An Improved Pressure Derivative Algorithm of the Well Test Data───一种改进的测试数据压力导数计算方法
During transition period, the curves of pressure derivative is below 0.5 infinite acting radial flow straight line, assumes a concave shape.
The larger the storability is, the smaller the peak value of pressure derivative is.
This technique utilizes characteristic points and slope of characteristic straight line on log-log plot of pressure derivative vs time to calculate parameters quickly and accurately.
