"...Drilling deep into the crystalline granite of Sweden between 1986 and 1993 revealed substantial amounts of natural gas and oil. 80 barrels of oil were pumped up from a depth between 5.2 km and 6.7 km.
Russian petroleum geologists followed this operation closely. Dr. P.N. Kropotkin reported at a meeting in Moscow that the discovery of oil deep in the Baltic Shield may be considered a decisive factor in the hundred year old debate about the biogenic or abiogenic origin of oil. This discovery was made in deep wells that were drilled in the central part of the crystalline Baltic Shield, on the initiative of T. Gold.
Drilling into crystalline bedrock is now underway in Russia on a large scale. More than 300 wells have been drilled to a depth of more than 5 km and are productive, as also is the giant White Tiger field offshore Vietnam, mostly producing also from basement rock."
However there may be better ways of educating oneself than relying on Gold's website for info. A Google search brings up this article:
The particular subject of this article is the application to such evaluation of the modern Russian-Ukrainian theory of abyssal, abiotic petroleum origins, an extensive body of knowledge which has been developed and applied during the last forty years. 1996
One of the citations is:

Apparently, Gold got his theory from the Russians, not the other way around.
