Our oil delivery commitments include commitments with Salt Lake City, Utah refiners. Our delivery commitments are for approximately 18,000 barrels of oil per day through 2020 and an additional 20,000 barrels of oil per day expected to start in 2016 and continuing through 2025. The 20,000 barrel per day delivery commitment represents approximately 7,300 MBbls of our committed oil volumes for each of the years 2016 through 2025. The timing may change due to timing of the refinery expansion completion. These commitments relate to our Uinta Basin production.
