Determination of the Total Sulphur Content in Khurmala and Guwayar Oil Fields of Kurdistan Region, Iraq

Five different samples of crude oil were evaluated. Three samples are from Khurmala crude oil field, and two samples are from the Guwayer crude oil field. All samples were evaluated to distinguish between qualities of both fields which are important sources of crude oil in the Kurdish Region. The specific gravity, API gravity, and the sulphur content were measured for all samples. Energy Dispersive X-Ray Fluorescence (EDXRF) was used to determine total sulfur content, a hydrometer was used to measure specific gravity and by using a mathematical equation we can find API gravity. By estimating these three parameters, crude oil of both fields were evaluated. In the samples of Guwayar oil field that measured the total sulfur in one of the well is 0.607 %(mean) wt and in second well was 0.6905 % wt(mean), while the total sulphur content in samples of three wells in Khurmala oil field were 2.3324% wt(mean), 2.1016% wt(mean), and 0.7362% wt(mean). We are 95% confident that there is no significant difference and we rejected the null hypothesis. There is strong relationship between sulphur content wt. % and specific gravity of the samples
