Paper Number: PETSOC-2009-102
... 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...

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...

... 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...
