Title: Oil and Gas Units

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:

This data set contains the oil and gas units, derived from Legal land Descriptions (LLD) contained in the US Bureau of Land Management LR2000 Database, and geocoded (mapped) using the Public Land Survey System (PLSS) / Geographic Coordinate Data Base (GCDB) derived from the most accurate survey data available through BLM Cadastral Survey workforce, and the Premier Data Systems CarteView software.

Purpose: To identify oil and gas units.

Attribute_Accuracy_Report:

The GIS data is created from the LR2000 data base quartely. Data is processed using the most current GCDB data (Survey Grid) and the LR2000 database legal land descriptions for Oil and Gas Units using the CarteView software program which matches LLD descriptions to GCDB features. Some polygons are not processed due to the lack of GCDB data and/or complex legal descriptions that do not match or "Exclude" certain areas like Right-of-Ways or Reservoirs. Any records not process are written to a errors .txt file. The error file is included with this data set so that the user can see what records did not process. If the user of this data is familiar with legal descriptions they could manually create the missing geometry and attributes for the GIS layer. BLM Colorado does not always process missing records from the error file in this GIS layer due to time contraints and man hour limits.

Horizontal_Positional_Accuracy_Report:

The LR2000 database is a flat file that is updated daily by BLM specialist's. It contains all ot the attribute fields that describe what the data is and where the data is in relation to Meridian, Township, Range, Section, etc..., one of the attribute fields is a Legal Land Description. When BLM runs the LR2000 database against the GCDB survey grid the software generates polygons based on what the LR2000 database Legal Land Description is and how well it matches with the GCDB Land Grid. There are known errors in the LR2000 database and there are also problem areas or areas that are incomplete in the GCDB Land Grid. Both of these source documents are being updated and improved on as time goes by. A flat file (error file) is generated during this process that hold all of the records that did not process. The error file is part of the dataset and should be used by the user of this data to identify polygons that did not generate.

Title: Case recordization data base

Source_Citation_Abbreviation: BLM Case Rec

Source_Contribution:

Oil and Gas Units from the BLM Case Recordation database. The database provides the attribute information and the legal description of the units, used to geocode the locations onto a map. GIS data is processed quarterly from LR2000 database.

Source_Information:

Source_Citation_Abbreviation: BLM Geographic Coordinate Data Base (GCDB)

Source_Contribution:

The accuracy and precision of the landgrid determines the spatial accuracy and precision of t he final location of the geometry in this GIS layer.

Process_Step:

Process_Description:

Oil and gas units are extracted from the BLM Case Recordation database using the standard "Oil & Gas Units" query in Premier Data Service's PDS Studio software. The leases are run through Premier Data Service's LotFinder software to increase the precision of the lease locations.

Process_Date: Updated Quarterly

Process_Step:

Process_Description:

Premier Data Service's CarteView software is used to convert the lease locations from a legal description to map coordinates. The best available landgrid is used for the geocoding. BLM's GCDB data is used for the landgrid layer.
