Abstract: The oil yield, fatty acid composition and the physicochemical and quality characteristics of Tamarindus indica Linn seed oils obtained by solvent extraction were determined. Effect of various solvent and solvent combinations on the extraction of T. indica seed oil showed that ethanol as an alternative solvent to have better yield with 8%. Optimized process conditions were solid to ethanol ratio of 1:6w/v, under reflux for 6h and agitation speed 100rpm. Extracted oil analyzed by Gas Chromatography-Mass spectroscopy. T. indica oil was tested for its physical and chemical properties including percentage of fatty acid, kinematic viscosity, saponification value, unsaponifiable matter. The stability of T. indica oil during storage at room temperature and during heat treatment was studied. Result of the present research indicates that ethanol can be a better alternative to other solvents. Also indicate that the T. indica seed oil can be used as a potential alternative to nutritional food.

Abstract: High concentrations of H2S and CO2 make oil producing wells highly corrosive to normal steels alloys, such as carbon steel. The usual solution to this is high chrome steels alloys, such as ferritic stainless steel, i.e. 13Cr. These steels have a good service record in such environments, especially at operating temperatures below 150°C. However the passive film which provides protection can be easily damaged by mechanical activities such as wirelining. The lack of repassivation in these environments means that once damaged by mechanical action these tubulars suffer extensive localized corrosion. A comparison is made of the different workover methods which can exacerbate this problem, particularly wirelining. Where possible we recommend the use of coiled tubing.
