Abstract

The oil and gas industry is exposed to fow assurance issues such as wax deposition and scale precipitation. The sector has been tackling this issue using the chemical method while extensive research is being conducted to fnd an efective solution. The conventional method is costly and not eco-friendly. This paper focuses on using Jatropha curcas seed oil (JSO) blended with Ethylenediaminetetraacetic acid (EDTA) as a promising dual inhibition application solution to counter wax and scale deposition simultaneously. The experiment manipulates the temperature and concentration to determine the efciency of the inhibitor and its capability to improve fowability. Flowability and jar tests were conducted to analyze the blend’s ability to act as a dual inhibitor. The results prove that the blend of JSO and EDTA at the concentrations of 3 wt% and 1 wt%, respectively, at 70°C showcased a robust result in wax inhibition by enhancing the fowability of the crude oil. On the other hand, efective scale inhibition is achieved when 1 wt% JSO is blended with 1 wt% of EDTA at 27°C. The results obtained signifes the compatibility of JSO and EDTA blend in dual inhibition application when optimal temperature and concentration are achieved. Dual inhibition application is expected to be a one-stop solution for both wax and scale precipitation that is economically viable and safe.
