Abstract: This paper utilizes Fair's model,taking both wellbore storage and skin effect and "humpeffect" to interprete the well testing records of a single well in a homogeneous reservoir.Laplace's transform is applied firsst, then residual theory is used,and finally integral inversetransform is performed to give a solution in the real space, This method differs from previousrnethod which gives a form of Laplace,s numerical inverse transform. Therefore, it has highaccuracy and requires a shorter time,because a concrete form of the solution are given.Thus,it improves the structural system of those solutions for well test of a single well in ahomogeneous reservoir,Finally,some actual field examples are given to illustrate the methodpresented.
