NGL prices rose on the week

According to a presentation by the Midstream Energy Group, the average NGL barrel composition in December 2011 was ~43% ethane, ~28% propane, ~7% normal butane, ~9% isobutane, and ~13% pentanes or heavier hydrocarbons. Using this representative composite barrel, NGL prices were up, closing at $34.45 per barrel on July 5 compared to $35.77 per barrel for the week ended July 12, which is a positive short-term indicator for companies with NGL production. The representative NGL barrel traded as high as ~$39 per barrel in mid March, but since then, prices have largely declined, resulting in a medium-term negative indicator as well
