Yangquan jinyulong ceramsite sand Co., Ltd. was established on March 31, 2012, with a registered capital of 50 million yuan and a total investment exceeding 100 million yuan. It is a specialized manufacturer of fracturing proppants (ceramsite sand) for oil and gas wells.

Has nobody in the oil industry been talking about production anymore?

Currently, three areas are seeing a sharp surge in technical talent demand: deep and ultra-deep exploration, efficiency enhancement in unconventional oil and gas, and digital intelligence and low-carbon technologies.

Major breakthrough at Shengli Oilfield: China has achieved a historic milestone in the exploration and development of medium- to low-maturity shale oil.

Shale oil is trapped in the pores of tight rocks, where it cannot flow naturally. Typically buried at greater depths and occurring in scattered, discontinuous reservoirs, it is widely recognized as a world-class challenge in global oil and gas exploration and development.

Sinopec has successfully solved a key challenge in oil and gas development in the Hongxing Block!

Shale oil and gas wells are referred to as “artificial reservoirs.” To unlock the reservoir’s production potential, fracturing is required to fracture the shale and create flow pathways for hydrocarbons. The sophistication of fracturing, perforation, and other related technologies directly determines the effectiveness of reservoir stimulation, thereby influencing the per-well EUR.
