Abstract : Scale formation in oil wells is one of the most common problems confronting oil and gas industries around the world. Although great technologies have been developed by engineers to combat scale formation, yet the problem remains without an effective solution. Scale deposition problems have been managed by injecting scale inhibiting chemicals into the area of interest to inhibit the formation of scale. However, the cost and environmental concerns of available scale inhibitors continue to increase the interest of researchers to develop better and cheaper alternative to the available ones. This informed the interest in sweet orange mesocarp extract (SOMEX), a locally abundant renewable source as possible raw material for oilfield scale inhibitors. Rutin obtained from SOMEX was modified using furfuraldehyde, and urea at varying molar ratios to form a novel green scale inhibitors, namely, Rutin (RU), Rutin-Furfural-modified polyphenolic resin (FRU) and RutinFurfuraldehyde-Urea- modified polyphenolic resin (URU).

Keywords : Sweet Orange Mesocarp Extract (SOMEX), Rutin (RU), FRU, URU, Commercial Inhibitor (CSI), Calcium Sulphate Scale (CaSO4).
