Forecasting the technical efficiency of mobile workover rigs

Purpose. To propose a method of comparative evaluation technical efficiency mobile workover rig by the criterion life cycle cost. Methodology. The proposed is based on determination specific discounted costs related to condition machine, spent conventional unit work performed. It combines economic and indicators that characterize performance machine. This makes it possible indirectly assess its efficiency. Procedures for obtaining processing input information, analytical dependences establishing components mathematical model solution are shown. Findings. Using method, comparison performed three similar models rigs, which positioned as more reliable, two less reliable cheaper. Their formed weighted average analysis an array statistical information. obtained values were used determine maintenance rigs in working order period time; characterized indicator these such characteristic points moment balancing expenses, expenses forecasted operation, periods operation at balanced. confirmed usually gain from greater durability far exceeds reduction effect rise price Originality. engineering forecasting technological machines using available engineers petroleum industry. Practical value. assessment intended objectively compare several analogue make reasonable choice efficient
