... viscosity, gel and foam's plugging effect, surfactant reducing oil-water interfacial tension. Meanwhile, through numerical simulation the thermal and chemical mechanism was characterized by relative permeability interpolation method with experimental results taking into account. The above research shows...

..., the operator had to spot various LCM pills along with facing various stuck-pipe incidents in most of the offset wells, resulting in the revision of the casing program. This study assesses the use of multiphase-foam drilling to penetrate the fractured Kirthar and Laki limestone, offering lost circulation...

... ABSTRACT A comprehensive series of experiments on foaming of two (2) types of crude oil and four (4) types of synthesized Gemini silicone- amine base defoamer in simulated produced water system containing foam surfactant Foam Assisted-Water Alternating Gas (FAWAG) package were investigated...

... in shale remains unclear, particularly with regard to the choice of type of fracturing fluid during fracturing operation at high confinement. Hydraulic fracturing with supercritical carbon dioxide (SC CO 2 ) and SC CO 2 foam are an encouraging technique to overcome significant use of water in shale gas...

... In order to generate robust and effective foams, surfactants with amphiphilic structure are added which serve as foaming agents. Although these surfactants have been developed over the years, few surfactants are available that can resist the harsh conditions of salinity and temperature. Among...

... Abstract The paper discussed the development of an Ultra-Low Interfacial Tension (IFT) foaming surfactant based on a combination of improved as-synthesized surfactant (CBH) consist of as-synthesized oleic amido propyl betaine with mixtures of co-solvents and PETRONAS’ in-house patented foaming...

... Abstract During field recovery optimization, EOR takes a role to keep active and always develop the techniques for increasing oil production from time to time. Foam flooding has been introduced as a new technique to overcome the limitation of gas injection by reducing gas mobility. Specifically...

... Abstract The use of foams is a promising technique to overcome gas mobility challenges in petroleum reservoirs. Foam reduces the gas mobility by increasing the gas apparent viscosity and reducing its relative permeability. A major challenge facing foam application in reservoirs is its long-term...

... Abstract Foam Assisted Water-Alternating-Gas (FAWAG) flooding is one of the enhanced oil recovery (EOR) technique that had been explored and studied worldwide. The ability of foam to lower the gravity override and create a macroscopic sweeping of oil in the reservoir shows its potential...

... This paper investigates the effect of rock permeability on foam transport in porous media both at the core-level and at the field level for enhanced oil recovery (EOR) applications. Foam offers promise to simultaneously address the issues that limit the overall oil recovery efficiency of water...

... Abstract Conventional technologies used for insulation of flowlines in shallow-water fields, based on thermoplastic foams, are over-specified for the conditions. This has driven development of a low-cost alternative based on a low-density polyurethane thermoset foam. This paper will trace...

... of foam assisted WAG (FAWAG) limitations such as foam callapse and short propagation distances, Blaker T. et al (1999), Skauge A. et al (2002) and Aarra M.G. et al (2002) from Snorre field pilot experience. This process is called as an in-situ-FAWAG or icFAWAG and discussion focus is on 1D coreflood...
