Abstract
Many of Brazilian heavy oil reserves are located in the Northeast geographic region of Brazil. Presently, those reserves are being recovered using thermal recovery methods. To investigate the opportunity of improving the performance of configurations based on the SAGD process in fields with the characteristics of the Brazilian Northeast, a numerical simulation study was conducted in a semisynthetic reservoir, reproducing those characteristics. A W-SAGD configuration, with two parallel injector wells, in a different vertical alignment was proposed. Results revealed that keeping a steam injection of 200 ton/day anticipated the W-SAGD-25 oil production, improving recovery efficiency.
