Because of leaky seals—especially lateral seals—many stratigraphic traps have short hydrocarbon column heights. In these kinds of plays, [[reservoir quality]] can be critical. Higher quality reservoirs require less column height to drive water saturations low enough for water-free production. Lower quality reservoirs require more column height for water-free production. | Because of leaky seals—especially lateral seals—many stratigraphic traps have short hydrocarbon column heights.
