Due to the above-mentioned they are volumes feasible considerable remainders of recovering by means of well-known techniques as of improved recovery (Tertiary...

... On the basis of laboratory studies, the pilot test with high concentration polymer solution was conducted in SaZhong area, Daqing Oilfield in August of 2002 to prove the field application results by high concentration polymer flood. Six injection wells, scattered in commercial polymer flood...

.... The goal of cost reduction, which is a major objective in any recovery methods, can be met by using MEOR technology which involves injecting a small amount of a solution containing microorganisms to spread through the reservoir and consequently produce desirable chemicals and gases that will enhance oil...

The program adjusts was carried out in three phases: Injection proposal, Test...

... was provided when the wetting preference between the injected fluid and the rock surface allowed the formation of stable wetting phase bridges. The combination of high spatial resolution imaging and rapid data acquisition revealed how the transport mechanisms for oil and water were governed by the wetting...

... pressure test, and was placed back on injection. This was the first time in a BP operated waterflood that a DGLV had been identified as the source of tubing to "A" annulus communication in an injector. Prior to obtaining the ultrasonic log results, it was generally believed that slow tubing...

This paper describes the outcome of pressure analysis successfully used for Cuttings Re-Injection (CRI) and disposal of produced water resulting from closely monitoring pressure injection and decline. It addresses proper root-cause...

... to enhance oil recovery processes. The goal of this paper is to investigate the profitability of immiscible water alternating CO 2 injection in the secondary and tertiary recovery after water-flooding and continuous CO 2 injection at laboratory scale. The experiments were performed in the sand packed...

... Abstract Waterflooding for enhanced oil recovery requires that injected waters be chemically compatible with connate reservoir waters, in order to avoid mineral dissolution-and-precipitation cycles that could seriously degrade formation permeability and injectivity. Formation plugging...

... Abstract In-situ combustion is a thermal recovery method used for enhanced heavy oil recovery. In this process air is injected to the reservoir in order to achieve ignition and to maintain the combustion front while pushing the heated oil toward producing wells. This study deals...

... of the surface facilities necessary to collect, process and inject seawater. The third objective consisted of investigating the technical feasibility for miscible gas flooding into an equally tight reservoir, together with the facilities to collect and inject the gas. Both injection projects required...

... Abstract During the last 15 years, polymer gels have become an accepted technology for improving volumetric sweep efficiency in heterogeneous waterfloods. Water injected subsequent to the gel treatment ideally enters previously unswept zones with significant mobile oil saturation. Results from...
