NEW ADSORPTION MEDIA TECHNOLOGY MEETS WATER-TREATMENT CHALLENGES

Journal of Petroleum Technology 70(6):(2018)

The performance of Osorb with live fluids was evaluated during a technology demonstration in Oman in collaboration with Petroleum Development Oman and Qatar Petroleum. An automated pilot OMS was placed inside the Marmul Water Treatment Plant to treat water from a CEOR operation using polymer to increase oil recovery. The system was placed downstream of the free-water knockout and upstream of the primary water treatment system which consisted of induced gas flotation vessels and nutshell filters. The goal of the demonstration was to reduce the OIW to less than 5 mg/L using only the OMS. The field trial was split into two phases, differing in the method of regeneration. A total of 4,300 bbl of produced water were treated by the OMS with eight regenerations. The inlet OIW averaged 59 mg/L and fluctuated from 12-202 mg/L over the eight cycles, while the outlet OIW averaged less than 1 mg/L. The media maintained greater than 90% oil removal efficiency after each regeneration cycle. https://www.spe.org/en/jpt/jpt-article-detail/?art=4193
