... flow we only need the shape factor in addition to the area. If we use the direct approach, and assume that the asymptote is equal to the average pressure, then we need the same type of information to make a proper choice of interval where the hyperbola should match the buildup curve. For the direct...

... parameters from pressure buildup curves for an infinite two- layered oil reservoir. Equations were derived that define the pressure behavior at the wellbore. Pressure drop equations were derived for the upper and lower zones using Hartsock's method.2 From these pressure drop equations, other equations were...

The Horner pressure buildup method is gener- ally accepted as the best means of deter- mining reservoir data from short time tests such as a drill stem test. The Horner method requires that the steady state or straight line portion of the buildup curve be reached...
