ABSTRACT:
A tortuous path sand control screen (40) for reducing the velocity of particles (66) traveling therethrough is disclosed. The tortuous path sand control screen (40) comprises a base pipe (42) and a screen wire (48) wrapped therearound having turns (50, 52, 54) which extend along at least a portion of the length of the base pipe (42) forming gaps between adjacent turns (50, 52). The screen wire has a profile (62, 64) that reduces the velocity of the particles (66) traveling through the gaps, thereby minimizing erosion of the tortuous path sand control screen (40).
