[[Accumulation]]s should be dated to evaluate the potential importance of accumulation destruction in an area of interest. Leakage, spillage, petroleum destruction, and cementation are more likely to alter the size and quality of old accumulations than young accumulations. Young accumulations with active petroleum charge are more likely to be affected by displacement of oil by later gas charge. Accumulation preservation is a function of tectonic setting, trap type, depth of burial, and seal type.<ref name=ch11r24>Mcgregor, D., S., 1996, Factors controlling the destruction or preservation of giant light oilfields: Petroleum Geoscience, vol. 2, p. 197–217., 10., 1144/petgeo., 2., 3., 197</ref>
