FALLOUT: Russian Industry Faces Code Crisis as IT Providers Pull Out.

“All industries are facing the same problems,” Dunaev said. “Many processes in modern units are controlled by software.”

The exodus is a challenge for the nation’s oil and gas industry, where domestic software accounts for only 5% to 10% of industry-specific tools and is often “suboptimal,” according to First Deputy Energy Minister Pavel Sorokin.

The situation is made worse with the depletion of Russia’s traditional oil deposits, forcing producers to tap hard-to-recover reserves that require more complicated equipment and programs if the country wants to maintain output at current levels.

Just what the world needs right now: Less oil.
