The article discusses the possibility of improving design turbine a hydraulic drilling machine for wells in very hard rocks and at considerable depths (5000–12,000 m). analysis results studies on technical technological characteristics downhole motors showed that it is impossible to ensure stable operation due limitation operating temperature, while with an increase flow rate fluid, they do not...

Drilling engineering comprises a major part of production and exploration in oil fields and drilling risk is a significant ingredient to success. As one of the crucial ways to terminate oil spill event, relief well assumes great responsibility. Thus it is essential to analyze and assess the risk of relief well technique before drilling operation in order to guarantee rescue project work smoothl...

I provide a minimal method for generating a mu term and positive slepton masses within the framework of anomaly mediation. I introduce a new operator involving a hidden sector U(1) gauge field which is then canceled against a Giudice-Masiero-like μ term. No new flavor violating operators are allowed. This procedure produces viable electroweak symmetry breaking in the Higgs sector. Only a single...
