Effect of Fe (III) and Chelating Agents on Performance of New VES-Based Acid Solution in High-Temperature Wells
(2017-04-26)Viscoelastic surfactant (VES)-based acid systems are used in acid-diversion applications. However, high-temperature, interaction of the VES and Fe(III) (as a contaminant), addition of alcohol-based additives, and chelating ... -
Impact of Nanoparticle Shape on VES Performance for High Temperature Applications
(2018-12-03)Viscoelastic surfactants were introduced in hydraulic fracturing fluids as a proppant carrier in order to replace polymers which possess high potential for formation damage. Yet, VES technology is limited by its low thermal ... -
Rheological Study of a Novel Sulfobetaine Surfactant-Based Acid System
(2015-11-13)Acid stimulation is a widely used well treatment technique applied to enhance oil production by creating conductive channels through the formation, resulting an improved flow property. Viscoelastic surfactant (VES)-based ... -
The Impact of Pore Structure on Carbonate Stimulation Treatment Using VES-Based HCl
(2016-07-28)Regular HCl has been used for years in carbonate stimulation treatment because it reacts rapidly with carbonate rocks. However, due to fast reaction, the acid reacts near the wellbore area and is not able to travel deeper ... -
Well Productivity Enhancement of High Temperature Heterogeneous Carbonate Reservoirs
(2014-05-08)Acidizing is one of the most popular techniques for well productivity enhancement during oil and gas production. However, the treatment method is not very effective when the wellbore penetrates through multiple layers of ...
