Experimental study on asphaltene precipitation induced by CO2 flooding

Influence of CO2 Dissolution and Asphaltene Precipitation on Oil PVT and Recovery

Developing a Fuzzy Logic Model to Predict Asphaltene Precipitation during Natural Depletion based on Experimental Data

Experimental Investigation and Modeling of Asphaltene Precipitation Due to Gas Injection

Asphaltene instability is one of the major problems in gas injection projects throughout the world. Numerous models have been developed to predict asphaltene precipitation; The scaling equation is an attractive tool because of its simplicity and not involving complex properties of asphaltene. In this work, a new scaling model is presented to account  for asphaltene precipitation due to gas ...

Prediction of Solvent Effect on Asphaltene Precipitation at Reservoir Conditions

The aim of the current study is to evaluate the effects of inhibitors or solvents on asphaltene precipitation under reservoir conditions. To this end, the interaction between live oil and solvent, and its side effects on precipitated/dissolved asphaltene were predicted via Miller’s entropy modified polymer solution theory under reservoir conditions. Then, the adjustable parameters of the model ...

A Solution Model for Predicting Asphaltene Precipitation

Formation of asphaltene deposition during oil production, processing and synthesis is known as a fundamental problem of petroleum reservoir worldwide. Asphaltene is a petroleum fraction that can lead to increasing the operating costs in these industries. Variations in operational pressure, temperature and fluid composition are generally the significant cause of asphaltene precipitation. In ...
