    INTRODUCTION OF COTTON GUM AS A NATURAL POLYMER TO ENHANCED OIL RECOVERY
    (جامعة الوادي - university of el oued, 2015) Arjmand, O; Zarekhafri, A
    Polymer flooding as an enhanced oil recovery (EOR) method is widely utilized to improve water flooding and plays an important role during EOR process. Partial hydrolyzed poly acryl amide (HPAM) as one of the well known polymers is used in order to have a decrease water/oil mobility ratio in oil reservoirs. As this polymer is decomposed at reservoirs having high temperature and high salinity, the use of this polymer is limited. This study introduces cotton gum as a new natural polymer which can be used for polymer flooding. Cotton gum as a polysaccharide is obtained from the natural cottons. To compare this polymer with HPAM, related experiments including thermal decomposition and viscosity tests in same conditions were conducted and our experiments confirm that this polymer shows a good resistance against high salinities and temperatures

    AN OVERVIEW OF THE POLYMER GEL TECHNIQUE TO IMPROVE THE EFFICIENCY OF WATER FLOODING INTO OIL RESERVOIRS (WITH INTRODUCTION OF A NEW POLYMER)
    (جامعة الوادي - university of el oued, 2013) Arjmand, O; Ahmadi, M; Hosseini, L
    An important property of polymer gels is that the injected fluid in the fracture area with high permeability moves and can form a solid mass, in result of water and gas permeability because of the formation of this layer will be decreased. In gel polymer techniques first amount of the polymer solution is injected into the reservoir with a low rate, then the cross link solution such as aluminum or magnesium citrate is injected into the reservoir and gel to be figured. Therefore, improves oil recovery and reduces the percent of water production. This study concerns a light review on gel polymer process and this study introduces a new polymer with superior flooding property to water shut - off, too
