SEAL- A lithologic unit which significantly impedes the flow of hydrocarbons.- Therefore, a permeability barrier must exist for the updip migration of hydrocarbons to be prevented.Pore throat size is the major control on the ability of hydrocarbons to enter the pore network of a given rock. It is a rock that has pore throats too small and poorly connected to allow the passage of hydrocarbons. Brittle lithologies tend to develop fractures while ductile lithologies tend to flow plastically under deformation.PROPERTIES OF EFFECTIVE SEALS- They have small throat space (i.e. finegrained)- Laterally continuous- Maintain uniformity of lithology over largeareas- Relatively ductile MAJOR TYPES OF SEALS- Shales 65 %- Evaporites 33 %- Carbonate 2 %GEOLOGIC TRAPSIn addition to the requirement that source rock exists for the generation of hydrocarbons, and that reservoir rock exists for the storage and production of the generated hydrocarbons, traps must also exist to trap, or seal, the hydrocarbon in place forming a hydrocarbon reservoir.What are the types of traps?A. StructuralB. StratigraphicC. Combination A.Structural TrapsStructural traps are created by the deformation of rock strata within the earth's crust. This deformation can be caused by horizontal compression or tension, vertical movement and differential compaction, which results in the folding, tilting and faulting within sedimentary rock form
