Formulation Development of High Strength Gel System and Evaluation on Profile Control Performance for High Salinity and Low Permeability Fractured Reservoir
For the large pores and cracks of reservoirs with low temperatures, high salinity, and low permeability, a new type of high strength gel ABP system is developed in this paper. The defects of conventional gels such as weak gel strength, no gelling, and easy dehydration are overcome under the conditions of low temperature and high salinity. The temperature and salt resistance, plugging characteri...
متن کاملPreformed Particle Gel for Conformance Control
Preformed particle gel (PPG, a kind of Super Absorbent Polymer) has been successfully applied to control conformance in around 2,000 wells in China oilfield. The paper summarizes: (1) why we proposed the method, (2) What are the properties of thermalstable PPG products, (3) where it has been used and how to select a good well candidate for a PPG treatment, (4) how to improve PPG treatment resul...
متن کاملApplication of Decline Analysis in Fractured Reservoirs, Field Case Studies
Decline curve analysis has some advantages over transient well test analysis in which it is not required to shut-in the well and also wellbore storage effects do not exist. Few studies have been done on decline curve analysis of naturally fractured reservoirs but there are even some limitations with available models. On the other hand well test could be expensive and in some operational conditi...
متن کاملGel performance in rheology and profile control under low-frequency vibration: coupling application of physical and chemical EOR techniques
Flowing gel plugging and low-frequency vibration oil extraction technology have been widely applied in low-permeability formation. High probability of overlapping in action spheres of two technologies might lead to poor operating efficiency during gel injection. Study on flowing gel rheological properties under low-frequency vibration was essential, which was carried out indoor with viscosity m...
متن کاملNumerical Modeling of Boiling Due to Production in a Fractured Reservoir and Its Field Application
Numerical simulations were carried out to characterize the behaviors of fractured reservoirs under production which causes in-situ boiling. A radial flow model with a single production well, and a two-dimensional geothermal reservoir model with several production and injection wells were used to study the two-phase reservoir behavior. The behavior can be characterized mainly by the parameters s...
