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.

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.

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.

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.

This data set contains Continental Shelf Boundary (CSB) lines in ESRI Arc/Info export and Arc/View shape file formats for the BOEM Pacific Region. The CSB defines the seaward limit of federally managed OCS lands. This CSB file only includes the lateral boundaries between the United States and Canada or Mexico. That portion of the CSB defined by the 200 nautical mile line has not yet been calculated. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for the exact CSB.

This data set contains boundary lines in ESRI Arc/Info export and Arc/View shape file formats the for Santa Barbara Channel Ecological Preserve and Buffer Zone offshore of Southern California. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for exact ecological preserve boundaries.
