“…In 2010, 55% of its tar sands production was from mining operations with a maximum burial depth of 75 m while in situ operations produced, the other 45% had deeper depths. The proportion of non-upgraded bitumen exports is projected to increase from 42% of total production in 2009, to 52% by 2019 (Spirov et al, 2013; Rudyk and Spirov, 2014). …”

The growing global demand for sustainable technologies that improves the efficiency of petrochemical processes in the oil industry has driven advances in petroleum biotechnology in recent years. Petroleum industry uses substantial amounts of petrochemical-based synthetic surfactants in its activities as mobilizing agents to increase the availability or recovery of hydrocarbons as well as many other applications related to extraction, treatment, cleaning, and transportation. However, biosurfactants have several potential applications for use across the oil processing chain and in the formulations of petrochemical products such as emulsifying/demulsifying agents, anticorrosive, biocides for sulfate-reducing bacteria, fuel formulation, extraction of bitumen from tar sands, and many other innovative applications. Due to their versatility and proven efficiency, biosurfactants are often presented as valuable versatile tools that can transform and modernize petroleum biotechnology in an attempt to provide a true picture of state of the art and directions or use in the oil industry. We believe that biosurfactants are going to have a significant role in many future applications in the oil industries and in this review therefore, we highlight recent important relevant applications, patents disclosures and potential future applications for biosurfactants in petroleum and related industries.

“…In the SAGD process, a pair of horizontal wellbores or pipes (an injector and a producer), is drilled into oil sands, 80-1000 meters deep [46,47], depending on the reservoir. Steam is injected from above-surface facilities into the injector, then rises, condenses, and washes the hot bitumen along with condensed water into the producer well that is 3-5 m below the injector well.…”

“…However, heavy oil, usually characterized by its high viscosity, high density, small gravity, and low H/C ratio (1.2-1.4) cannot be directly refined by existing processes [2,10]. Additionally, high concentrations of heteroatoms (such as nitrogen, sulfur, nickel, and vanadium) accumulated in heavy oil will cause serious environmental concerns if not disposed [6,12,13]. Therefore, research on the technologies of upgrading heavy oil has, globally, received continuous attention.…”

Abstract:With the growing demand for energy and the depletion of conventional crude oil, heavy oil in huge reserve has attracted extensive attention. However, heavy oil cannot be directly refined by existing processes unless they are upgraded due to its complex composition and high concentration of heteroatoms (N, S, Ni, V, etc.). Of the variety of techniques for heavy oil upgrading, supercritical water (SCW) is gaining popularity because of its excellent ability to convert heavy oil into valued, clean light oil by the suppression of coke formation and the removal of heteroatoms. Based on the current status of this research around the world, heavy oil upgrading in SCW is summarized from three aspects: Transformation of hydrocarbons, suppression of coke, and removal of heteroatoms. In this work, the challenge and future development of the orientation of upgrading heavy oil in SCW are pointed out.
