Tight sandstone gas reservoir normally has a poor pore connectivity and a low productivity
of single layer production, and the multilayer co-production technique has received …

Matrix permeability is the primary transport property for shale gas recovery, due to the
special production process of gas from matrix to wellbore. With the micro pore size of shale …

The coupling effects of complex pore structure and poor reservoir properties generally lead
to relatively low production of single layer in tight gas reservoir. The multilayer or multilayer …

Hydraulic fracturing is generally considered a promising stimulation technology for low-
permeability gas hydrate reservoirs. Nevertheless, the fracturing behavior of multilayered …

During the water injection development process of highly deviated wells in low-permeability
reservoirs, the water flooding distance between different layers of the same oil and water …

Perforation operation is critical in bridging completion and production enhancement
operations. At the same time, the perforation parameters also affect the structural integrity of …

A series of complex horizontal wells have been implemented in challenging gas reservoirs.
Multilateral horizontal well technology can be used in multilayer gas reservoirs, facilitating …

Deviated wells are used to improve the performance of carbonate reservoirs with multiple
heterogeneous layers and penetrate the “sweet spot” of each layer, which is full of fractures …

To estimate production behaviors of inclined well in multilayer heterogeneous carbonate
gas reservoir, two semi-analytical models for different formation distribution patterns are …

For a carbonate gas reservoir, there are mainly three porous types: pores, natural fractures,
and vugs. According to the different combinations of diverse pore types, in fact, the …
