Exploration history, north US Atlantic Margin
The Baltimore Canyon Trough is the site of 26 exploration wells and 2 stratigraphic tests. As of Nov. 1981, 6 dry holes had been drilled on the Great Stone Dome. This structure appeared to be the largest and most promising in the basin. Seventeen wells have been drilled along the edge of the continental shelf with significant hydrocarbon shows reported from 5 wells. Combined daily flow rate is 90 mmcf. Georges Bank Basin is characterized by an older thick carbonate and evaporite sequence (0 to 8 km) of late Triassic-early Jurassic age; a middle sequence of interbedded limestone, sandstone, mudstone, and red shale of middle Jurassic to early Cretaceous age (0 to 2.5 km); and a thin sequence (middle Cretaceous and younger) of transgressive shelf limestone and regressive claystone and siltstone (0.5 to 2 km). Elevated patch reefs beneath the shelf and a massive reeflike carbonate buildup under the slope form potential hydrocarbon traps.
