..., a new coefficient is incorporated into the model to consider the impacts of the disconnected oil clusters during the cyclic injection. In addition, the end-of-cycle residual oil saturation (Som), which was required based on the Stone model, is no longer needed in this modified model. formulation...

... (water-oil) using both Darcy and Brinkman equations. Equations were discretized using a finite difference method (FDM) and solved using the IMPES formulation. The simulator was verified against representative cases of 1D and 2D reservoirs submitted to water injection. Results from both equations...

... for an analysis on both limit states in a single graphic. During studies of the Klever-Stewart and Klever-Tamano formulations it was verified that, despite both being combined models (the external/internal pressure and axial load influence the internal/external pressure resistance), the consideration...

...). Much higher concertation of surfactant than the optimally designed concentration in the EOR formulation has to be injected in order to account for the surfactant losses in the reservoir which often makes the whole EOR process uneconomical. Although extensive research has been performed with surfactants...

... formulations that cope with current technical and environmental requirements regarding emulsion prevention for oil exploration in Brazil. A series of studies has been conducted in order to better understand the effect of different parameters on the emulsion prevention of brines during completion operations...

... of application, a wide operating temperature range from -250 to 260°C (-420 to 500°F) and good chemical and abrasion resistance. With a variety of lubricant packages available to coating formulators, the PAI 1000 series grew to meet additional needs in new applications. Typical lubricant formulations by the PAI...

... Abstract Mixtures containing surfactants and polymers to be used in enhanced oil recovery operations should display special features: most notably low (or ultra-low) oil/water interfacial tensions and moderate viscosity. There is a variety of methods employed to assess formulations performance...

... attack. Due to the surfactancy of this class of chemistry, the tendency to induce and stabilize emulsions is of high concern. A robust formulation amenable to modification and potential dilution is required to address the application of chemical over a vast subsea network containing wells of varying age...
