Prior to 2008, shale gas reservoirs were deemed uneconomical to produce. Hydraulic fracturing and horizontal drilling have shifted this perspective, reducing the flow resistance from the reservoir to the well. Notwithstanding the thousands of shale…
Due to advances in hydraulic fracturing and horizontal drilling, the abundance of inexpensive natural gas has revolutionized the energy industry. As the world population increases, natural gas will play a prominent role in satisfying new energy…
Shales are generally treated as non-porous formations and are frequently considered as the source rock and the cap layer. Over the past decades, technical breakthroughs in the US such as horizontal drilling, multi-stage hydraulic fracturing,…
For rational design of drilling process parameters and guarantee of safe drilling, law of carrying cuttings in horizontal well drilling of marine natural gas hydrate should be intense research to effectively reduce the friction of drilling tools and…
The Cornegliano Laudense Natural Gas Storage Project consists in the conversion of a depleted gas field into two underground gas clusters interconnected by a DN600 (24") clad gas pipeline at 170 barg. A major design challenge of the interconnection…
The Sinian Dengying Formation gas reservoir in the Anyue Gas Field of the Sichuan Basin is an ultra-deep ancient dolomite karst gas reservoir, whose development is of high difficulty, for the reservoir is thin and scattered with strong heterogeneity…
Natural gas hydrate (NGH) is one of the potential green alternative energy sources, and its exploration and development has become one of the key directions of energy development in China. In order to solve the problem of wellbore instability in the…
Horizontal wells can significantly improve the gas production and are expected to be an efficient exploitation method for the industrialization of natural gas hydrates (NGHs) in the future. However, the near-wellbore hydrate is highly prone to…
Shales are generally treated as non-porous formations and are frequently considered as the source rock and the cap layer. Over the past decades, technical breakthroughs in the US such as horizontal drilling, multi-stage hydraulic fracturing,…
