Analytical methods are presented to determine the pressure- transient behavior of multibranched wells in layered reservoirs. The computational methods are based on Laplace transforms and Numerical inversion to generate type curves for use in direct Analyses of pressure-transient data. Any number of branches with Arbitrary direction and deviation can in principle be handled, al- Though the computational cost will increase considerable with in- Creasing number of branches. However, due to practical consider- Ations, a large number of branches is also unlikely in most cases.
