Black Oil Leakage Influence on the Physical and Engineering Properties of Faw Soil

Abstract

Various regions of the world experience oil pollution for many reasons, including oil spills due to transport accidents or during oil exploration. These oil spills will have a negative impact on the environment and can change the geotechnical properties of the soil. The soil in Faw city, in the southeast of Basra Governorate, is frequently polluted due to the presence of many pipes and wells; oil leakage has been encountered as a result of damage to these pipes. The aim of this article is to study the effects of black oil on the physical and engineering characteristics of Faw soil. The analyses include two parts: (a) Natural soil properties and (b) Contaminated soil properties with oil percentages of 2.0, 5.0, 10.0, 15.0, and 20.0 % of the weight of the dry samples. Various tests were carried out. The results show an increase in soil compressibility and reduction in permeability due to the addition of black oil. In addition, the results show that using a layer of soil-oil-water under the foundation is advisable. This layer must be isolated from living creatures.

“…[11] maintained that the lubricating effect of crude oil led to the decrease in the optimum moisture content (OMC) and an increase in the maximum dry density (MDD) of crude oil contaminated alluvial soil. An increase in the compressibility and a decrease in permeability of Faw soil was reported by [12] when contaminated with black oil. The unconfined compressive strength increases with up to 10% oil content before decreasing at higher percentages.…”
