... year of operation, pressure and oil production rates decreased when steam injection rates were reduced. After the second year of operation, oil production rates responded inversely to steam injection rates. Oil rates were reduced when steam rates were increased and oil rates increased when steam rates...

... natural depletion for 17 years (2) steam injection temperature of 582°F and 80% quality (3) producer minimum flowing BHP of 145 psia (4) For Category 1 and 2 runs, the steam injection rate is constant at 150 BPDCWE into the model (i.e. 1200 BPDCWE per injector in a 5-spot pattern). For Category 3 and 4...

.... Secondly, SAGD performance was optimized by adjusting steam injection rate and producer liquid withdrawal rate during different SAGD operation periods. Finally, experimental design and response surface generation techniques were applied to build a polynomial response surface through which the net present...

... in separate simulations. Propane, pentane and naphtha were co-injected at a constant ratio relative to the steam injection rate, expressed as a mole percent. Propane and pentane properties can be found in the literature(5)(6). Naphtha was represented by three pseudo- components, nap46, nap116, and nap173...

...(18). The operating conditions, which can be controlled, include the spacing between injector and producer, steam injection rate, and SAGD well pattern spacing. It is very important to find out the proper operating conditions for SAGD optimization under the various reservoir conditions. Simulation...
