... gravity drainage processes is very important for the creation and growth of the steam chamber. The steam chamber is the main vehicle for transmitting heat to the cool oil sands at its edges and thus its size, really surface area, is a direct control on the amount of oil produced. In each of the cases...

Simulation results revealed the parameters that will have the greatest impact on the process performance and determined the effectiveness of each hydrocarbon additive in improving...

... of oil production in a SAGD process. Their first goal, however, was to study the feasibility of SAGD and to provide a mathematical proof for expanding SAGD in more sites. After his original theory, Butler tried to modify the theory in steps to overcome some shortcomings such as (a) steam chamber...

... in detail. A simulation study of nine years of performance of Pair 1 was conducted to understand these characteristics. The history match demonstrated that oil production was achieved by two different mechanisms: one was expansion of the steam chamber and the other was drainage of oil from the layer above...

In field practice, the continued existence of the liquid pool is monitored by examining the temperature difference, called the interwell...

With these improvements, rise of steam chamber to the top occurred much earlier, and a favorable tilt-forward-angle of the thermal front was quickly obtained. TTH steamflooding with solvent proved superior to the TTH steamflooding, as the channeling of steam...

The new theory provides predictions of the rise rate which compares better to estimates derived from field thermocouple data and experimental observations than values obtained from Butler's theory. Detailed fine-scale thermal reservoir simulations of the edge of the steam chamber have been done...
