Influence of solvent injection temperature in steam-solvent assisted gravity drainage process for heavy oil reservoirs of Brazilian Northeast

چکیده
The solvent–steam assisted gravity drainage is an oil recovery process that combines the advantages of thermal and miscible effects, it has been successfully tested, especially in Canada, where many heavy reservoirs are located. This method uses two parallel horizontal wells drilled one above other, upper injects steam solvent lower produces oil. not applied yet Brazil, there reservoirs, northeast region. Based on this context, research aimed to study application ES-SAGD a semisynthetic reservoir, with characteristics similar those found Brazilian Northeast, specifically analyze influence injection scheme ES-SAGD. Numerical simulations were performed using commercial software from CMG. It was analyzed several steam-solvent rates, injected temperatures for solvent, (at reservoir or at temperature´s), order minimize explosion risks, can be due high temperatures. Results showed temperature great recovery, better production when inject hot because cold generates cooling steam. However, possible temperature), increase production, changing some properties, avoiding explosions risks.

The Biqian-10 block, located in Henan Oilfield of Sinopic, contains many thin and interbedded reservoirs, which have been operated by cyclic steam stimulation for 20 years or more. Therefore, it is a challenge to implement the conventional steam flooding. In order to improve the recovery of steam flooding, urea was used to assist steam flooding. Urea can decompose into CO2 and NH3, which are be...
