Determination of the molecular structure of asphaltenes, especially in their native
environment, is a formidable challenge in petroleum chemistry. Here we demonstrate that a …

Asphaltenes precipitation during carbon dioxide injection to enhance recovery has been
considered as one of the major challenges in the tertiary production phase. The effects of …

Here, we present a case study on a Wyoming well with known asphaltene deposition issues
as a result of natural depletion. Field deposits and crude oil from the same well were …

Asphaltenes precipitation during carbon dioxide injection to enhance recovery has been
considered as one of the major challenges in the tertiary production phase. How CO2 would …

Asphaltene precipitation continues to be one of the major problems during the carbon
dioxide enhanced oil recovery process. Supercritical carbon dioxide is injected into oil …

Significant effort has been dedicated to understand the variables affecting asphaltene
precipitation. Based on years of research, it is well known how variables such as …

An extensive CO2 EOR study was done for one of a super giant oil field reservoir in offshore
Abu Dhabi. This study aimed to evaluate the effectiveness of CO2 injection to the target …

Crude oil deposition in oil transfer pipelines and bore wells afflicts many oil reservoirs.
Asphaltenes play a major role in this process because of their tendency to precipitate in …

Abstract Changes in operating conditions such as pressure, temperature and composition of
the oil can trigger asphaltene deposition during oil recovery operations. In the present work …

As part of an Enhanced Oil Recovery (EOR) research program, Asphalting precipitation
processes were investigated for a Kuwaiti dead oil sample using different hydrocarbons and …
