Purpose. To rationalize well washing by considering the influence of annular channel limitation, granulometric composition mud, limitation joint movement mud particles, drill string rotation, shape channel, and rheological properties a cleaning agent. Methodology. Applied laboratory studies on drilling fluids are carried out using modern methods analytical analysis experimental studies, in part...

This paper presents a comprehensive study of the microstructure, mechanical and technological properties (formability weldability in solid state) sheet blanks made titanium alloy VT6, developed specifically for superplastic forming diffusion bonding (SPF / DB) PJSC VSMPO-AVISMA Corporation using various technologies. The conducted studies have it possible to establish that sheets VT6 with diffe...

Two field experiments were carried out in order to investigate the effect of chemicalinducers [benzothiadiazole 0.9 mM l-1, oxalic acid 1.0 mM l-1, salicylic acid 0.2 mM l-1] onphysiological and technological traits as well as on yields and antioxidant enzyme activities ofbarley grown under abiotic stress (i.e. water surplus and deficit conditions). Results showed thatrelative water content, le...
