| Abstract: | In circular reservoirs, an analytical solution is presented for a horizontal well at constant bottomhole pressure by means of both integrated sources and integral transforms. Then rate decline formulas are deduced according to the Duhamel theorem as well as figured using the Laplace numerical inversion. Concrete methods of the decline applications, illustrated by an example in the paper, can be employed to obtain the horizontal well production forecast. |
