Sand control in horizontal and deviated wells - PetroWiki

Horizontal well completions have been used in a variety of situations to increase well productivity, improve reservoir management, and access incremental reserves that could not be developed economically with vertical wells. While the first horizontal wells were drilled in competent formations, eventually soft formations were completed horizontally, leading to sand …

HORIZONTAL GRAVEL PACKING - Petroblogger.com

The basic method for gravel packing process in horizontal wells is governed by two stages. In the first, the slurry (fluid transport and gravel) is pumped through the pipe to reach a larger section flow area below the packer, which slows the flow and the gravel begins to be deposited in the bottom of the hole forming dunes that increase in ...
