ANTEC at NPE: Editors' Picks

One of the unusual features of NPE 2009 in Chicago June 22-24 will be the first-ever concurrent presentation of the SPE ANTEC conference, by far the largest of seven conferences at McCormick Place during the show.

One of the unusual features of NPE 2009 in Chicago June 22-24 will be the first-ever concurrent presentation of the SPE ANTEC conference, by far the largest of seven conferences at McCormick Place during the show. ANTEC, presented with financial support from Dow Chemical Co., will have a record 750 papers and interactive poster sessions. Our editors selected a handful of papers that address timely and newsworthy topics. Conference sessions are indicated by numbers and letters for the day of the week. (INT designates interactive sessions on Tues., June 23.) Access complete abstracts of the papers at
