... Abstract Low-permeability, low-production, low-abundance are the major features of the low-permeable gas reservoir. Commingling production has been widely used as an important method to improve the producing ability of gas reservoirs, however, the dynamic analysis and technical countermeasures...

... Abstract In tight gas reservoirs, horizontal wells have been used to increase reservoir contact and hydraulic fracturing has been applied to further extend the contact of the reservoir. Point source solution has been used to describe the flow behavior. The method was advanced to the volumetric...

... permeability and altered zone permeability and radius for multiple commingled layers. However, the previous model mainly applies for single-phase oil flow. A new wellbore/reservoir coupled flow model has been developed for multilayer commingled gas reservoirs including both damage and non-Darcy skin in each...

... Abstract Western Sichuan deep tight gas reservoir is characteristic of ultra low permeability, natural fractures developed in heterogeneity, partial ultra low water saturation, hard and brittle shale interlayer. The matrix permeability varies between 0.001mD and 0.1 mD, and the natural fracture...

... Abstract The developments of gas fields and laboratory experiments present that there are great differences in the well performance and well productivity between different wells with the same reservoir petrophysics. The characters and distributions of the tight gas reservoirs are not yet well...

... Abstract Natural gas of volcanic gas reservoirs in China is rich in resources, and its exploration and development is great potential, but the study of the volcanic gas reservoir is a brand new field, there are a lot of difficulties in this study field. Due to the key problem of describing...

... will not stop absorbing water until the irreducible water is saturated. Then the increasing water forms a thick water film, which narrows the flow channel of reservoirs and even leads to water blocking. For the low permeability gas reservoirs, water blocking is more serious. It can make the permeability...
