Abstract

Efficiency and reduction of operating costs are conditions that oil and gas companies demand from services they purchase. Oil industry faces a new crisis and these events tend to increase the demands to achieve optimization. The industry requires Hydraulic Jet Pumps (HJP) with more efficient designs, even at an energy level that work in the range of their hydraulic capacity. However, factors such as fluid properties, reservoir parameters and surface installation can generate failures which must be characterized to understand their occurrence and behavior. Improve designs, operations and maintenance programs can increasing the reliability and lifespan of the pumps. Downtime in the HJP are dominated by chance and occurred in asymmetric times, for this reason a classic study of probability by normal or exponential distribution is limited. Weibull distribution is the best option for modeling downtime thanks to its versatility, which adapts to any type of experimental data. Additionally, it also helps to obtain results with greater adherence to the operational reality in an oil field.
