In recent years, environmentally-assisted cracking has caused failures of many Grade P110 couplings during fracturing operations, causing enormous economic loss to the oil and gas industry. Factors ...

Operators can avoid failure of couplings during hydraulic fracturing by using a design window when designing a casing string. Hydraulic fracturing treatments produce higher stress levels in couplings.

Once a well has been drilled, if it is to become a production well, the well must undergo completion. While drilling a well cuts through the rock formations and allows drilling engineers to reach the ...
