The high viscosity and low fluidity of heavy crude oil hinder its sorption by conventional porous sorbents, so the efficient clean-up of such heavy crude oil spills is challenging. Recently, Joule heating has been emerging as a new tool to reduce the…
Thermal enhanced oil recovery methods such as hot water flooding, steam drive, cyclic steam injection, steam-assisted gravity drainage, in-situ combustion, and electrical heating involve multiphase and multicomponent thermal flow with phase change…
Overhauser dynamic nuclear polarization (ODNP) in solutions of various paramagnetic complexes has been studied for 60 years, but only in recent years has found applications of broad interest to biophysical and biomedical sciences, for the…
The formation and decomposition of hydro-peroxides are the key stages of combustion. These stages strongly depend on the several factors accelerating or slowing this process. The aim of this work is to estimate experimentally which oil components act…
The present study demonstrates a promising approach for production of bio-crude oil via hydrothermal liquefaction of microbial biomass grown in large-scale open raceway pond. Three key attributes to achieve process feasibility are co-cultivation of…
The asphaltene fractions from initial crude oil of Ashal'cha field were extracted for the further investigation. Moreover, the non-catalytic and catalytic products of aquathermolysis in the presence of cobalt-containing catalyst precursor and…
Thermal enhanced oil recovery methods such as hot water flooding, steam drive, cyclic steam injection, steam-assisted gravity drainage, in-situ combustion, and electrical heating involve multiphase and multicomponent thermal flow with phase change…
Field-scale reservoir simulation of In-Situ Combustion (ISC) process has been a grey area worldwide, due to the complexities of reactions involved and availability of kinetic model that can cover every aspects of an ISC process properly i.e.…
In the process of heavy oil development, steam stimulation is usually used. In steam stimulation, the oil field is produced by depleted development after the end of shut in well. The magnitude of reservoir compressive coefficient is significant for…
Most of the heavy oil productions in the world are through enhanced oil recovery (EOR) methods only and predominantly by thermal EOR techniques. This is mainly due to low primary recovery of heavy oil because of high viscosity leading to low…
Shengli Oilfield is rich in heavy oil resources, and steam stimulation is the main development method. Most of the reservoirs face problems such as low recovery and serious steam enthalpy. The study of flow field distribution law has become the focus…
An approach to modeling the processes of non-isothermal multiphase flow in oil reservoir is considered. The approach is based on implicit calculation of pressure using the finite element method and explicit calculation of phase saturations. The…
Xinjiang oil field is at the heart of the Belt and Road Initiative (BRI), and special technologies like hydraulic fracturing treatments and thermally enhanced oil recovery technology were applied for unconventional petroleum productions in the…
Lloydminster area that straddles Alberta and Saskatchewan border contains vast amounts of heavy oil deposits in thin unconsolidated formations. It is believed that the heavy oil resource volume is in the 50 to 70 billion bbl range which makes it a…
Toxic vapor emissions (TVEs) from crude oil and condensate storage tanks contain volatile organic compounds which are precursors for ground level ozone formation. Vapor recovery units have been proposed for the control of TVEs but come with high…
