Solving asphaltene precipitation issue in vertical wells via redesigning of production facilities

Petroleum, 2015
Precipitation of heavy hydrocarbon components such as Wax and Asphaltenes are one of the most challenging issues in oil production processes. The associated complications extend from the reservoir to refineries and petrochemical plants.

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

Influence of asphaltene precipitation on development effect of typical heavy oil reservoirs in eastern South China Sea

Youqi dizhi yu caishoulu
During the development of heavy oil reservoirs in the eastern South China Sea， asphaltene precipitation can cause blockages in reservoir throats， wellbores， and pipelines， leading to a decrease in the productivity of oil wells.

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

Deep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

EFFECT OF INHIBITORS ON ASPHALTENE PRECIPITATION [PDF]

, 2013
Asphaltene precipitation and its deposition along the production system and separation facilities cause a lot of problems in the Oil and Gas industry. It damages reservoir by reducing its permeability while also changing its wettability.

Rapid Heterogeneous Asphaltene Precipitation with Dispersed Solids

, 2018
Inorganic solids are often present in real heavy oil systems, but are typically absent in asphaltene laboratory studies. For the first time, we investigate the influence of inorganic solids on the kinetic precipitation of asphaltenes.

Effect of Asphaltenes and Asphaltene Dispersants on Wax Precipitation and Treatment

Colloids and Interfaces
A detailed understanding of the interactions between wax and asphaltenes with other components of crude oils and the effect of treatments with paraffin inhibitors (PIs) and asphaltene dispersants (ADs), with a focus on identifying specific structure-activity relationships, is necessary to develop effective flow assurance strategies.

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,
