Dear Ms, As you may be well aware, RIPI (Research institute of Petroleum Industry) is a subsidiary of National Iranian Oil company (NIOC). In Polymer Research center which is affiliated to RIPI, we have recently started working on using gel polymers based on poly acrylamide to reduce the mobility of water in oil producing wells. We are very interested in applying appropriate gels in some Iranian oil reservoirs with high temperature about(90 C) and high salinity ( 250,000 ppm). We would be grateful if you would inform us whether you could supply1000kg anionic partially hydrolized polyacrylamid,1000kg cloisite and 500 kg chromium acetate.If you could supply any of these items please let us know their specification and their prices. Best regards Dr j.Alaie
