Hello Andy,
Let me indicate some info in addition. Also I trying to find data when refinery plants production starts.

USSR crude oil production in 1938-1945
whole USSR Baku region
1938 - 30,2 mil. ton n/a
1939 - 30,2 mil. ton n/a
1940 - 31,1 mil. ton n/a
1941 - 33,0 mil. ton 23,5 mln. ton (71,2%)
1942 - 22,0 mil. ton 15,7 mln. ton (71,4%)
1943 - 18,0 mil. ton 12,7 mln. ton (70,6%)
1944 - 18,3 mil. ton 11,8 mln. ton (64,5%)
1945 - 19,4 mil. ton 11,5 mln. ton (59,3%)

USSR aviation gasoline production in 1940-1945
1940 - 889 thous. ton
1941 - 1269 thous. ton
1942 - 912 thous. ton
1943 - 1007 thous. ton
1944 - 1334 thous. ton
1945 - 1017 thous. ton

1941-1945 total production was 5538 thous. ton. In addition 82,5 thous. ton captured in East Europe 1944-45 and 2586 thous. ton delivered from USA, Canada, Great Britain.
But 90-92 % of Lend-Leased high grade oil material were used for Soviet aviation gas production. Therefore 1.7.1941 – 1.5.45 USSR production estimated around 4,2 mil. ton of aviation gasoline, but 2,3 mil ton was Lend Leased high octane components included.
Therefore of 4,54 mil. ton all air gas produced. captured etc., Lend Leas share was 57 %.

P.S. Recently l pickup an interesting website, but still not it studied.
Perhabs may be usefull.
