About NFLSS


The National Fluids Lease Sale System (NFLSS) supports the BLM administration of the leasing program for Federal onshore oil and gas and geothermal leasing. Four key objectives of the new system are to: (1) provide efficiencies in the Expression of Interest (EOI) submission process, (2) shorten the time required to prepare for an upcoming lease sale, (3) enable real-time reporting capabilities, and (4) extend protest management capabilities of the bureau.


This web-based system serves as a powerful and flexible assistant in the leasing workflow process. In addition to interfacing with the Legacy Rehost 2000 (LR2000) system and available spatial applications, the NFLSS will assist the BLM state offices in managing pertinent surface use stipulations.


Key features of the NFLSS web application include:

  • Intuitive, user-friendly interface
  • Advanced search capabilities to provide rapid access to leasing data
  • Enhanced Reporting
  • Integration with existing bureau systems
  • Quick Links to Key BLM and DOI Resources
  • Role-based access control
  • Section 508 compliance
  • Robust Document Management capabilities that leverage metadata
  • New task management functionality
  • More transparency of leasing activities for the general public
  • Information Security
  • Central management of leasing data to facilitate reporting at the national level, and
  • Future integration with powerful GIS mapping tools.

The system is comprised of an internal web application, used by the BLM staff, and a public-facing portal, which allows members of the public to electronically submit EOIs via the online form and track the status of their EOIs through their lifecycle. The BLM staff (who are authenticated users) use the system to research and evaluate eligible lands that are available for leasing, as well as prepare parcels for upcoming lease sales.


The new functionality that this system provides for the public user, as well as the BLM staff that participate in business workflows, increases the efficiency of the leasing program and allows the bureau to provide better service to the public.


An integrated product team that provided critical input into the design of this system was comprised of representatives from several state offices, including California, Colorado, Eastern States, Utah, New Mexico, Montana, Nevada and Wyoming; the Washington Office; the BLM National Operations Center, Division of Information Resource Management; and an experienced application development team. The NFLSS project is employing Agile/scrum methodologies to rapidly produce application features.
