Novel filtration process eliminates system upset following acid stimulation treatment
Recent changes in the environmental compliance rules and regulations regarding the overboard discharge of produced water have altered the way well stimulation fluid returns are processed. The flow back of treatment fluids, formerly handled under exception rules, was handled in a manner which normally minimized facility processing upsets. With the introduction of the new regulations, processing stimulation returns caused system upsets and has even halted production until the flow back treatment has been completely accomplished. The application of a filtration process used to avoid these problems in several acid flow back situations is presented. The filtration process equipment is described as well as operational considerations that may help eliminate facility upsets while maintaining environmental compliance. Discussion of the additive packages tested for pre-job oil emulsion and water oil and grease screening is included. Fluid analysis of the flow streams into and out of the filtration process and cost for four case histories are summarized.
