The administration of President Donald Trump plans to unveil a budget proposal 

Tuesday that will call for selling half of the US' crude from the Strategic Petroleum 

Reserve, a plan it says will cut the federal deficit by $16.6 billion, according to the 

White House. 

The proposed fiscal 2018 budget, which will be delivered to the House and Senate 

this morning, is not expected to be approved by Congress, but is seen as a roadm

ap for the administration's policy goals. 

 An  outline of the budget proposal calls for reducing the SPR "by half" and claims 

sales over 10 years would raise $16.6 billion. 

 As of Friday, the SPR held 687.7 million barrels of crude, including 259.8 million b

arrels of sweet crude and 427.9 million barrels of sour crude, according to the Dep

artment of Energy, which manages the reserve. 

In March, DOE sold 10 million barrels of crude from the SPR, the first of a total of 2

5 million barrels mandated for sale to help pay for a biomedical research bill signed 

into law in December. 

In February, DOE sold 6.4 million barrels for $344.8 million as part of a sale authori

zed by Congress to partially fund an effort to modernize the SPR and add marine te

rminal capacity. DOE plans to sell a total of $2 billion SPR crude oil to pay for mode

rnization and new marine capacity. 

In addition to the 25 million barrels to be sold for the biomedical law, Congress has 

approved a federal budget and transportation bill that will all partially be funded by 

sales of a combined 124 million SPR barrels.
