    Industries developed during the last decades and the importance of oil is increasing. Petroleum is one of the most valuable non-renewable sources and it also, has the biggest effects on the environments after coal. Crude oil became the goal of many countries in order to increase their economies income, despite the outcome that has towards the environment. The crude oil that passes through the refinery process produces a large amount of waste, which is call petroleum sludge. The sludge has countless disadvantage that cause environmental hazards due to its remediation effects. In addition, it is very valuable energy and it can be recovered. So the companies used several methods in order to use this source and get benefit from it. One of the methods is the solvent extraction method and overall, this method can decrease the effect of the petroleum sludge on the environment but not that much. However, it can recover the waste and turn it to useful energy. The recovery can be done by different steps. The first step is making chemical compositions before using the instruments. Second step is to use the centrifuge machine which will separate the sludge and recover it into oil, sludge sediment and water. The third part is to use the residual carbon machine which will measure the solidcontent inside the sludge and it will help us to find the violate and non-violate hydrocarbons. Finally using the GC which is gas chromatography that checks the quality of the petrol and also the composition substance.

    Kurdistan is a new oil producing region in the Middle East, and the oil wells are located in or near farm-lands. Crude oil spillage is a big threat to the soil fertility, which is especially important for farming. Spillage occurs due to the pipeline rupture, and traffic accidents involving tankers which are very common in Kurdistan. The physico-chemical properties of soil are susceptible to alteration when polluted with crude oil, and this issue is not been studied well in Kurdistan. The intent of this paper is to study the effects of crude oil spillage on the physico-chemical properties of soil in Tarjan village, Kurdistan region-Iraq. For this purpose soil samples were collected in the Tarjan area, tested in a laboratory, and compared to non-polluted soil sample. The pH values of the soil samples remained almost the same. The electrical conductivity, and salinity increased. The amount of sulfate increased, the amount of potassium decreased. The amount of lead increased. The changes in these parameters in the soil affected plant growth in the spillage area, as there was no sign of vegetation on the affected soils. There was a positive correlation between salinity and lead and negative correlation between pH, electrical conductivity, potassium ions and sulphate ions.

    The present research paper is aimed at determining water and sediment contents in crude oil by using centrifuge method in laboratory in which ASTM D 4007-02 is used to analyze the samples. Furthermore, water and sediment contents in crude oil should be removed because for custody transfer process purchasers prefer to pay only for crude oil and want to minimize the quantity of water and sediment contents in crude oil. Presence of water and sediment contents in crude oil creates problems such as corrosion of equipment when dealt in oil industry along with the problem of oil viscosity. We examined sixteen samples. Four samples were taken from Guwayer oil site area and remaining four from Khurmalla oil site area. These samples were analyzed properly at MNR laboratory in Kurdistan Region-Iraq. The crude oils is considered as the best if it contains less water and sediment content and the vice versa is for the worst quality of crude oil .The method is easy and sharp to check the quantity of sediments and water in crude oil samples in lab and this quantity helps to tell the quality of crude oil

    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

    Fifteen crude oil samples were collected from different oil fields of the Kurdistan region, Northern Iraq to determine four trace metals, Fe, Ni, Cr and Pb. The analytical technique is applied mainly by flame atomic absorption spectrophotometry (ASS). Samples of these areas has not been previously examined for trace elements contents. API value of crude oils are inversely proportional to specific gravities and might be considered as a primary estimation for hydrocarbon contents. The relationship between trace metals and American Petroleum Institute (API) values of the samples are inversely proportional where the increasing API value of crude oil samples means a decrease in the metal contents of the samples. The method of dry ashing- acid dissolution (DA) was implemented.  The results concluded that crude oil samples of the Kurdistan region have a low metal content. Nevertheless, they could be seen as an essential health hazard for humans and the environment. In t-Test ˂  for iron, chromium and lead, there is no relationship between these three heavy metals.

    Heat shock proteins show remarkable variations in their expression levels under a variety of toxic conditions. A research span expanded over five decades has revealed their molecular characterization, gene regulation, expression patterns, vast similarity in diverse groups, and broad range of functional capabilities. Their functions include protection and tolerance against cytotoxic conditions through their molecular chaperoning activity, maintaining cytoskeleton stability, and assisting in cell signaling. However, their role as biomarkers for monitoring the environmental risk assessment is controversial due to a number of conflicting, validating, and nonvalidating reports. The current knowledge regarding the interpretation of HSPs expression levels has been discussed in the present review. The candidature of heat shock proteins as biomarkers of toxicity is thus far unreliable due to synergistic effects of toxicants and other environmental factors. The adoption of heat shock proteins as “suit of biomarkers in a set of organisms” requires further investigation
