I have been reading the attached pdf, very fascinating stuff. Compiled immediately postwar.
'Oil as a Factor in the German War Effort, 1933-1945'
http://www.scribd.com/doc/39576251/O...fort-1933-1945
Foreword.
This Report is an account of Germany's oil economy from 1933 up to the
time of her defeat. Its compilation is the result of the work of three groups :
the Technical Sub-Committee on Axis Oil, which has been responsible for
reporting upon Germany's oil position since 1942; the Oil Committee of the
Combined Strategic Targets Committee, which assisted in the direction of the
Allied air offensive against oil targets; and the Inter-Departmental Bombing
Survey.
The compilers of the report have had access to all the relevant records so far
available, have interrogated German officials and have examined many of the
bombed targets. The facts thus obtained have provided a record of the efforts
made by the Germans to safeguard their oil supplies, of the success of the Allies
in destroying the sources of production, and of the extent to which shortage of
oil is reported to have influenced military operations.
The Report attempts to summarise the evidence now available on these
questions so that those in possession of similar evidence on all the other factors
involved may put in its correct perspective the part oil played in the military
defeat of Germany.
