Abstract

The effect of reversible invert emulsion drilling fluid additives on the soil has been examined in order to evaluate their toxicity and possible environmental impacts that may result from their indiscriminate disposal. Development of effective policies for discharges depends on consideration of the specific local environmental conditions that govern the fate of discharge materials, the scientific basis for assessing the potential for effects in that environment, and balanced consideration of the environmental effects and relative costs of discharge versus other disposal options. This paper reviews the framework that will help achieve general regulatory acceptance of the discharge of reversible invert emulsion mud. In this study, the contaminated soil samples were collected and analysed for metals (iron, copper, zinc, lead, nickel, chromium, manganese, calcium and magnesium) using Atomic Absorption Spectrophotometry (AAS) method. The results showed that Calcium (Ca) has the highest concentration followed by Iron (Fe), Copper (Cu) with varying level of toxic metals like lead (Pb), Nickel (Ni), Manganese (Mn) and Chromium (Cr) in the soil sample. Metals like Fe, Mn and Cu generally have values higher than that of the United States Environmental Protection Agency and World Health Organization Standards thereby implying possible negative impacts on the immediate environments. It is therefore recommended that wastes resulting from oil cuttings and drilling muds should be properly treated before it is disposed into the environment by oil exploration companies.
