Structural plays in Ellesmerian sequence and correlative strata of the National Petroleum Reserve, Alaska
Year: 2003
Type: report
Abstract: the footwall below the basal detachment for most early Tertiary thrusting.Because these traps lie beneath the main source rock units (Shublik, Kingak, lower Brookian sequence), reservoirs that are juxtaposed by faulting against source-rock units are expected to have the most favorable migration pathways.The charge will be primarily remigrated gas; no oil is expected because of the great depths (15,000 to 26,000 ft) and consequent high thermal maturity of this play.Although the the probability of charge and timeliness of trap formation and gas remigration are excellent, seal and reservoir qualities are anticipated to be poor.Our analysis suggests that about 2.0 TCF of techncially recoverable gas can be expected in the play.
