Since exploration drilling began on the North Slope of Alaska in 1944, numerous oil and gas accumulations have been discovered and 18 billion barrels of liquid hydrocarbons have been produced from North Alaska through 2018. Wells have targeted five main play types: Ellesmerian clastics and carbonates (Kekiktuk, Lisburne, Ivishak, Shublik, and Sag River), Jurassic shoreface sands (Barrow, Simpson, Kugrua, Nechelik, Nuiqsut, and Alpine), Cretaceous rift sands (Walakpa, Kuparuk, Put River, Kemik, and Thomson), Brookian turbidites (Torok, Seabee, and Canning), and Brookian topsets (Nanushuk, Tuluvak, Schrader Bluff, West Sak, Ugnu, Prince Creek, and Sagavanirktok). A sixth category called 'Other' includes the remaining targets (e.g., basement, methane hydrates, and coalbed methane). This comprehensive study documents the drilling target by play type from public domain sources for 548 exploration wells on the North Slope and adjacent offshore areas in the Beaufort Sea and Chukchi Sea. The discovery well and production data for each producing pool are integrated into the study. All files are available from the DGGS website: http://doi.org/10.14509/30579. Purpose: The DGGS Energy Resources Section generates new, unbiased information on the geologic framework of frontier areas in Alaska that may host undiscovered oil, gas, coal, and geothermal resources. Northern Alaska is a world-class petroleum province that includes some of North America's most prospective onshore regions. Despite this potential, the North Slope remains underexplored relative to other sedimentary basins around the world. New exploration ventures are hampered by the limited amount of published geologic data, and much of the available information is reconnaissance in nature. This comprehensive study documents the drilling target by play type from public domain sources for 548 exploration wells on the North Slope and adjacent offshore areas in Beaufort and Chukchi Seas.

Data_Set_Credit: The authors gratefully acknowledge Kelsey Anderson and Joseph Skutca for their early contributions to the exploration target research in NPRA and state lease sale regions. The authors also gratefully acknowledge Kirk Sherwood for guiding us through the federal data request process for Outer Continental Shelf (OCS) well data. Significant improvements were made to the map from feedback and discussions with Kirk Sherwood, Paul Decker, Don Krouskop, Steve Moothart, Kevin Frank, Dan Seamount, Steve Davies, Meredith Guhl, David Boyer, Jhonny Meza, and Maduabuchi (Pascal) Umekwe. The map benefited from cartographic expertise provided by Sean Conlon and Marta Mueller. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The analyses reported here reflect the protocols and uncertainties described in the accompanying report. Inferences and information presented in this compilation relied upon publicly available well histories (as of 2018) as well as the formation picks available at the Alaska Division of Geological & Geophysical Surveys Geologic Materials Center. For this reason, the database may be missing exploration drilling targets that the operator identified as an objective but did not report in publicly available records. Logical_Consistency_Report: Not applicable Completeness_Report: This publication is a DGGS Miscellaneous Publication (MP). The MP series is intended for reports that provide compilations of previously published information. The data and interpretations have been reviewed by several scientists familiar with the geologic context. This data release is complete but limited to publically available information posted before 2018. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Well location coordinates were pulled from Alaska Oil and Gas Conservation Commission (AOGCC), Alaska Division of Oil and Gas, and Bureau of Ocean Energy Management (BOEM) databases. Well locations utilized in this compilation are derived from the AOGCC calculated bottom hole locations (BHL) unless BHL values were not reported in the source data. In cases with unknown BHL values, we used AOGCC surface hole locations (SHL) or location coordinates provided by BOEM. The AOGCC database provides locations using the NAD27 geographic coordinate system. The authors converted coordinate values to NAD83, State Plane, Zone 4 to facilitate map cartography. Data reprojection introduced small geographic offsets between this dataset and the source data. Given the regional extent of this work, these offsets are inconsequential relative to the overall findings. Lineage: Process_Step: Process_Description: Source information - All exploration target data integrated into this study are from public sources. The primary public domain data sources are state and federal well histories, Alaska Division of Oil and Gas (DOG) unit decisions, Petroleum News articles, Alaska industry news articles, federal well summary reports, and lessee press releases. The authors used an iterative process to collect and review exploration target data. The first step was to gather exploration target information from any possible public source, document the findings, and record a link and page number(s) of where the exploration target data are stated. Then, the authors verified each exploration target and cited the reference. If the target was directly stated or the inferred target could be deduced from the supporting public data, the target was placed into a play type category. Otherwise, the authors conducted an additional search of public data so a satisfactory drilling target could be identified or inferred. Well location coordinates were pulled from Alaska Oil and Gas Conservation Commission (AOGCC), Alaska Division of Oil and Gas, and Bureau of Ocean Energy Management (BOEM) databases. Well locations utilized in this compilation are derived from the AOGCC calculated bottom hole locations (BHL) unless BHL values were not reported in the source data. In cases with unknown BHL values, we used AOGCC surface hole locations (SHL) or location coordinates provided by BOEM. The AOGCC database provides locations using the NAD27 geographic coordinate system. The authors converted coordinate values to NAD83, State Plane, Zone 4.
