.../ further development of these insights would be useful in optimizing performance of water floods/ improved oil recovery projects. Introduction Significant variations in performance of various water floods observed in the field are often attributed to differences in geological/ reservoir features...

... to an imposed pressure gradient. Small scale variations in the clastic deposits of the McMurray cause permeability to be variable and direction dependent. Permeability in the vertical direction is of primary concern because operators are concerned with (1) the rise of steam through the formation, (2...

... variation of thermal stress as well as non-uniform loading over the perforation intervals due to sanding-out are major causes for casing failure. Casing with thicker wall and higher steel grade is used in well completion along with thermal stress compensator, prestressed casing and end locker...

... has good intergranular porosity and high permeability while the upper channel has a mixed composition that can lead to porosity and permeability variations and flow barriers. The area has been under primary production since the early 1980's with the use of horizontal producers by the mid- 1990's...

Two base cases and the underlying process mechanisms were established, one assuming primary production process and one assuming steam-assisted gravity drainage process. We then performed sensitivity studies of the different fluid property variations...

... by deltaic fans [1] . Considerable variation in sand thickness occurring over short lateral distances is characteristic of this particular deposit and thick layers with high permeability are patchy and isolated. The sediment underlying the project area is finely grained and relatively clean quartz sand...

... Abstract Warm VAPEX, as one of the variations of vapor extraction process, is investigated in the current research which incorporates heat in a VAPEX process. The idea behind it is to heat the solvent above the dew point temperature of solvent vapors at reservoir conditions and inject...

... Abstract Temperature measurements are widely used for SAGD real time monitoring. Nevertheless field DTS data demonstrates presence of the strong temperature variations across the SAGD producers and therefore introduce uncertainty in interpretation of the temperature data. This work is devoted...

Although reservoir temperature is a key control on biodegradation, large variations in oil properties have been documented in accumulations from similar depths within a play area. Data from the Liaohe Basin, NE China and other basins in China and elsewhere, indicate...

... Abstract The defining characteristic of heavy and super heavy oilfields is the large spatial variation in fluid properties, such as oil viscosity, commonly seen within the reservoirs. Traditional heavy oil and tar sand exploration and production strategies rely significantly...
