Bonjour, SPEPO readers, and welcome to the third-quarter edition. Once again, the hard-working authors and volunteer editors have provided you a fresh serving of peer-approved petroleum literature. Remember, if you want to learn how to get involved in the Editorial Committee or to serve your profession in some other way, please see http://www.spe.org/volunteer/, and if you want to be an author, go tohttp://www.spe.org/authors/.
SPE Technical Director for Production & Operations Shauna Noonan provided the following exciting announcement about a special session at the 2013 ATCE:
For the first time, the SPE Technical Directors have combined forces to create a multidisciplinary special session at ATCE 2013 that will be held on Tuesday morning, 1 October. The topic is "So We Frac'd the Well, Now What?" and will bring together industry experts from the relevant disciplines to discuss the issues related to long-term viability of oil and gas production from shale. The 2012 SPE International Production and Operations Award recipient, John Patterson, will be the panelist representing SPE's Production & Operations technical discipline. Other panelists will include recognized industry experts such as George King and Tom Blasingame. The moderator for the session will be former SPE P&O Technical Director James Pappas. Don’t miss out on this great session, and join us at ATCE 2013.
If you haven’t already made plans to attend the ATCE, learn a lot, and laissez le bon temps rouler à la Nouvelle-orléans: you haven’t missed the flatboat swamp tour yet. See the conference web site athttp://www.spe.org/atce/2013 for details.
And now, we move on to the papers. This edition of SPEPO features four hydraulic-fracturing papers, three acidizing papers, and two multiphase-flow papers.
In Engineering Approach To Optimize Development Strategy in the Oil Segment of the Eagle Ford Shale: A Case Study, the authors describe their field application of X-ray fluorescence to identify preferred completion intervals, and they also provide additional data regarding the comparison between the ball-drop or plug-and-perf completion methods. The authors of Simulation of Gel Filter-Cake Formation, Gel Cleanup, and Post-Fracture Well Performance in Hydraulically Fractured Gas Wells developed a mechanistic model that uses laboratory data to predict the accumulation of filter cake during a fracture job; a key feature is that the model accounts for the transport of sheared polymer molecules into the formation. In another paper about modeling the performance of tight gas wells,Simulation of Fracturing-Induced Formation Damage and Gas Production From Fractured Wells in Tight Gas Reservoirs, the authors used a sector model with an explicit fracture to evaluate the evolution of skin, and coupled the model to a full-field model so that realistic skin factors are used to evaluate the overall field performance over the full field life. The authors of A New 3D Compositional Model for Hydraulic Fracturing With Energized Fluids have developed a new model that is capable of addressing the significant thermal and compositional effects that occur when using compressible fracturing fluids, which should enable better history matching of past treatments and also better assessments of different proposed designs.
In the first acidizing paper, Application of Chicory as Corrosion Inhibitor for Acidic Environments, the authors describe a new application of a naturally occurring material as a corrosion inhibitor. If you need proof that it is safe, just check the ingredients of some of the coffee you will probably drink in New Orleans. Use of the relatively new stimulation product glutamic acid diacetic acid in a 300ºF well with some high-chrome completion hardware is described in Field Treatment To Stimulate a Deep, Sour, Tight-Gas Well Using a New, Low-Corrosion and Environmentally Friendly Fluid. The authors ofExperimental and Field Data Analyses of Ball-Sealer Diversion used a fresh approach in looking at an old mechanical diversion method using new laboratory and field data, and they concluded that seating efficiency is a statistical phenomenon.
This edition also has two papers about high-viscosity multiphase flow. The authors of Investigation and Prediction of High-Viscosity Liquid Effect on Two-Phase Slug Length in Horizontal Pipelinesfound that viscosity is an important influence on the behavior of slugs in two-phase horizontal flow, and they developed a new model to account for higher viscosity liquids in slug flow. In our final paper of this issue,Experimental Study of High-Viscosity Oil/Water/Gas Three-Phase Flow in Horizontal and Upward Vertical Pipes, the authors measure multiphase flows in horizontal pipes and vertical pipes with flow in the upward direction, and they compare their results with existing models to identify discrepancies in those models.

I really like the word "Microtomographic" in that last paper title. It could be worth a lot of points in some word game.
Until next time: être en sécurité!
