Frac spread margins continue to rise, due to increased NGL prices and decreased natural gas values at Conway and flat feedstock prices at Mont Belvieu.
The most improved margin to fractionate at both hubs was for C5+, which improved 30% to 30¢/gal at Mont Belvieu and 31% to 43¢/gal at Conway. Despite these improvements, iso-butane remains the most profitable NGL to fractionate at both hubs.
