By changing the position of the M put on the area and
each time hoping the pressure ∆P(t), can be traced to changes in
pressure put on the area.
Then placing wells more convenient to set coordinates
(x 1, y 1), (x 2, y 2), (x 3, y 3), etc., and the position of point M
coordinates (x, y). Then the distance from the point M to be written
using the coordinates of wells
