a change in the formation that may have been caused by ancient erosional forces. Accounts for variances in formation tops in near-by offset wells in a formation with no pay inclination.

n: a complex assembly of cylinder or taper that separate the solid from liquid according to the theory of centrifugal sedimentation.

n: natural porosity in petroleum reservoir sand or rocks, i.e., the porosity developed during the original sedimentation process. Formations having this property (such as sand) are usually granular.

n: the possible sequences of events, all interrelated, by which rocks may be formed, changed, destroyed. or transformed into other types of rock. The events include formation from magma, erosion, sedimentation, and metamorphism.
