... challenges for cementing operation. Conventional lightweight system extended by sodium silicate does not meet client well acceptance criteria – no sustained casing pressure (SCP) and successful annular space pressure test due to delayed compressive strength development and relatively high permeability of set...

.... It is assumed that the fault zone are softening after the peak of strength, i.e. the strength decreases with increasing of inelastic deformation until the stress are reached the some residual level. Slipping of fault sides leads to the formation of local subsidence of the surface. It is established...

Such approach, subject to a wide offering of advanced high-strength steel tubes and special alloy tubes resistant to hydrogen sulfide corrosion, helps to solve current...

It is especially dangerous in the first years of operation when the soil is not consolidated enough. Relief in a local zone...
