Kondrashevskoye Oil Field The Kondrashevskoye field (formerly Korchegskaya prospect) is located in the north central part of License 61 between the Lineynoye and Tungolskoye oil fields.  This structure was delineated and prepared for drilling by seismic data in 1990-91. Additional seismic data was obtained by PetroNeft in  2005/2006 and 2006/2007.   The Korchegskaya No. 1 discovery well was drilled in 2008.  The well tested an inflow of 125 bopd from Upper Jurassic J1 sandstones (2,469.35 to 2,473.35 m TVD SS).  Core and petrophysical analysis indicates 3.25 m of net pay in this interval.  The entire J1 sandstone was oil saturated in the well and further drilling will be required to define the oil water contact for the field.  The oil is high quality with a density of 0.790 g/cm³.  Ryder Scott currently estimate Kondrashevskoye  SPE 2P reserves at 8.11 million barrels of oil.  The ultimate figure could be much larger provided the structure is filled to the spill point which is common for the Upper Jurassic  J1 reservoirs in the area.  The Russian registered C1 + C2 reserves were approved in December 2008 at 19.08 million barrels of oil.
