Abstract Injection of blocking gels in the near wellbore of producer wells is a technique employed for water production control. A proven and effective alternative to control this water excess is the application of crosslinked gels.
Water shut-off (WSO) treatments efficiency depends on several aspects such as reservoir fluid flow patterns, rock petrophysics, formation heterogeneities and gel characteristics. Although experimental laboratory tests previous field implementation, are many times underestimated, they provide valuable information that increases the chances of success. Integrating lab results with reservoir and field data creates a proper scenario that diminishes the uncertainties during field implementation. It is also crucial the support of a multidisciplinary team work while injecting the WSO tretament.
This paper presents a successful water shut-off treatment specially designed for high temperature, applied in a production well located in Vizcacheras field, Mendoza Agentina.
