Arbuzovskoye Oil Field
The Arbuzovkoye field (formerly Varyakhskaya prospect) is located in the north central part of License 61 about 10 km east of the Lineynoye oil field. This structure was delineated and prepared for drilling by seismic data in 1990-91. Additional seismic data was obtained by PetroNeft in 2005/2006. The Arbuzovskoye No. 1 discovery well was drilled in 2010. The well tested open hole with an inflow of 289 bopd from Upper Jurassic J1 sandstones (2,557.3 to 2,586.0 m MD). A step rate DST was performed and stabilised flow on an 8 mm choke was 176 bopd (2,564.9 to 2,570.9 m MD). The oil is high quality with a density of 0.79 g/cm3 (47 degree API gravity).
According to the log interpretation the Upper Jurassic J1-1 sandstone was penetrated from 2,565.8 to 2,573.2 m TVD (true vertical depth subsea). The reservoir is completely saturated with oil throughout and the effective net oil pay is 5.1 metres.
Ryder Scott currently estimates the proved and probable reserves for the field at 13.2 million bbls. The 3P reserves for the field are estimated at 17.4 million bbls.
The RF State Reserves Committee (RKZ) has approved C1+C2 reserves for the field at 10 million barrels and the Pilot Production Project for field development was approved by the RF Central Development Commission in November 2011.
A 10 km pipeline and utility line were constructed from the Lineynoye central processing facility to the Arbuzovskoye field in Q1 2012. Plans are to drill from 8 to 10 development wells at Arbuzovskoye in 2012.
