Petroleum Geology question that deals with types of traps?

Oil has migrated through a gently-dipping, poorly cemented sandstone layer. Up-dip, the sandstone grades laterally into a well-cemented zone. What type of trap is this?
I know it is a stratigraphic trap, but we are supposed to give the specific type of stratigraphic trap. Thanks for the help though

    A Porosity pinchout trap…a type of Stratigraphic Trap..it can also be a diagenetic trap. Tell your darn teacher to stop teaching crap that he/she knows so little about. These are very bizzare and subjective questions.
