I would like to spend a little of my space discussing references. Looking at
recent papers submitted to Production & Operations, I have noticed that
there are a relatively large number of papers with few or no references.
In my opinion, references serve two primary functions. The first function is
to provide background material for readers who wish to delve deeper into some
aspect of the technology. Since just about everything that we do has been built
on work done before us, providing the pertinent references allows the reader to
follow in the author’s footsteps. Without references, it is often difficult to
understand the technical landscape under which the premise of the paper was
formulated, particularly for readers who are new to the technology.
Secondly, the inclusion of references gives important information to the
more knowledgeable readers. These readers often know what the critical
references are, and if some of those are missing from a paper, you can be sure
that they will be reading the paper with some degree of skepticism. A
demonstration (e.g., the references) that you are aware of the prior work is
often a good way to reassure the reader that you understand the problem
This is to say nothing of the fact that knowledge of prior studies should be
essential for any good research endeavor. One would hope that the authors know
the references, but just failed to provide them.
Lastly, an issue that annoys most readers is the practice of the arrogant
authors who only list their own papers as the references. I understand that
their current paper may be on the basis of work done in earlier studies, but I
also presume that there must be someone else who is working in their area and
has published relevant material. If not, then either the technology does not
have much value, or maybe the author is so far ahead of everybody that we are
actually reading the work of the next Einstein. However, I doubt it is often
Please help out your readers and provide relevant references in your papers.
Not having the important references is a good reason for reviewers to reject
This issue has papers primarily dealing with production analyses, remedial
treatments, and chemistry. We start with real-time optimization and management
papers. Real-Time Production Optimization of Oil and Gas Production Systems:
A Technology Survey is a wide ranging review of real-time production
optimization systems that describes the information flow, optimization, model
updating, and associated challenges in developing such systems. Real-Time
Field Surveillance and Well Services Management in a Large Mature Onshore
Field: Case Study describes the management of real time data, engineering
modeling and remedial work assessment that resulted in improved performance in
Cymric and other oil fields in the San Joaquin oil fields of California.
Analysis and application of production data are the subjects of the next two
papers. An Integrated Technique for Production Data Analysis (PDA) With
Application to Mature Fields discusses Intelligent Production Data
Analysis, which is an integration of decline curve analysis, production data
analysis, and history matching using an iterative technique, the results of
which are then applied to the whole field using a fuzzy pattern recognition
procedure. Using Neural Networks for Candidate Selection and Well
Performance Prediction in Water-Shutoff Treatments Using Polymer Gels—A Field
Case Study describes how to build, train, verify, and apply neural network
models to evaluate candidate wells for gel-polymer water shut-off treatments in
the Arbuckle formation.
In Prediction of Temperature Changes Caused by Water or Gas Entry into a
Horizontal Well, a model is developed that integrates reservoir and
wellbore flow to asses temperature changes induced by gas influx from the
reservoir and water cut from both the reservoir and from a lower water zone
that is coning.
The following three papers are about scale and treatment approaches.
Placement Using Viscosified Non-Newtonian Scale Inhibitor Slugs: The Effect
of Shear Thinning examines how heterogeneous layered reservoirs respond to
injection of scale-inhibition and shear-thinning fluids in both linear and
radial flow systems. The Kinetics of Sulphate Deposition in Seeded and
Unseeded Tests develops a rate law for barite deposition in brines,
determines the rate constant from experimental tests, evaluates the effects
seeding, and suggests that “safe envelopes” can be defined for each system.
Scale Inhibitor Squeeze Treatments Deployed From an FPSO in Deepwater,
Subsea Fields in the Campos Basin describes procedures, treatments,
surveillance techniques, and overall management of scaling in deepwater, subsea
fields offshore Brazil.
Last but not least, Hydrate Remediation in Deepwater Gulf of Mexico
Dry-Tree Wells: Lessons Learned discusses the source of hydrate plugging on
reopening of shut-in offshore wells, the use of hot oiling to melt the plug,
and suggested start-up procedures to minimize the problem. These are nine very
interesting papers to ponder. Thank you.
