The Midstream Business annual rankings of the sector’s largest natural gas and NGL processors for calendar year 2016 were a study in contrasts. In both cases familiar names continued to top the charts.

But for gas processing, all of them changed places—some moving up the league table, some moving lower. For most companies, reported volumes of throughput were slightly lower, so changes in ranking were largely a matter of holding to smaller decreases.

In contrast, the NGL production table was steady-on with the same companies in the same order. Gains and losses in liquids production were more variable than in gas processing, but in no case was the difference enough to appreciably shuffle the standings. And in both tables, the second set of companies, ranked six through 10, stayed in the same relative order, again with some closing or widening gaps.
