Over the years, the Daqing Oilfield Chongqing branch has independently designed, constructed, and operated the first high-sulfur project pilot development area. The company implemented a management model of grid-based, standardized, professional, and intelligent management to tackle the development challenges of gas reservoirs and ensure a daily output of 1.45 million cubic meters in the pilot area.

The Sichuan-Chongqing exploration area has established an integrated exploration and development model, constructing 27 liquefied natural gas and compressed natural gas test purification stations. A joint project department was established to continuously improve the operational efficiency of stations, maintaining the device operation rate above 94 percent.
