.... 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...

..., elliptical, linear and spherical geometries. This generalized pressure derivative is of the power law type, alld is characterized by a different exponent for each of the flow geometries. Using well test data from analytical solutions for radial, elliptical, linear and spherical composite reservoirs, a graph...

... discussed extensively in the literature. However, the conventional homogeneous decline type curves are not appropriate for composite reservoirs. While production decline curves for radial, composite reservoirs have been presented, the same is not the case for composite reservoirs in elliptical, linear...

... wells undergoing steam injection, a steam chamber containing high mobility steam is established. This steam chamber, which can be of a complex shape, is surrounded by low mobility reservoir fluids. Such reservoir situations are referred to as composite reservoirs. An analytical solution to analyze...

... Abstract A linear composite reservoir is defined as one consisting of two regions of different rock and fluid properties and in which the fluids flow in one direction away from the well bore. Many steam or insitu combustion pilots develop communication paths between wells where fluids flow...
