Produced water isolated from the oil in oil-gas production is pumped into the injection wells after cleaning from salt deposits and mechanical impurities. In the mixture of high-mineralised produced water, salt deposits making the technological equipment and pipes useless while gathering and transportation, reduce the permeability of injection wells. Carried out experimental researches show that for each ton it is necessary to pump 100 g of KD-7 inhibitor to prevent salt deposition in the mixture of produced water. Technological processes should be performed in a closed system, and the territories contaminated with oil and produced water cleaned and equipped well.

ABSTRACT The ability of some halophytes to accumulate salts may make them helpful in remediating soil contaminated with produced water and drilling mud from oil and gas exploration and production. Three inland halophytes, Atriplex acanthocarpa (two accessions) and A. canescens, were grown in pot culture in salt-contaminated soil, soil contaminated with salt and hydrocarbons, and uncontaminated soil collected from a Webb Co., Texas, gas production site. Electrical conductivity and soluble sodium of the soil extract were determined prior to planting and re-analyzed following harvest. Total sodium content in mature leaves was determined following harvest. Mature plant survival for all species in all soils ranged from 90–100%. In the salt-contaminated soil, post-harvest electrical conductivity and soluble sodium were significantly lower in the planted soils than in the unplanted soil. For each accession, biomass and plant mortality were greatest in the salt-contaminated soil. In both contaminated soils, the local ecotype of A. acanthocarpa had the highest concentration of tissue sodium and produced the greatest decrease in both electrical conductivity and soluble sodium. Field studies are necessary to determine the effectiveness of in situ application.

This paper presents a case study of a natural gas production site covering various technical issues related to selection of an appropriate Reverse Osmosis (RO) system. The long-term field experience indicates the necessity of the selection of appropriate pretreatment systems for fouling-free RO operational conditions. The produced water has a variety of impurities such as oil and grease, process chemicals used for corrosion and scaling control, and dehydration of natural gas, etc. This situation leads to a complicated and extremely difficult task for a membrane specialist to design RO systems, especially the pre-treatment section. Here as part of the pretreatment selection, two types of UF membrane modules viz. spiral wound and hollow fibre, with MWCO of 8000 and 50,000 Dalton respectively, were tested in parallel with NF membranes of the spiral wound type with MWCO 200 Dalton. The UF permeate is used as feed for RO compatibility testing. Both configurations of UF failed to be compatible, due to irreversible fouling of the RO membrane. The NF membrane, however, showed interesting results, due to membrane stability in terms of cleaning and fouling. The NF plant with 50% capacity gave a recovery of 75% and the RO plant gave a recovery of 60% versus the expected 92–95%. The long-term tests have indicated that the reminder of the membranes could be installed to achieve full capacity of the plant. This study also demonstrates the importance of selection of proper pre-treatment set-up for the RO system design.
