16 gru 2021 · The formation, according to the report, “has the potential to revitalize the San Juan Basin with both oil and natural gas production.” In a separate USGS report, a rough estimate showed there could be 27 trillion cubic feet of recoverable natural gas in the Mancos Shale.
2 cze 2021 · The “Offshore Mancos Shale play” targets shales and shaly sandstones, including both low-quality reservoir rocks and Type II-III source rocks. As such, it is best described as a hybrid play. Figure 3 Oil (green) and gas (red) wells drilled in Mancos pools.
16 cze 2024 · The Mancos Shale also has a significant amount of variability across the oily and gassy windows of the San Juan, Dixon said. There are significant challenges to unlocking the San Juan’s oil window, but the prize of low-cost inventory might be worth the effort.
8 cze 2016 · The Mancos Shale in the Piceance Basin of Colorado contains an estimated mean of 66 trillion cubic feet of shale natural gas, 74 million barrels of shale oil and 45 million barrels of natural gas liquids, according to an updated assessment by the U.S. Geological Survey.
2 lip 2018 · The Upper Mancos has been productive of oil and natural gas from sandstones and shales. The Upper Mancos Shale contains three plays: the Tocito marine bar play, the Naturally fractured Mancos shale play, and the Offshore Mancos shale play. The Tocito play is a conventional oil play productive from sandstones in the lower part of the Upper Mancos.
11 sie 2022 · Historically, the Offshore Mancos play of the San Juan Basin has produced oil from noncommercial to marginally commercial reservoirs formed by dark-gray marine shale with thin beds and laminae of fine-grained sandstone of limited permeability.
The greatest potential for new production on the Navajo Reservation is in the overlying Mancos shale. It was deposited as the Cretaceous seaway inundated the area depositing over 1,500 feet of marine shale in the basin (Figure 5 is a paleomap of New Mexico and surrounding areas during Cretaceous time).
