Abstract

The peculiarities of elastic stresses in open hole wells’ of Gatchina gas storage reservoir are researched. It is revealed that in depression more than 1,5 MPa gas bearing rocks start to destroy. On the basis of studying of correlation relation between technological parameters of gas wells’ production and evacuation of sand the equations of plural regression are constructed. These equations are used to make prediction of sand evacuation at each producing gas well.
