Abstract
  Oil recovery from oil wet carbonate rock is a big challenge in oil industry. In the present study, the influence of natural surfactant Hawthorn leaves extract (HLE) on oil recovery from carbonate rock is investigated. Two chemical surfactants include Sodium dodecyl sulfate (SDS) and Dodecyl tri methyl ...  Read More

Abstract
  One of the tertiary methods for enhanced oil recovery (EOR) is the injection of chemicals into oil reservoirs, and surface active agents (surfactants) are among the most used chemicals. Surfactants lead to increased oil production by decreasing interfacial tension (IFT) between oil and the injected water ...  Read More

Abstract
  As a physiochemical property, asphaltenes are known to be one the most surface active compounds in crude oil. Due to such property, their behavior is most probably influenced by fluid-fluid interactions at the contact surface (interface). Potentially and naturally, in most cases, water is in contact ...  Read More
