... terms are zero if the transformation satisfies a system of differential equations that depend on the geometry and rock property distribution within the reservoir. Numerical examples with a black-oil simulator are presented to show the increased accuracy resulting from the use of the curvilinear...

...Curtis O. Bennett; Rodolfo G. Camacho-V.; A. C. Reynolds; Rajagopal Raghavan New analytical solutions for the response at a well intercepting a layered reservoir are derived. The well is assumed to produce at a constant rate or a constant pressure. We examine reservoir systems without in-terlayer...

...C. C. LaGrone; S. A. Baumgartner; R. A. Woodroof, Jr. Reservoirs with bottomhole temperatures (BHT's) in excess of 250°F [121 °C] and permeabilities of less than 1.0 md are commonly encountered in drilling and completing geothermal and deep gas wells. Successful stimulation of these wells often...

...J. G. J. Ypma A two-dimensional (2D) analytical model is presented for gas/oil gravity drainage in a homogeneous, dipping reservoir. The sensitivity of gas/oil gravity drainage to key variables such as injection rate, oil relative permeability, and permeability anisotropy can be determined quickly...

...R. E. Bremer; Hubert Winston; Saul Vela A mathematical model is developed that describes fluid flow and pressure behavior in a reservoir consisting of two permeable zones separated by a zone of low permeability, or a "tight zone." This model can be used to design and to interpret buildup, vertical...

...T. K. Perkins; J. A. Gonzalez When a cool fluid such as water is injected into a hot reservoir, a growing region of cooled rock is established around the injection well. The rock matrix within the cooled region contracts, and a thermoelastic stress field is induced around the well. For typical...
