oa Predicting Productivity of the Horizontal Well Inside Limited Reservoirs

In the present paper new flow rate formulas for horrzontal and slanting well in isotropic and anisotropic reservoirs are presented. These formulas accurately approxímate dependenties of the well productivíty on geometric and hydrodynamic parameters of the system «reservoir + well» such as length, radius, and slanting angle of the well, distance to the external reservoir boundary, thickness of the lager, permeability, and anisotropy degree of the reservoir.
