... horizontal well with multiple fractures, combined the reservoir model and type of reservoir derive with the hydraulic fracture model is first established in this paper. The numerical models and the corresponding solution are first derived. Both fracture performance and reservoir performance in the transient...

.... Instead, there is an intermediate region between the inner and outer regions, which is characterized by a rapid, yet smooth, decline in mobility and storativity. As an improvement over the two-region model, three-region and multi-region composite reservoir models have been proposed. However, these models...

.... The paper concludes that real shallow reservoirs are often more accurately modeled using the composite and multi-composite reservoir model. It further concludes that careful engineering judgment is required when using the material balance approach in gas reservoirs to determine the original gas in place...

... and, both theoretically and experimentally, for the reservoir model Two different methods have been tested for limiting overall gas production. The first method uses a gas-liquid downhole separator whose main component is a membrane permeable to water and oil but impermeable to gas. Nevertheless...

... in southeastern New Mexico. Conventional models fail to match these field data. Instead, a model for a heterogeneous reservoir with a fractal structure provides a quantitative analysis. The fractal reservoir model reduces to the conventional solution in the case of a homogeneous reservoir. Introduction...

... problems, each of which must be solved separately. The three dimensional single phase reservoir model is also fully implicit, as is the well model. A significant feature of the well model is the cross-flow capability in multilayer completions. The large amount of data used in the model is supported...

... is therefore assumed to be less than thecurrent well spacing. A reservoir model containing the low permeability zones was constructed bystatistical analysis. Their lateral extend was assumed to be equal to half thewell spacing, and their position in the vertical sequence derived from theresults of log...
