Expressions of Interest in Oil and Gas Leasing

An Expression of Interest (EOI) is an informal nomination to request that certain lands be included in an oil and gas competitive lease sale. This request must be made in writing (no specific form required) to the BLM State Office having jurisdiction over the lands. No filing fee or rental is required with an EOI. EOIs are not automatically placed on a sale when received. The parcels must be reviewed for availability and environmental concerns prior to being placed on a sale. Additionally, if your EOI includes lands where the surface is managed by another agency, BLM is required to obtain approval and recommendations from that surface managing agency (SMA) prior to placing the lands on a competitive lease sale notice.  The SMA may need to prepare or update its environmental document, which may require additional time.  In accordance with Leasing Reform IM 2010-117, the BLM is required to post notice of Competitive Sale 90 days prior to the sale. The oil and gas plats also must be notated with the parcels 90 days prior to the sale. The BLM will post sale notices in the BLM California State Office Information Access Center (IAC) and online at:

Per Washington Office Instruction Memorandum No. 2014-004, effective 10/01/2013, The BLM will publish EOI submissions received on or after January 1, 2014, on the website of the BLM state office where the nominated parcel is located. EOI submitters who consider their name and address confidential should not include that information in their EOI. The BLM no longer requires submitters of EOIs to provide their name or address. Submitters may still provide this information for contact purposes; however, the BLM will make this information available to the public. Expressions of Interest Received.

EOI for Split Estate: Anyone submitting an EOI, which includes split estate lands (private surface/Federal minerals), must provide the name and address of the current private surface owner(s). Whenever a split estate parcel is included in an oil and gas Notice of Competitive Lease Sale, the BLM will send a courtesy letter to the surface owner(s). The letter will provide the surface owner(s) notice of the scheduled competitive lease sale as well as information about the BLM’s regulations and procedures for Federal oil and gas leasing and development on split estate lands. If the EOI does not provide the name and address of the surface owner(s), it will not be processed by the BLM, and such lands will not be placed on a list of lands included in a Notice of Competitive Lease Sale.

Regulations pertaining to competitive leasing can be found at 43 Code of Federal Regulations (CFR) 3120. Prior to submitting your EOI, BLM public records should be reviewed to make certain the lands are available for leasing.  Include a complete legal land description, Township, Range, Section, County, Acreage, describe by aliquot part (NENW) if applicable. Please verify that the U.S. owns the minerals to lease and separate your parcels by Public Domain lands and Acquired lands. If your EOI contains lands not within a 6-mile square area, please configure the lands into the parcels as you would like to see them on a sale notice. Parcels will not exceed 2,560.00 acres on the sale notice, so if your EOI contains more than 2,560.00 acres and you have not configured or prioritized your parcels, BLM will parcel the lands, which may not agree with the parcel configuration you prefer.

 Some lands not available for leasing, but not limited to are:
  • Lands already leased for oil and gas
  • Lands with non-Federally owned minerals
  • Lands within city limits
  • Lands withdrawn from mineral leasing
  • Lands located in designated or proposed wilderness areas (WSA/DWA)
  • Lands within an Indian Reservation
  • Lands with pending mineral entry applications
  • Lands with patented mining claims
  • Lands offered for sale within the last two years
In checking the public records, make certain that:
  • Expired leases have not been extended beyond their expiration date by diligent drilling and
  • Terminated leases are not in the process of being reinstated.

Submit a written request (letter format) with the following information to:
                 Bureau of Land Management
                 Attn: Branch of Minerals
                 2400 Cottage Way Suite W-1623 
                 Sacramento, CA 95815
