Enefit American Oil
company based in USA, subsidiary of Eesti Energia

Enefit American Oil (former name: Oil Shale Exploration Company - OSEC) is a Utah-based oil shale exploration and development company. It has been involved in the development of oil shale since 2005. Since 2011 it is a subsidiary of Eesti Energia, internationally known as Enefit. In January 2024 Eesti Energia announced that it will cease all its operations in the United States.
History
OSEC was formed in 2005 as a limited liability company by following companies:
L&R Energy, Inc.
Twin Pines Coal Company
Shale Investments, LLC
In 2008, OSEC concluded a contract with Brazilian oil company Petrobras and Japanese investment and trading company Mitsui according to which Petrobras and Misui had a right to acquire 10%-20% interests each in an oil shale joint venture with OSEC.
In March 2011, Estonian energy company Eesti Energia acquired 100% of OSEC's shares. This transaction was criticized by some Estonian oil shale scientists who expressed doubts if the Eesti Energia's Enefit extraction technology is suitable Utah oil shale due to the high percentage of nitrous compounds in it.
In January 2024 Eesti Energia announced that it will cease all operations in the United States and will liquidate four of its U.S. subsidiaries.
Operations
Enefit American Oil owns or leases 30,274 acres (122.51 km2) of oil shale property in the Uintah Basin in Utah, containing an estimated 2.6 billion barrels (410×10^6 m3) of recoverable shale oil. It also leases from the United States Bureau of Land Management the abandoned White River Oil Shale Mine 45 miles (72 km) southeast of Vernal, Utah.

Why this record matters
The subject matters to the history & society register because the source frames it as company based in USA, subsidiary of Eesti Energia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q5376726. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2005, 2011, 2024 and 2008.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
