In the Don field, North Sea, sealing faults prevent hydrocarbons from migrating into fault compartments on the crest of a large structural high.<ref name=ch10r36 /> Instead, hydrocarbons are trapped in several fault compartments on the flank of the structure against cross-sealing faults that have sand/sand juxtapositions. Wells in three fault compartments (211/18-5, 10, and 16) in the crest of the structure are dry. Hydrocarbons have either been trapped downflank or have been deflected to the southwest by sealing faults.
