... Abstract The paper demonstrates a water shutoff technology in naturally fractured reservoir, which is based on simultaneous placement of a polymer gel and foam in fracture, where foam is stabilized by delayed formed gel. Lab studies were undertaken to develop a gelled foam formulation...

... expansion can load the pipe material beyond its proportional limit. Selection of an appropriate slotted liner configuration is critical to ensure structural stability (and hence sand control) is reliably maintained during operation. Mechanical properties of the tubular material at elevated temperature...

... Abstract The performance of the THAI ™ process has been investigated in numerous 3D experiments, using heavy crudes and Athabasca Oil Sands bitumen. The stability of the process is demonstrated by high combustion zone temperatures, absence of gas channelling, insensitivity to large changes...

..., and pressure on the stability and size of the microbubbles needs to be better understood in order to design a fluid that will sufficiently block the pores of the formation for extended periods. In this study, effects of time, pressure and temperature on the size of the microbubbles and the stability...

...) . Under VB conditions, residues are simultaneously disproportioned into low molecular weight (MW) distillates and hydrogen deficient bottoms. Further insoluble coke is generated when the process is carried out to higher severities (2,3) . VB yield is constrained by the stability of the product. Under...

..., it is necessary to determine the properties of the interfacial film that contributes to their stability. In many cases and, in particular with heavy oils, this film is believed to consist of surface-active materials such as resins, asphaltenes, and native solids. This work focuses on asphaltenes and their role...

... on the stability of zirconium crosslinked gelled hydrochloric acid viscosity is presented. In addition, the crosslink delay effect on ultimate viscosity is presented. Background Stimulation of carbonate reservoirs is typically the result of a need for restoration or enhancement of production to a more economic...

... oil might play in the performance of gel. Performance and stability of above gel systems for reducing the permeability of the carbonate medium to the injected water and carbon dioxide was tested in a series of flow experiments by alternatively injecting several pore volumes of water and carbon dioxide...

... in the presence of oil or in intermediate to oil-wet media (2) . Petroleum reservoirs can exhibit a wide range of wettability from water-wet to oil wet. Therefore, it is of considerable interest to understand how rock wettability influences foam stability and performance (3) . Currently, the limited...

... of the filtrate in the formation. On the other hand, the low density minimizes formation damage due to an underbalance drilling condition, and eliminates circulation losses. Besides the advantages already mentioned, this fluid has a thermal stability of 280 °F, good transport capacity, resistance to typical...

... well. To quantify the effect of well shut-down on rock stability, a fully coupled geomechanics model accounting for the changes of fluid pressure is developed. The redistributions of fluid pressure in reservoir are analytically solved and coupled with the stress model, while the water hammer equations...

... show that shale stability can be achieved through an osmotic outflow of pore fluid and prevention/minimization of mud pressure penetration. This new generation of membrane efficient water-based drilling fluids generates exceptionally high membrane efficiencies (in excess of 80%). A fundamental...

The first type includes those studying perforation tunnel stability and predicting when sand production may occur. Those...
