Paper presented at the SPE Kingdom of Saudi Arabia Annual Technical Symposium and Exhibition, April 23–26, 2018
Paper Number: SPE-192322-MS
.... Viscoelastic surfactants are introduced because of their dual capability of lowering the IFT and improving the sweep efficiency of the reservoir. In this paper, the main objective is to determine ultralow IFT's and thermal stability that can be obtained from viscoelastic surfactants in the presence of heavy...

... would divert into previously uncontacted layers to improve sweep efficiency. The potential of the proposed CIM in improving oil recovery is demonstrated by various simulations of reservoir cases under waterflooding. We performed various sensitivities to investigate the effectiveness of the proposed...

Paper presented at the SPE Kingdom of Saudi Arabia Annual Technical Symposium and Exhibition, April 23–26, 2018
Paper Number: SPE-192379-MS
... Abstract Due to the strong mobility and energizing effect, CO 2 can be injected into reservoir as a displacement agent to increase oil production in low permeability reservoir. However, low viscosity of pure supercritical CO 2 (SC-CO 2 ) resulted poor sweep efficiency. Therefore...

... pressure is not exceeded. The presence of TIFs severely distorts the flood front, decreasing sweep efficiency. This paper applies several published, waterflood analysis methods to TIF characterization in synthetic and real case studies. These methods include well injection history data using modified Hall...

Paper presented at the SPE Kingdom of Saudi Arabia Annual Technical Symposium and Exhibition, April 24–27, 2017
Paper Number: SPE-188023-MS
... Abstract The oil recovery from fractured reservoirs is usually low, which is usually caused by the existence of areal formation heterogeneity. Preformed particle gel PPG has been used successfully use to reduce Heterogeneity and improve sweep efficiency. Low salinity waterflooding (LSWF...

... and temperature. These conditions make most of the conventional surfactants and polymers ineffective. Fractures in carbonate reservoir provide the easy conduit for injected slugs to break through the production wells, thereby reducing the sweep efficiency drastically. Thus the carbonate reservoirs...

... and/or chemicals in the formation such as polymer, acids, gases and surfactants. Production of these chemicals in the formation changes fluid and rock properties of the reservoir and improves the sweep efficiency. This change respectively increases the oil production from the reservoir. This paper presents...
