The SPE A Peer Apart award recognizes those dedicated individuals involved in the review of 100 or more papers for SPE Journal.
Peer review is an essential part of scientific publishing and helps to ensure the information contained in a journal is well supported and clearly articulated. Volunteers who commit their time to reviewing papers make substantial contributions to the technical excellence of our industry’s literature. Each year, SPE typically draws on the expertise of more than 1,400 reviewers who contribute over 3,500 reviews for SPE Journal. These committed volunteers come from a variety of backgrounds, including academia, service and operator companies, and consultancies from around the world.
Peer review is a demanding and time-consuming task. Over time, the individuals receiving this honor have volunteered hundreds of hours to the Society, making SPE journals a valuable resource to authors and the industry. It is an outstanding accomplishment for those who reach the milestone of reviewing 100 papers.
This year, 11 individuals joined this elite group, bringing the total number of A Peer Apart honorees to 246 dedicated members.
Please join us in congratulating the 2026 honorees.
