Investigating multi cyclic gas (N2 and CO2) huff and puff have been conducted by long sandpack simulations with four different crude oils from Jiangsu oilfield. According to the production differential pressure and the production regularity during huff and puff, the production process was divided into three sections; the first one is free gas production section; the second section is low viscou...
A New Approach to Simultaneously Enhancing Heavy Oil Recovery and Hindering Asphaltene Precipitation
A new chemical compound is developed at Petroleum University of Technology to enhance the recovery of the free imbibition process and simultaneously hinder asphaltene precipitation. The compound is tested on heavy oil samples from Marun oil field, Bangestan reservoir. The effects of the chemical compound on viscosity, hydrocarbon composition, and average molecular weight of the heavy oil are in...
When the Labrecque family moved away from the 9 km2 homestead they lived on in northern Alberta in 2011, they left more than just a thriving business and an 80 year family history in the area. They abandoned most of their belongings too. The family left behind two-thirds of their children’s toys, their clothes, and even Karla Labrecque’s wedding dress. It was necessary, they say. The fumes from...
Two-stage riser catalytic cracking of heavy oil for maximizing propylene yield (TMP) process proposed by State Key Laboratory of Heavy oil Processing, China University of Petroleum, can remarkably enhance the propylene yield and minimize the dry gas and coke yields, and obtain high-quality light oils (gasoline and diesel). It has been commercialized since 2006. Up to now, three TMP commercial u...

Thermal recovery techniques including Fast-SAGD process increases the production efciency of heavy oil reservoirs. Effective parameters in this study included injection and production rates, height of the injection, production, and offset wells, production and injection cycles, and pressure of the offset wells. In this study, optimization studies were performed. The objective function was defned a...
On the basis of flow characteristics and material balance principle, a one-dimensional theoretical model of heavy-oil migration in porous media was established. The model considered micro-compressible property and nonNewtonian behavior of heavy oil. A new method, the transient method, was introduced to calculate the threshold pressure gradient in porous media. The method was designed to measure...
gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...
