Why was the data set created?

To delineate the centerpoint locations of and primary commodity produced by oil and gas fields in Open File Report 97-470F Maps Showing Geology, Geologic Provinces, and Oil and Gas Fields of the Asia Pacific Region; Plate 1: The Far East, which is being compiled as a reference for the U.S. Geological Survey's World Energy Project assessment of undiscovered, technically recoverable oil and gas resources of the world. This coverage is used to produce a map and an Adobe Acrobat Portable Document of the map to be published on CD-ROM. An Arcview shapefile derived from this coverage is used in an Arcview project and an ArcExplorer project.

How was the data set created?

1. From what previous works were the data drawn?

   PCI (source 1 of 1)

   Petroconsultants International Data Corp., 19960000, Petroconsultants Exploration and Production Database.

   Type_of_Source_Media: CD-ROM

   Source_Contribution:

   Location of oil and gas field centerpoints, Country of location, Primary commodity produced.

2. How were the data generated, processed, and modified?

   Date: 15-Jan-1999 (process 1 of 4)

   Data is censored by deleting sensitive fields of proprietary data containing intellectual property of Petroconsultants International Data Corp.

   Date: 15-Jan-1999 (process 2 of 4)

   A point coverage is generated in Arc/Info using latitude and longitude coordinates of field centerpoints from database.

   Date: 15-Jan-1999 (process 3 of 4)

   The point coverage is projected to the current Lambert projection in Arc/Info

   Date: 15-Jan-1999 (process 4 of 4)

   Point coverage is clipped to the current extent in Arc/Info

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

   All attributes except Primary Commodity Produced and Country in which field lies have been removed. Accuracy depends upon the original Petroconsultants data.

2. How accurate are the geographic locations?

   Dependent upon original Petroconsultants data.

3. How accurate are the heights or depths?

   Not Applicable

4. Where are the gaps in the data? What is missing?

   This data set contains the centerpoint locations of oil and gas fields from the Petroconsultants International Data Corp. Petroleum Exploration and Production Database, 1996. The points are generated from the latitude and longitude coordinates in the data base.

5. How consistent are the relationships among the observations, including topology?

   Points are not duplicated and are attributed.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: None

Use_Constraints:

Contains intellectual property of Petroconsultants International Data Corp.
