Conventional Oil and Gas Plays in Central Alaska from 1995 National Assessment

Central Alaska province contains mapped geologic boundaries for five conventional oil and gas plays defined for the 1995 U.S. National Oil and Gas Assessment. The dataset includes play numbers and names, such as 'Central Alaska Cenozoic Gas' and 'Kandik Upper Cretaceous and Tertiary Non-Marine Strata'. Boundaries were defined by geologists for each province between 1993 and 1994, with data published by CEOS_EXTRA.

Use Cases

• Map the spatial extent of the 'Central Alaska Paleozoic Oil' play boundary for regional geologic studies.
• Analyze the distribution of five named plays, like 'Kandik Pre-Mid-Cretaceous Strata', across the Central Alaska province.
• Use the play number and name fields to cross-reference 1995 assessment results with other geologic datasets.

Strengths

• Defines boundaries for five distinct conventional oil and gas plays.
• Play boundaries were defined geologically by subject matter experts between 1993-1994.

Limitations

• Dataset is from a 1995 assessment and does not reflect discoveries or geologic understanding after that date.
• No quantitative resource estimates, well data, or reservoir properties are included with the boundary files.
• Limited to only the Central Alaska province (province 2) and five specific plays.
