Abstract

The petroleum accumulations are found associated with water and it is rarely obtained without accompanying water production. Water production is a major technical, environmental, and economic challenge associated with oil and gas extraction. Rheological findings are of fundamental importance for the development, manufacture and processing of innumerable products. Polymeric gels exhibit a wide range of rheological properties and they are stable both mechanically and thermally in most cases thus are suitable for a variety of applications including controlled drug recovery, soft contact lenses and gelatin foods. The flow curves of different polymer gelants at different concentrations have been presented at different temperatures. In this study, the increment of gelant solution viscosity during gelling reaction was considered as an indication of development of gelation kinetic. Thus, a thorough knowledge of the viscosity changes with gelation is important for obtaining better results in the field. The data obtained from rheological study helps to roughly analyze the gelation time which can be determined from the viscosity buildup of the gelant. Thus, this is an indirect method to determine the gelation time which is an important characteristic of the polymer gel system. investigation on the bulk gelation studies and the effect of different parameters such as temperature, salinity, pH, concentration of polymer and cross-linkers on the gelation time and the thermal stability of the modified gel system in bulk. Gelation time is one of the most important characteristics of a polymer system which helps to determine the depth up to which the gelant can flow before gelation because if gelation occurs before reaching the target zones than the purpose of using the gel will remain unfulfilled.

Keywords: Polymer gelation, rheological properties, water production control, gelation time, thermal stability, cross-linking agents, enhanced oil recovery
