Influence of Geological Factors on Asphaltene Precipitation From Crude Oils in Tuoputai Area, Tarim Basin, Northwestern China

open access: yesJournal of GeoEnergy, Volume 2026, Issue 1, 2026.
Asphaltene precipitation frequently occurs in oil wells within the Tuoputai area of the Tarim Basin, significantly hindering production efficiency. In addition to external factors, such as temperature and pressure, the effects of geological factors on asphaltene precipitation warrant further investigation.
