processes.
