With increasingly stringent environmental limitations on the disposal of treated produced water in offshore operations, it has become even more important to gain a better understanding of the process upsets which contribute to poor disposal water quality. One such process upset is caused by the handling of the non-produced fluids (fluids resulting from well stimulation or remedial operations and from miscellaneous processes such as deck drainage) in water treatment equipment (e.g. flotation cells, hydrocyclones etc.). This paper discusses the results of the field tests with various chemicals, normally present in non-produced fluids, on the performance of a bench model flotation cell. These results are not limited to flotation cells but are also applicable to other water treating equipment such as hydrocyclones. An approach to minimize the impact of the non-produced fluids on produced water treatment equipment efficiency is presented in the paper.
