Quantitative correction of influence of rain on well water level

In this paper a new method of the quantitative correction of influence of the rain on the water level in a well is given. Using the faltung filtering and polynary regression, considering the effect of the rain on the well water level with the lag “memory”, the correction of the influence of the rain on the well water level is made. The result of correction of the water level in the well Lu-08 by the rain shows that the correction result of this method is better.

Thank The Seismic Office of Victory Oil Field for their help in gathering data of the well Lu-08.
