Executive Summary

Welcome to the May 2020 issue of SPE Production & Operations. The global COVID-19 pandemic has unprecedentedly affected the way we live. While the duration of the impact is unknown, one thing we can foresee for our industry is that a storm of funding and, more unfortunately, job cuts are on the way. On the bright side, the broad work-from-home practice has given us an opportunity to taste the future work environment of the digital world. Though net meeting and webcasting have been used frequently before this time, the effectiveness and technical issues have always been problematic. We can expect the technology advancement in this area to accelerate to deliver flawless virtual conference and even virtual office. The cost reduction and broader information broadcast can benefit both employers and employees when the technologies are effectively applied.

How are the new and expanded communication technologies going to impact SPE publications? This is the main thing in my mind during the writing of this executive summary. Here are a few of my thoughts:


1.     Traditionally, SPE journal papers originate as conference papers. A benefit of conference papers moving to SPE peer review is that the conference papers have gone through a certain degree of review, at least the abstract, by the conference technical committees, which consist of technical experts. Hence, the topics and qualities have been screened somewhat. Conferences need tremendous resources and time to organize. Since March, nearly all the conferences throughout the world have been cancelled or postponed. The efforts of the staff, organizing committees, and authors are unfulfilled. I am thinking what if mid-scaled virtual conferences can become reality and be held more frequently, with less preparation efforts by the organizers. Technical presentations can be based on abstract only, and, overall, more technical information exchanges can take place this way. Maybe SPE journals can invite authors to write full papers based on presentation audience feedback.       

2.     In recent years, there have been more and more papers submitted for direct peer review. This trend most likely will continue. This is another route authors can take to showcase their work when conferences are not available. It is always a good idea for the authors who submit directly to the peer review process to clearly understand which journal is most suitable for their paper, not only in the technical area but also in the scope of the content. For SPE Production & Operations specifically, “operation” is a key important word. Real data supported by case studies or sound experimental procedures are always welcome or preferred. This can prevent author’s frustration of unnecessary rejection.
