Modeling of Asphaltene Precipitation and Deposition

, 2017
The tendency of Asphaltene to deposit and block tubing can potentially lead to production loss and significant cost of remediation. Unlike other deposits, the deposition behavior of Asphaltene is still not fully understood and is hindered by asphaltene ...

Influencing mechanisms of solid-phase asphaltene precipitation in crude oil of Yongjin Oil Field, Junggar Basin

Shiyou shiyan dizhi
Solid-phase asphaltene precipitation and deposition, commonly occurring during reservoir development, lead to reservoir damage and production well blockage, seriously affecting crude oil exploitation and reducing economic efficiency.

Laboratory investigation of asphaltene-induced formation damage

Journal of Petroleum Exploration and Production Technology, 2018
The purpose of this study is to evaluate the degree of formation damage caused by asphaltene deposition in the pore throats in case of oilfield operation. Many wells in the Samara region oilfields are operated under high reservoir drawdown, with downhole

Experimental Study of Asphaltene Deposition During Different Production Mechanisms

, 2011
Sudden changes in key parameters such as pressure, temperature, and fluid composition may result in asphaltene precipitation and deposition, consequently reducing permeability and porosity as well as well injectivity and productivity.
