gravel pack control

Gravel Pack an overview | ScienceDirect Topics

Both open hole and casing gravel pack completions have the same mechanism of sand control Under open hole gravel pack completion, the gravel bed at the bottom of the borehole acts as a sand filter—it only allows fluid to pass through, not formation sand Under the casing gravel pack completion condition, the wirewrapped screen matching the grain size of sand produced and03/05/2016· The most widely used sizing criterion1 provides sand control when the median grain size of the gravelpack sand, D50 , is no more than six times larger than the median grain size of the formation sand, d50 The upper case D refers to the gravel, while the lower case refers to the formation sand The basis for this relationship was a series of core flow experiments in whichGravel pack design PetroWiki
