“…Several organic and inorganic components present in produced water can be potentially or more hazardous than the crude oil itself [9]. Organic pollutants can destruct the environment and constitute a health risk to man and the ecosystem [10].…”

“…There was evident change in weight of earthworms during the test across all PFW preparations, and weight can be said to be a more sensitive parameter than survival in accessing pollutant effect in soils ATUANYA, E. I; ISERHIENRHIEN, G. O; EMEJULU, M. J earlier reported by Udochukwu et al (2017). Gazali (2017) reported that the organic and inorganic compounds in produced water have higher toxicity compared to that of crude oil, and the discharge of these toxicity compared to that of crude oil, and the discharge of these toxic constituents and contaminants to the aquatic life and agricultural resources by altering the natural state of the aquatic environment. It is necessary to treat produced water before discharge to avoid the harmful effects that the chemicals in the waste waters may have on the receiving environment.…”

The research work was carried out to investigate the effects of produced formation water on soil nitrifying bacteria and earthworm using standard methods. The microbial analysis of produced formation water samples showed the presence of Pseudomonas aeruginosa, Bacillus cereus, Micrococcus luteus and Yeast and Aspergillus niger. Physicochemical parameters of produced formation water (PFW) analysed shows neutral pH (6.33), high electrical conductivity (960.6 S/cm), lower than accepted temperature (28.46oC), total dissolved solids (TDS) (756mg/l), dissolved oxygen of 4.6mg/l and higher than accepted of nitrate (52.mg/l), sulphate, lead, chromium, cadmium and copper. The PFW treatment was observed to increase nitrate content and optical density of receiving soil. The treatment progressively decreased the Nitrobacter count across the experimental duration period (seven days) and decreased earthworm survival as the % treatment increases. This study revealed that produced formation water negatively impacts the receiving soil and its organisms in several ways. Hence, regulatory bodies could strengthen its sensitization to the public and private enterprises and the general populace on the damage of discharge of produced formation water.

“…FW contains a high amount of sodium, and its conductivity is not suitable for irrigation purposes. In addition, the presence of radioactive elements (226 Ra, potassium isotope, 137 Ba, 210 Po, 212 Bi, 214 Bi, 208 Ti, lead isotopes 214 Pb and 210 Pb) in the effluent can degrade the soil and groundwater quality. − These observations indicate that FW requires proper treatment before its disposal. FW may be allowed to dispose of (onshore and/or offshore) or reinjected into the abandoned wells only below the ground level (>1000 m) once it complies with the prescribed environmental norms.…”

Recent Perspectives on the Management of Formation Water Generated from Hydrocarbon Reservoirs

The water associated with oil and gas reservoirs is formation water (FW), which is generated at the surface during hydrocarbon production. The major challenges associated with the treatment of FW are higher contents of oil and grease, high salinity, suspended solids, organic pollutants, traces of heavy metals, and undesired microbes. To meet the stringent requirements for the usage and disposal of FW, various treatment methods have been developed and implemented in the oil industries for the sustainable management of generated FW from the hydrocarbon reservoir. This article aims to summarize the aspects related to the treatment of FW like the generation, available treatment methods, and prevailing challenges. The basics and working principles of individual methods have been described along with relevant examples for the treatment of FW. In addition, the combined/hybrid methods for the treatment of FW have also been discussed to improve overall efficiency. Hybrid methods have shown a better performance than conventional techniques and need to be implemented for effective treatment of the voluminous FW to meet stringent environmental standards for reuse and discharge.
