Sinopec, China's state-owned oil and gas major, is intensifying exploration in the ultra-deep shale formations of the Sichuan basin. The move is designed to increase the country's shale gas output by a third over the next ten years, according to a Reuters report.

Shale gas currently accounts for just a tenth of China's total natural gas production, falling short of government expectations. Beijing has set a target of producing 80 to 100 billion cubic meters of shale gas annually by 2030, a goal that has spurred activity among state-owned enterprises.

The Sichuan basin, known for its complex geology and deep shale layers, requires significant technological investment and higher drilling costs compared to conventional plays. Sinopec's ramp-up signals a strategic push to tap these challenging resources.

This effort is part of a broader Chinese energy security strategy aimed at reducing reliance on imported natural gas. The country has been the world's top LNG importer, and domestic production gains could shift global trade dynamics, particularly for exporters in the Middle East and North America.

However, ultra-deep shale development poses environmental concerns, including water usage and seismic risks. Critics argue the high cost and technical hurdles may make renewables a more viable long-term investment for China's energy transition.

Counter argument: Some analysts question whether the ambitious shale gas targets are realistic given technical difficulties, high extraction costs, and past production shortfalls. They caution that China may need to rely on imports for longer than planned.
