This November 2006 issue of this journal brings my tenure as Executive
Editor to an end. The 2-year term has passed very quickly and, while the role
has been demanding, it has also been a lot of fun. Norm Warpinski will be
taking over as Executive Editor; I am sure you will give him your full
Along with the announcement of my successor, we also recognized the
outstanding Technical Editors for SPEPO at our annual committee meeting
held in San Antonio. This year our Outstanding Technical Editors are Mahmoud
Asadi, Peter Clark,Yong Fan, Phillip Harris,Charles Hinrichsen, Robert
Holtslag,Myles Jordan,Mark Looney,Jennifer Miskimins,Jorge Pinedo,Jose Solares,
andDiederik van Batenburg. Congratulations to each of you for achieving this
special recognition. I appreciate the time and effort each Technical Editor
volunteers to SPE in the peer-review process. Without their help, SPE would be
unable to publish its technical journals.
After this issue of SPEPO, there will be a number of changes in the
Editorial Review Committee. Bill Bailey and Elise Striz will retire after
completing their term as Review Chairpersons. I want to personally thank both
of them for their outstanding service to SPEPO as Review Chairs and the
assistance they provided me during this period as well. Thanks, Bill and
As Bill and Elise step down, we have two new Review Chairs coming
aboard. Jennifer Miskimins and Joe Smith will join Harold Brannon, Ian
Collins, Ali Ghalambor, and Dean Wehunt as Review Chairs during the coming
year. I want to thank each of you for your willingness to serve SPE in the
important function of Review Chair.
I also want to recognize two individuals—Stacie Hughes and Shashana
Pearson-Hormillosa—who have played a very important role in producing
SPEPO during the past 2 years. Without their assistance, this journal
could never be published. I want to thank both of you for your outstanding
support. Without your help, I would have never accomplished the things I did
during my tenure as Executive Editor. I will miss working with you. Thank
Last, but not least, I want to thank you, the readers of SPEPO. You
are the reason we publish, and I trust we have met your expectation over the
past 2 years.
Leading off this issue, a scale paper. The Comparison of Nonaqueous and
Aqueous Scale-Inhibitor Treatments: Experimental and Modeling Studies
describes results from a series of comparative corefloods and static
compatibility tests examining the differences in laboratory-test procedure,
scale-inhibitor returns, and modeling approaches for nonaqueous and aqueous
The next paper, Sanding: A Rigorous Examination of the Interplay Between
Drawdown, Depletion, Startup Frequency, and Water Cut, describes factors
and mechanisms leading to sanding within an integrated-rock and soil-mechanics
framework. The proposed approach is used in discussing sanding at several wells
in two different fields.
Perforating multiple pay intervals to achieve optimum treatment coverage has
long been a topic of considerable debate. The paper, Unique Multistage
Process Allows Pinpoint Treatment of Hard-To-Reach Pay, describes a new
multistage perforating technique known as “external casing perforating.” This
technique allows the operator to perforate and isolate zones in as little as 30
minutes between treatment stages. As many as 17 discrete intervals have
successfully been treated within a 24-hour period.
Use of Viscoelastic-Surfactant-Based Diverting Agents for Acid
Stimulation: Case Histories in GOM presents several case histories of
viscoelastic-surfactant-diverting applications in the Gulf of Mexico (GOM),
including acidizing before frac packing and remedial treatment of frac-packed
Real-Time Optimization: Classification and Assessment focuses on the
classification of real-time optimization (RTO) technology categories, lessons
learned from industry experience, the perceived value of RTO initiatives, and a
screening guide based on case histories.
Use of Nitrate To Mitigate Reservoir Souring in Bonga Deepwater,
Development Offshore Nigeria presents a detailed evaluation of the
potential for biogenic reservoir souring and work done to predict
H2S levels. The selection of nitrate as a mitigation method is also
Liquid loading is a serious problem in mature gas fields. The paper
Numerical and Analytical Modeling of the Gas-Well Liquid-Loading Process
provides the analysis of production behavior of liquid-loaded wells over time.
The data show that these wells can operate at two different rates: a stable
rate at which full production is taking place, and a lower, metastable rate at
which liquid-loading effects play a role.
From Precommissioning to Startup: Getting Chemical Injection Right
details the lessons learned from practical field experiences concerning the
design, construction, and commissioning of a production-chemical program for a
new field development.
The final paper in this issue, Survival Analysis: The Statistically
Rigorous Method for Analyzing Electrical-Submersible-Pump System
Performance, presents a rigorous statistical methodology to analyze
electrical-submersible-pump (ESP) system-performance data. The approach
extracts unbiased information from performance data and permits lifetime
modeling by use of parameter combinations employing all available data. The
methodology was applied to a data set pertaining to an ESP system in Ecuador
and to a much larger worldwide data set. Many questions related to ESP system
performance can now be answered.
