Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

Application of enhanced oil recovery methods in Kazakhstan has been ongoing for decades
alongside the continued discovery of new oil and gas fields in the Pre-Caspian Basin. The …

Since its initial proposal, steam-assisted gravity drainage (SAGD) has become a key
technology of heavy-oil recovery. Due to the large heat loss and high energy consumption in …

In recent years, there has been growing interest in the use of carbon fibers for a wide variety
of applications, including automotive, aerospace, wind turbine, sporting goods, energy …

Asphaltenes precipitation within reservoir pores or production flowlines can severely
hamper the petroleum-extraction process. Although the effect of temperature and pressure …

Complex molecular structure, high impurity content, and self-association tendency of
asphaltenes make the determination of their phase behavior very difficult. Because …

The presence of significant amounts of injected steam and heat loss are unavoidable issues
occurred that are observed during the steam-assisted gravity drainage (SAGD) process in …

The residual oil saturation determination is critical for the performance evaluation of any
Enhance Oil Recovery (EOR) methods. The existing residual oil saturation determination …

Solvent-steam processes gained popularity in recent years in the extraction of high-
asphaltenes-content heavy hydrocarbons. However, while solvent selection is key for the …

This study investigates the effect of clay type on the performance variations of steam-
assisted gravity drainage (SAGD). Two SAGD experiments at identical experimental …
