Good engineering design and execution of gravel pack procedures can and have increased the oil flow rates of wells in the Gulf of Mexico by many thousands of barrels per day. However, many completions have failed to perform at design rates. The primary reason is that design methods have neglected the effect of the damaged formation around perforations. If damaged perforations are considered along with the effects of perforation washing, well flow analysis can better predict expected well productivity and help select better completion procedures.
