Oil and gas production from the reservoirs are often accompanied by huge amount of water production which is the major problem faced in petroleum industry worldwide. Polymer gels have been successfully used for many years to control water production. Most methods involve crosslinking of partially hydrolyzed polyacrylamide- PHPA using organic or metallic crosslinkers. These polymer gels are formed in-situ under the reservoir condition which blocks the water producing zones thereby reducing the water production. This paper attempts to for the selection of suitable polymer and crosslinker concentration for Gandhar field in Cambay basin using gel study and core flooding analysis. Polymer is made gel using organic crosslinkers at stable reservoir temperature 90°C. https://www.biotech-asia.org/vol11_nospl_edn1/water-control-analysis-on-production-enhancement-along-with-permeability-modification-by-polymers/ Water control; Permeability; polymers
