After 3 years and 12 executive summaries, this is my final incarnation of
this commentary. I am completing my 3-year appointment as the Executive Editor
(EE) of the SPE Production & Operations journal and handing control
over to the new incoming EE, Dean Wehunt. I have thoroughly enjoyed my time as
the SPEPO journal EE; but, if I’m being honest, I am looking forward to
not having to login to ScholarOne Manuscripts on a daily basis!
It was evident to me from the first day in this position that I was going to
need a lot of help and input from various people, and I would like to take this
opportunity to thank them. From the full-time SPE staff, I wouldn’t have
survived this endeavor without the help and support of Stacie Hughes, who
graciously handled my daily questions and concerns. Thanks also to Jeff
Andrews, who final edits the SPEPO papers, for his sense of humor and
forgiveness of my tardiness with deliverables such as this summary. Glenda
Smith, Rebekah Stacha, and Chris Carpenter, thank you for your help and insight
during the past 3 years.
From the technical side, thank you to all of the SPEPO Associate and
Technical Editors. They are the ones who do the real work and are the reason
SPEPO can provide the high-quality papers that it does on a quarterly
basis. The Associate Editors for SPEPO include John Bagzis, Frank Chang,
Craig Cipolla, Ian Collins, Joyce Holtzclaw, Shauna Noonan, Liang-Biao Ouyang,
and Joseph Smith. I owe these eight people a great deal and want to thank them
for their service and time and the commitment they’ve shown to the journal. It
is through their individual efforts that the average time to publish in
SPEPO is currently 85 days, down from 115 days in 2010 and well within
the SPE Board of Directors goal of 112 days. Additionally, during the past 3
years, we have added more than 155 papers to the peer-reviewed literature in
the area of production and operations. Although the Technical Editors are too
numerous to mention here, their efforts are equally important in contributing
to the quality of the journal, and I’d like to take this opportunity once again
to thank them all for their efforts in this area.
Overall, I’d have to say that serving as the Executive Editor was a very
enjoyable and rewarding experience for me personally, and I encourage you to
consider adding your service to this journal (or one of SPE's other six
peer-reviewed journals) as a Technical Editor or an author or in whatever
capacity you find that suites your time and interests.
This edition of SPEPO contains nine papers for your review. We have
three papers in the area of artificial lift. Review of
Electrical-Submersible-Pump Surging Correlation and Models provides a
review of both correlations and mechanistic model results for
electrical-submersible-pump (ESP) surging behaviors and compares them to
experimental results from a closed loop system containing a 24-stage ESP.
Assessing Gas Lift Capability To Support Asset Design discusses a
multidisciplinary approach to installing a gas lift system in certain Qatar
fields that honors input from all potential stakeholders. The third artificial
lift paper, World's Deepest Through-Tubing Electrical Submersible Pumps,
discusses the deployment of the world’s two deepest through-tubing ESP
installations that were installed inside 7-in. casing.
This edition contains one paper where coiled tubing is the main topic.
Case History: Lessons Learned From Retrieval of Coiled Tubing Stuck by
Massive Hydrate Plug When Well-Testing in an Ultradeep-Water Gas Well in
Mexico provides a case study where a hydrate plus formed while the coiled
tubing was being pulled out of the hole. The steps taken to free the coiled
tubing are discussed, along with the best practices that resulted from the
From the area of liquid loading, New Perspective on Gas-Well Liquid
Loading and Unloading discusses how the conventional idea of droplet flow
reversal does not describe reality, but that film-flow reversal does a better
job of describing actual observations. On the basis of these observations, the
benefits of hydrophobic tubing coatings are also reviewed.
Four papers in the area of stimulation are included in this issue.
Surface-Area vs. Conductivity-Type Fracture Treatments in Shale
Reservoirs provides guidelines for the integration of various data to aid
in choosing between surface-area and conductivity-type
hydraulic-fracturing-treatment designs in shale systems. A new
hydraulic-fracture model that simulates complex hydraulic-fracture propagation
in naturally fractured reservoirs and predicts whether the hydraulic fracture
will cross or terminate at the natural fracture interface is the subject of
Modeling of Hydraulic Fracture Network Propagation in a Naturally Fractured
Formation. Experimental Evaluation of Guar-Fracture-Fluid Filter-Cake
Behavior provides experimental results on the thickness of the polymer-gel
filter cake deposited during the fracturing processes and the yield stress of
the polymer-gel concentrate that accumulates in the fracture. The final paper
in this edition, Damage Mechanisms in Unconventional-Gas-Well Stimulation--A
New Look at an Old Problem, provides simulation results of damage effects
in a low-permeability, unconventional reservoir and the impact these effects
can have on production results.
In conclusion, I would like to thank you, the SPEPO reader, for your
support of the journal during my tenure! I hope you find this edition of the
SPE Production & Operations journal and the included papers
beneficial in your everyday efforts.
