The prospect of oil production from the Arctic region is attracting attention as the world is becoming more aware about the end of cheap and easy oil. The security and economic risks associated with the expensive and difficult oil remains very high. In deep-water projects, thousands of feet below the sea level, temperatures are near freezing. Combined with the high pressures present at these depths, oil congealment and ice-like hydrate formation is a commonly occurring phenomenon which results into flow restriction. This in turn leads to various production problems and hence substantial financial loss. To counter these problems, Soya slurry is proposed as an anti oil-congealer in this paper.

The soybean slurry consists of chemicals like Glycoprotein and unsaturated fats, which act as an anti freeze and suppresses ice nucleation effect. It is introduced in low concentration into the well bore which prevents the well bore fluid from congealing by increasing its thermal hysteresis and acting as an ice nucleation barrier. Even the viscosity of the wellbore fluid substantially reduces resulting in an easy and smooth flow through the pipeline with very less amount of friction experienced between the fluid and tubing.

Based on a detailed study, we have inferred that as soybeans are easy available, they have low cost and require simple application techniques, therefore they can provide an appropriate solution to the oil congealment problem.

This study will provide fresh physical insight into the phenomenon of anti oil congealer and help in countering the congealment problem in a more effective, economical and environment friendly way.
