Groundwater, forming a system with an oil reservoir, comes to the surface (Fig.). What should be the density of the clay solution used during drilling (Pmin) so that oil does not gush out when the formation is opened? Well depth h = 2500 m; the distance between the level of groundwater release to the surface and the water-oil boundary h1 = 3200 m; the distance between the level of groundwater release to the surface and the wellhead h2 = 600 m; groundwater density Pw = 1100 kg/m3; oil density Pn = 850 kg/m3.
