Sažetak
Certain risks are very common to any application of a downhole control system during workover, while others will be field-specific or at least increased or decreased by the given well conditions. Workover anomalies may be caused by erosion, corrosion, mechanical errors, temperature effects on electronics, wear and tear on the dynamic seals or seizure of moving components. Obviously, the simpler the system and the fewer moving parts, the fewer components are available to fail. Procedures and supporting control software must be developed to ensure optimum system use. Blowouts are not very common today as most of blowout preventing systems serve the purpose. But, occasionally, these systems may fail due to either technical problems on the wellbore equipment or human error. Both reasons can cause an enormous damage on wellbore equipment, reservoir, surface facilities or even human loss. The right accidental risk assessment approach can reduce chances of repeating bad scenarios happened in the past.
