This product resulted from merging four regional datasets containing BOEM Planning Area outlines. The use of these Planning Areas makes it easier to refer to Official Protraction Diagrams (OPD) and individual blocks within a region. The Submerged Lands Act (SLA) boundary, along with the Continental Shelf Boundary (CSB), the Limit of Protraction were used to complete the polygons for the Planning Areas. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are considered to be approximate and are NOT an OFFICIAL record for the exact block coordinates or areas. The Official Protraction Diagrams (OPDs) and Supplemental Official OCS Block Diagrams (SOBDs) serve as the legal definition for BOEM offshore boundary coordinates and area descriptions. If any discrepancies are found between these shapefiles and the OPDs and SOBDs, it is the OPD and SOBD diagrams which take precedence. The original datasets were developed in UTM. Here they are projected in WGS_1984_World_Mercator. As a result, any area values computed from this dataset may differ from the official BOEM areas.

These data show the location of oil and gas wells within U.S. and territorial waters. The values of an oil and gas well record can change considerably over time, and with varied ownership, and with the jurisdiction that the well is located within. The fields in this data set are only a subset of the most common values available.

This data set contains Official Protraction Diagram (OPD) outlines in ESRI Arc/Info export and Arc/View shape file formats for the BOEM Pacific Region. The use of OPD s makes it easier to refer to individual blocks within a region or planning area. Further information on the historic development of OPD s can be found in OCS Report BOEM 99-0006: Boundary Development on the Outer Continental Shelf. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for the exact OPD boundaries. Only the paper OPD or a digital image of them serve as OFFICIAL records.

This point layer represents approximate locations of Marine Oil Terminals that are regulated by the California State Lands Commission. Most terminal points were collected with Collector for ArcGIS, but some were approximated by other means. The California State Lands Commission makes no warranty as to the accuracy of this data nor assumes any liability for its use. This information is subject to change.

This data set contains Official Protraction Diagram (OPD) outlines in ESRI Arc/Info export and Arc/View shape file formats for the BOEM Pacific Region. The use of OPD s makes it easier to refer to individual blocks within a region or planning area. Further information on the SLA and development of this line from baseline points can be found in OCS Report BOEM 99-0006: Boundary Development on the Outer Continental Shelf. https://www.boem.gov/BOEM-Newsroom/Library/Publications/1999/99-0006-pdf.aspx These OPD diagrams were clipped along the Submerged Lands Act (SLA) boundary and along lines contained in the Continental Shelf Boundaries (CSB) GIS data files to show only those blocks or portions thereof within federal jurisdiction. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for the exact OPD boundaries. Only the paper OPD or a digital image of them serve as OFFICIAL records.

This data set contains Outer Continental Shelf block outlines in ArcGIS shape file format for the BOEM Pacific Region. OCS blocks are used to define small geographic areas within an Official Protraction Diagram (OPD) for leasing and administrative purposes. These blocks have been clipped along the Submerged Lands Act (SLA) boundary and along the Continental Shelf Boundaries. Additional details are available from: https://www.boem.gov/BOEM-Newsroom/Library/Publications/1999/99-0006-pdf.aspx Because GIS projection and topology functions can change or generalize coordinates, and because shape files can not represent true arcs, these GIS files are considered to be approximate and are NOT an OFFICIAL record for the exact block coordinates or areas. The Official Protraction Diagrams (OPDs) and Supplemental Official Block Diagrams (SOBDs) serve as the legal definition for BOEM offshore boundary coordinates and area descriptions.

These data show the location of probable oil or gas geologic structures (plays) mapped within the outer continental shelf of the United States. Plays are groups of known or postulated subsurface hydrocarbon accumulations that share common geologic, geographic, and temporal properties, such as history of hydrocarbon generation, migration, reservoir development, and entrapment. Seismic surveys were used to analyze the Unrecovered Technically Recoverable Resource. Plays are displayed as two-dimensional features, but may overlap vertically allowing for multiple plays in the same area.
