Abstract: The effects ofwell trajectory and azimuth on sand production of bare well completion formation have been studied quantitatively in this paper with a commercial finite element software and Equivalent Plastic Strain. The results show that both the maximal plastic strain and the plastic area increase with well angle that ranges from 0 o to 45°at given in-situ stress and formation. The sand production in-creases too. The maximal plastic strain decreases with well angle that ranges from 45°to 90°, and the sand production decreases too.The plastic zone changes with well azimuth, even though well angle is same. It is better for sand control that Well, especially horizontal well drilling should be along with in-situ horizontal stress.

Key words: well deviation, well azimuth, sand reservoir, sand production, finite element
