Advanced drilling technology makes it possible to penetrate oil and gas sites with deep bedding of reservoir, a complex multi-layer structure high reservoir temperature at the well bottom, reaching 150°C. The difficult geology strata leads fact that productive layers are flooded unevenly. In this work causes for water cut in reservoirs given, repair insulation technologies isolation water-beari...

Base isolation techniques have emerged as the most effective seismic damage mitigation strategies. Several types of aseismic devices for base been invented, studied, and used. Out several systems, sliding systems are popular due to their operational simplicity ease manufacturing. This article discusses historical development passive such pure friction pendulum isolators with other surface geome...
