In the first quarter, DaQing Drilling saved a cumulative total of 6,545 tons of diesel fuel, leading to a direct cost reduction of 48.52 million yuan and marking a phase of success in its green production initiatives. Throughout the quarter, the company continued to advance energy substitution in its drilling and fracturing operations, actively promoting electric-powered drilling and fracturing in its main exploration areas. Exemplified by the DaQing Gulong National Shale Oil Demonstration Zone, drilling crews accelerated the grid-connection of drilling rigs. The use of electric power effectively reduced on-site noise and improved the continuity of drilling operations. Drilling operations consumed 128 million kilowatt-hours of electricity in the first quarter, with the electrification rate rising to 64.3%, an increase of nearly 5 percentage points compared to the same period last year. Breakthroughs were also made in electric fracturing technology, with completed pump injection volumes exceeding 150,000 cubic meters. DaQing Drilling also enhanced the refined management of electricity usage in offices and workshops, achieving an electricity saving of 1.77 million kilowatt-hours year-on-year.
For remote well sites not covered by the power grid, DaQing Drilling flexibly implemented gas-for-diesel and methanol-for-diesel substitution. In exploration areas such as DaQing, Jilin, and Shaanxi-Shanxi, the company deployed 31 sets of gas-fired power generation equipment and 2 sets of methanol power generation equipment, completing a total of 99 wells. The No. 1 Drilling Branch specifically formulated operational plans for gas and methanol substitution, with 16 drilling crews having fully transitioned to clean power alternatives. Among these initiatives, electricity generated from 'gas-for-diesel' accounted for nearly one-third of the total electricity consumption for drilling, saving 1,609 tons of diesel and reducing costs by 13.2 million yuan. A pilot project for 'methanol-for-diesel' at a single well saved over 180,000 yuan in costs, freeing field operations from reliance on traditional diesel engines and simultaneously reducing both fuel costs and equipment maintenance burdens.
In markets outside its primary region, the company adhered to the principle of "using electricity where possible, gas where suitable, and flexible supplementation." Significant results were achieved in the Sichuan-Chongqing area: 15 out of 16 construction teams were connected to the power grid, with electrification accounting for 72% of the footage drilled, an increase of 21 percentage points year-on-year. For well sites that could not be immediately connected to the grid, on-site technical teams developed transition plans tailored to terrain, schedule, and power requirements for each site, striving to maximize the rate of pre-drilling electrification and the proportion of electricity used in operations. Exploration areas like Shaanxi-Shanxi and Xinjiang promoted substitution projects based on local conditions, extending clean power coverage to more drilling footage. The integrated clean energy system for drilling—"electricity/gas/methanol-for-diesel"—established by DaQing Drilling was also selected for the China Enterprise Confederation's "2025 Outstanding Practices for Enterprise Green and Low-Carbon Development" case studies.
