Development and Performance of an Eco-Friendly Cross-Linked Polymer System for Water Shut-Off Technique

Excessive water production is a serious issue to be dealt with during oil production from reservoirs. The use of gel as the<br>water shutoff agent has been widely reported in enhanced oil recovery (EOR) for the development of mature oil fields.<br>Polymer gels are used successfully in many reservoirs all over the world, but the problem lies in finding the suitable and<br>economical polymer for the harsh reservoir conditions of high temperatures and salinity.
