Executive Summary

Welcome to the August 2019 issue of SPE Production & Operations. One of the most interesting and rewarding aspects of being the executive editor for this journal is that I have the opportunity to read about all domains with the production and operations disciplines. Of course, every reader has the same chance, but most of us rarely or almost never read papers that are not within our own area of expertise. As the executive editor, however, I am sometimes forced to review articles that are written on topics on which I have never worked. This is actually better than it sounds because I can appreciate the vast variety of processes required to extract hydrocarbon from the surface. The further humbling fact is that we are not even taking into account drilling, reservoir, geology, and other areas beyond our imagination. It is the effort of a tremendous number of people over a long history that allows us to enjoy this energy. In the last issue, I encouraged readers to jump out of their comfort zone every once in a while to read about subjects with which they are not technically comfortable. This time I would like to share some thoughts with authors so that they can help readers outside of their technical domain gain good experiences reading their papers.

Papers published in SPE Production & Operations may result from a variety of purposes depending on the authors’ aspiration. Some link their work with the existing literature for a continued progression in the state of the technologies; some compare and differentiate their own work from that of others to expand the solutions on certain problems; and some document their work as a history of the technology evolution. From a reader’s perspective, especially a reader who is new to a certain area or who wants to be informed about broader technical areas of production processes, trying to gain desired information can be daunting or satisfying. Hence, the authors have the power—and responsibility—to make the reader’s experience as good as possible.

There are plenty of excellent papers published in this issue, but I would like to mention two examples that were enjoyable for me to read for the simple reason that they are related to facility and equipment, which are completely out of my area of expertise: Production-Facility Emissions Reduction in Liquid-Rich Shales: An Update and Computational and Experimental Study of Sand Entrapment in a Hydrocyclone During Desanding Operations in Oil Fields: Consequences for Leakage and Separation Efficiency. The authors of these papers describe the problem, illustrate the solution, and document the technical merit in a very easy-to-understand manner and include laboratory work, quantitative analyses, and field studies. I found that with basic engineering and mathematics knowledge, I could read through the paper without getting lost quickly in the equations or getting bored by lengthy undue literature reviews. I often think that in the publication business, authors can take the approach of readers being their clients. It is when people other than the authors themselves enjoy to read and can get the usefulness out of it that the paper becomes more beneficial and publishable.

There are four main technical topics published in this issue of the journal, including Optimizing Production Operation, Surface Facility and Equipment, Formation Damage and Stimulation, and Fluid Flow in Pipes. I hope you enjoy reading them.
