Key words: short-term cycle of operation, marginal well exploitation, energy efficiency.

There are considered matters of efficient marginal well operations. There are basics of mode selection of periodical short-term ESP operations considering the achievement of bottomhole pressure (BHP) and reduction of risks of premature failure of equipment. Achieved results considerably simplify the process of equipment selection, its mode of operation and work adjustments.
