Executive Summary

Dean Wehunt, Chevron

Greetings, SPEPO readers, and welcome to this fourth-quarter 2013 edition. Once again, we bring you a little news, but more importantly, the authors and technical editors bring you a great deal of solid new technology with this round of peer-reviewed papers.

Shauna Noonan, the SPE Technical Director for Production & Operations, provided the following comment about writing papers for SPE events:

The main source for SPE papers in the OnePetro online library and for peer-reviewed articles is the SPE conferences. SPE workshops—which do not supply papers into OnePetro for permanent accessibility by all members—outnumber SPE conferences almost 3 to 1. With the large influx of new engineers entering the industry, SPE papers are a valuable learning tool for them. The presentations given at workshops could potentially be great technical papers. When you or one of your employees has an interesting workshop topic, please strongly consider the abstract and conference paper option so the information can be accessed in the future by all our members via OnePetro.

Did you know that the full content of the Petroleum Engineering Handbook is now available for free at www.petrowiki.org? In addition to being a good tool for all our members, the information may also be helpful to petroleum engineering educators and students.

Here’s your three-month warning—February is a big month for SPE technical meetings in the P&O discipline. The Hydraulic Fracturing Technology Conference in The Woodlands, Texas, 4–6 February is certain to once again deliver a strong technical program. And if you missed your chance to practice your French and eat some “mud-bugs” at the recent ATCE, you can attend the 2014 International Symposium and Exhibition on Formation Damage Control, 26–28 February, in Lafayette, Louisiana. You can search for upcoming SPE events of all types on the Society’s events page at http://www.spe.org/events.

And now, we move on to the nine peer-approved papers in this edition.


For those within and without our industry who prefer facts to rhetoric, George King, with Daniel King, has provided the industry another valuable, extensive, and possibly comprehensive resource in “Environmental Risk Arising From Well-Construction Failure—Differences Between Barrier and Well Failure, and Estimates of Failure Frequency Across Common Well Types, Locations, and Well Age.”


In “Closed-Loop Feedback Control for Production Optimization of Intelligent Wells Under Uncertainty,” the authors demonstrate that a direct coupling between reservoir monitoring and downhole valve control can deliver higher net present value, and also effectively mitigate many reservoir uncertainties.

Production Chemistry

Past sampling protocols and testing methods may have resulted in underestimating the effectiveness of polymer treatments, according to the authors of “Effective Propagation of HPAM Solutions Through the Tambaredjo Reservoir During a Polymer Flood.” The authors’ new anaerobic sampling and analysis methods reveal gel stability that better correlates with positive results from actual polymer floods.

The authors of “Produced-Water-Chemistry History Matching Using a 1D Reactive Injector/Producer Reservoir Model” use a relatively simple model to demonstrate the value of matching changes in water composition as part of the process of history matching a reservoir simulator.

In “Scale-Inhibitor Consumption in Long-Term Static Barium Sulfate Inhibition Efficiency Tests,” the authors use long-term laboratory tests to show which types of scale inhibitors will provide the longest protection, and they also identify when there may be synergies from blending more than one type of scale inhibitor.

The authors of “Experimental Investigation and Correlation of Treatment in Weak and High-Permeability Formations by Use of Gel Particles” studied the injection of gel particle suspensions into sandpacks and identified some conditions in which the particles will deform or break, leading to temporary periods of injectivity improvement, followed by injectivity degradation as the plugging process continues.


The authors of “Comparison of Carbonate HCl Acidizing Experiments With 3D Simulations” have used a two-parameter structure-property relation and scaling criteria to model some complex limestone dissolution geometries, with model results that appear to be an excellent match to measured results reported by previous investigators.

Geochemical scaling—diagenesis—can significantly degrade proppant conductivity at realistic reservoir temperatures and within time periods as short as one year according to the authors of “Long-Term Hydrothermal Proppant Performance,” and the application of hydrophobic surface-modifying materials can reduce the impact of this phenomenon; however, laboratory testing is needed to select the right material for a specific application.

Many previous authors have told us that closely spaced hydraulic fractures interfere with each other, and the authors of the very interesting “Investigation of the Impact of Fracture Spacing and Fluid Properties for Interfering Simultaneously or Sequentially Generated Hydraulic Fractures” have begun to tackle the difficult problem of what we can do about this problem beyond the trivial and often undesirable solution of making the fractures farther apart.
