Executive Summary

Dean Wehunt, Chevron

Howdy e-readers! Welcome to the first ever “online only” edition of SPE Production & Operations (SPE PO). Previous online subscribers may not have noticed that the print version of SPE PO is no longer offered, or that this change is also being made for a few other journals at the same time. I meekly protested the change (with all my might), but the SPE publications staff told me that they ran out of trees. So, if you have an iPad, search the Apple App Store for “SPE Peer-Reviewed Journals” to find the reader app. The app will also soon be available in Android and Kindle Fire formats. And if you are still not too sure about this technical leap forward, all current subscribers to any of SPE’s journals now have access to all previous issues of that same journal as part of their annual subscriptions, which sounds like a really good deal.

Now, let’s move on to the seven peer-approved papers in this edition, followed by a list of recent peer-approved papers you may be interested in from other journals.

Scale Inhibition

The authors of Use of Tracers To Evaluate and Optimize Scale-Squeeze-Treatment Design in the Norne Field demonstrate how to use a reservoir model, a test slug of KCl water, and field flow measurements to characterize the reservoir layers and optimize a scale-treatment design. In Minimizing Environmental and Economic Risks With a Proppant-Sized Solid-Scale-Inhibitor Additive in the Bakken Formation, the authors report encouraging results from more than 140 wells treated with a new environmentally-friendly proppant-sized solid scale inhibitor, and compare their results with a control group of untreated wells. Multiple history-matched reservoir models are used by the authors of Estimating Scale Deposition Through Reservoir History Matching in the Janice Field to predict the uncertainty in sulfate scale deposition.

Well Stimulation

The authors of Effect of Oil Saturation on the Flow of Emulsified Acids in Carbonate Rocks evaluated the effects of oil saturation in carbonate cores on both the volume of acid to achieve breakthrough and the size, number, and distribution of the resulting wormholes. In Activator Development for Controlling Degradation Rates of Polymeric Diverting Agents, the authors discuss the development of chemical activators that will degrade polymers used for diversion with a reduction or elimination of the detrimental effects that can be caused by strong acids or bases.

Natural-Gas Storage

Analysis methods, including strongly-coupled fluid mechanics and heat-transfer modeling, and practical application examples are provided in Effective Modeling and Analysis of Salt-Cavern Natural-Gas Storage.


The authors of CFD Modeling and Experimental Observations of Changing Surface Profiles Caused by Solid-Particle Erosion consider the impact of the changing surface profile on erosion rate for three commonly encountered scenarios, including a cylindrical rod, a hole in a flat plate, and a pipe cavity.
