Screen sizing rules and running guidelines to maximise horizontal well productivity

摘要

Flow density across sand control screens in horizontal wells is very low. This is very favorable to the selection of screenonly completions as a cost effective sand control measure. However, phenomena specific to horizontal well completions have prevented them being as successful as they could be: 1) deployment contaminates the screen and reduces well productivity; 2) formation sands can mix in the annulus around the screen, modify the apparent sand sieve analyses, and affect the screen's ability to retain sand.
