Xinjiang has potentially huge untapped reserves, but exploration in the desert province presents complex geological and political challenges
Chinese NOCs are forging ahead with challenging ultra-deep drilling and shale projects in Xinjiang Uyghur Autonomous Region, underlining the far western province's potential importance to the country's drive to meet ambitious energy security plans.
