The problems associated with asphaltene deposition generate significant production loss
and involve expensive corrective measures. The deposition of asphaltenes greatly reduces …

Asphaltene precipitation and its subsequent deposition is one of the major flow assurance
problems of oil industry. This issue could arise in upstream and downstream sectors. There …

Looking for efficient, environmentally-friendly, and low-cost demulsifiers for the separation of
oil–water emulsion is the goal of oil industry. In current work, natural lotus leaf was used as …

A three-branch structure demulsifier (GTE-DDA) for the treatment of water-in-crude oil (W/O)
emulsions was synthesized by a one-step method using glycerol triglycidyl ether (GTE) as …

Solid deposition during production, transport, and storage of crude oils leads to significant
technical problems and economic losses for the oil and gas industry. The thermodynamic …

Asphaltene deposition is a major problem during oil production and transportation that
imposes extra treatment costs and reduces oil production. Historically, various chemical …

A multi-branched trinuclear ionic liquid demulsifier (EDHBr-IL) was synthesized using
glycerol triglycidyl ether, di-n-hexylamine and 1-bromododecane as raw materials using a …

In this paper, extraheavy oil recovery assisted by CO 2 and an oil-soluble viscosity reducer
under deep reservoir conditions was experimentally investigated. Specifically, the viscosity …

Enhanced oil recovery (EOR) from carbonate reservoirs is of great challenge due to the
complex geology that originated from high rock heterogeneity and viscous fingering …

The development of eco-friendly, efficient, and economical demulsifiers for the
demulsification of water in crude oil emulsion is one of the important issues in the petroleum …
