Third Meeting of the Heavy Oil Group
General Info – History of Siri
Reservoir
1975 – Discovery of Badejo Field (1-RJS-13).Siri reservoir was not tested as there was no interest in heavy oil.
1981 – Start of the production of Badejo Field.
1997 – Formation test in 7-BD-11A.Production rate of 95 m3/d. Viscosity at reservoir of 320 – 380 cP.
2002 – Reservoir acquisition data well (ADW) proposed (horizontal well of 2000m).
2004 – Drilling of horizontal well, 9-BD-18HP.Oil rate during test: 350 m3/d with ESP. Bottom hole fluid monophasic sample. Pilot production system proposed.
Apr/2008 – Start of pilot production system.FPSO Cidade Rio das Ostras
2015 – Beginning of definitive production system.

Third Meeting of the Heavy Oil Group
• Reservoir-
Water injection: low swap efficiency due the mobility ratio favorable to water;
-
Reservoir pressure near the bubble point (ΔP~12 kgf/cm2);
-
Improve the efficiency of well acidizing to maximize the effective horizontal length (up to 2000m).
• Other areas- Flow assurance in wells with oil viscosity of 314 cP
(reservoir condition);
- Drilling/completion wells in shallow reservoir (~1000m) and with ESP;
- Avoid the occurrence of gas lock in ESP;
- Temperature in proccess
system over than 130oC;
- Difficulties in gas/oil separation (need of chemical products injection).
