This paper presents a case history of successful acid stimulation treatments on acid sensitive crude producers in the Gulf of Mexico at Main Pass 313 field. It shows how catastrophic emulsion and facility upset problems encountered during the flowback of the first well in a multi-well stimulation program were resolved and used as the basis for optimizing treatment design on the remaining wells. Overall, it demonstrates how taking a preventative posture through a total system approach to the stimulation process was the key to solving the acid treatment flowback problems experienced.
