Numerical algorithms based on the theory of ill-posed 
problems are suggested for estimation of the filtration parameters 
of a bed using the results of hydrodynamic studies of vertical wells. 
These algorithms allow determination of the coefficients of compressibility, 
efficiency, and hydraulic conductivity of the critical and distant 
zones and interpretation of the results of the hydrodynamic studies 
with account for the dependence of the filtration parameters on pressure
