Oxidation Behavior and Kinetics of Light, Medium, and Heavy Crude Oils Characterized by Thermogravimetry Coupled with Fourier Transform Infrared Spectroscopy
TL;DR: In this article, the authors used thermogravimetry coupled with Fourier transform infrared spectroscopy (TG-FTIR) to investigate the oxidation mechanism of crude oils, and the results indicated that the entire oxidation process can be divided into three main reaction intervals: low-temperature oxidation (LTO) interval (<400 °C), coking process (400-500 °C) and high temperature oxidation (HTO) interval (500-650 °C).
Journal ArticleDOI
Low-Temperature Oxidation and Characterization of Heavy Oil via Thermal Analysis
TL;DR: In this paper, the potential of HPAI without ignition for deep, high pressure, heavy oil reservoirs (Tahe oilfield, Tarim Basin, China) was evaluated.

TL;DR: In this article, the difference and connection of oxidation behavior between crude oil and its SARA fractions were revealed by using differential scanning calorimetry (DSC) and thermogravimetric (TG) techniques.

TL;DR: In this article, the authors investigated the performance of high sulfur-content heavy oil at sub-critical, near-critical and supercritical water (SCW) conditions, and showed that a viscosity reduction from 2073 to 1758mPa was achieved with a slight removal of sulfur (mainly sulfur) and the generation of a small amount of light and non-condensable hydrocarbons in gas phase (C1−C4, isoalkanes and alkenes, H2S, CO2 and H2, etc.).
Journal ArticleDOI
Investigation into the migration of polymer microspheres (PMs) in porous media: Implications for profile control and oil displacement
TL;DR: In this article, a profile control agent, named polymer microspheres (PMs), was synthesized by inverse emulsion polymerization and its physical properties including morphology, particle size distribution, dispersibility strength and hydration swelling property were thoroughly examined.
