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 ...

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 ...

Conductor casing Conductor casing is the first string set below the structural casing (i.e., drive pipe or marine conductor run to protect loose near-surface formations and to enable circulation of ...

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.
