Negative factors affecting the integrity of production strings and methods for preventing leakage
The main element of the well design, which determines the life of the wells, is the production strings (PS). Premature failure of the production strings requires significant expenses for its restoration, and the unprofitability of its restoration by repair methods leads to unjustified expenses for abandoning the well and drilling a duplicate well. The article briefly describes the impact of negative factors on the integrity of the PSs of the wells and outlines the possibilities to reduce their impact. Specific recommendations are offered.
