Illegal waste dumps on state oil giant Rosneft s fields in the Khanty-Mansi region alone could do more than $8 billion in environmental damage, according to one of three reports commissioned by the Russian Health Ministry and obtained by Radio Svoboda, which is releasing them to the public in their entirety for the first time.
Drillers use specialized fluids that include oil, water, and other chemical
additives, depending on the soil type. The average well depth is 3,100 meters, though many are 5 kilometers or deeper.
On average, drilling produces around 560 tons of waste per 1,000 meters, according to oil-industry sources. According to data from Russia s Energy Ministry, 28.5 million meters were drilled in Russia in 2019, the most recent year for which data is available.
