 Thus, the much larger Shtokman and Yamal developments will have to provide the bulk of new production capacity, by adding 70 and 200 BCM per year, respectively.Investments in the development of Shtokman and Yamal are forecast to account for over 40% of Gazprom's total expected capital expenditure over the next 20 years.Although Shtokman has been shelved at least for the time being due to relatively low gas prices and high costs, the project may still be resuscitated during the coming decades, depending on developments in unconventional gas and the supply–demand picture.
