... in the multi-transformed spaces are inverted, providing solutions that are analytical in 2 or 3-space dimensions and account for the non-linearity of gas flow. The PTDM solution was coded in a FORTRAN95 program that used (a) the Laplace Transform Analytical solution for the q -problem and (b) a Finite...

..., work to resolve these limitations is well advanced. The TDM Decomposition Stage Step D1: The Laplace Transform of the General Equation of Flow Taking the Laplace transform of Eq. 1 yields (12) ∑ d ≡ x , y , z λ d ( ∂ 2 Ψ ∂ d 2 ) = C T s...

... The idea is to take the Laplace transform of the system impulse response g(t), transfer function, as the reference for the cases where it is available. The physical meaning of a step response to a reservoir model is to have zero flow before the initial instant (t = 0) and then start flowing...
