This is a small procedure for dual media testing. Welltest is the main program, the other is subroutine. Fun and fun1 are the pressure calculation function and the pressure derivative calculation function, respectively. During the calculation, you can change the value of different parameters, draw the graph, and study the sensitivity of each parameter to the pressure response. Sensitivity analysis, the parameters can be input 5, 4 and other different values. GUI interface is clear, easy to handle, easy to operate. The preparation of relatively simple, involving a lot of Matlab knowledge, for their own understanding, master the program, the interface is very helpful.
