Asphaltene deposition in the reservoirs, tubbing, and surface facilities causes serious flow
assurance problems with significant economic implications. Asphaltene flow assurance …

Precipitation and deposition of asphaltene are among chronic operational problems for
recovering oil from reservoirs of high asphaltene content. The present experimental study …

The precipitation and deposition of solids are a major challenge in the production of oil and
gas. Flow assurance solids are formed because of unavoidable changes in temperature …

Crack width, a practical measurement of the damage severity in the field, is conceptually
believed to have important influence on the healing properties of asphalt materials …

Cubic equation-of-state solid models are one of the most widely used models to predict
asphaltene precipitation behavior. Thermodynamic parameters are needed to model …

A method to predict the gas/oil (GOC) and oil/tar (OTC) fluid contacts of reservoir fluid
columns containing heavy fractions and asphaltenes is presented. A new formulation and …

Asphaltene adsorption on reservoir rocks, particularly those near the wellbore, has been
debated for decades, but a long-term solution is still difficult. This is partially because …

Abstract Changes in temperature, pressure, and/or oil composition resulting from mixing with
other crude oils or gas injection often affect the solubility of asphaltenes in crude oils. This …

One of the important challenges faced during production, transport and processing of acidic
crude is metal naphthenate formation and subsequent flow assurance issues. But currently …

Asphaltene precipitation can occur during the different stages of oil production, including an
underground reservoir, wellbore, pipelines, and surface facilities. An accurate model to …
