− | The critical moment will be different for the middle Miocene, lower Paleocene, and lower [[Tertiary]] source rock. The critical interval encompasses the composite of all critical moments. The critical interval for the East Breaks 160-161 petroleum system is 2.8 Ma to the present. It is that time period after deposition of the reservoir and seal during which subsequent growth fault movement formed the anticlinal trap and accumulation of migrating hydrocarbons occurred. | + | The critical moment will be different for the [[middle Miocene]], [[lower Paleocene]], and lower [[Tertiary]] source rock.
