A Study of Steam Assisted Gravity Drainage
Performance in The Presence of Non-Condensable Gases
The objective
of this research is to discuss the applicability of carbon dioxide and steam
injection methods to Batý Kozluca
and similar heavy oil fields. In order to reach this goal experiments and
thermal numerical simulaton techniques were used. Different horizontal and vertical well
combinations, steam and carbon dioxide injection rates
were used in order to create a database that can be used to evaluate pilot and
field applications in such fields. The experimental results showed that
steam assisted gravity drainage systems show better performance compared to
vertical and horizontal injection systems with steam and steam/carbon
dioxide. Steam/n-butane injection is not superior to steam/carbon dioxide
injection. Similar results were obtained in
experiments where limestone core plugs were used. The experiments were simulated using a thermal numerical simulator.
