Executive Summary

Dean Wehunt, Chevron

Why do you read and also support SPE Prod & Oper? Hopefully one reason is that you recognize the value of peer-reviewed technical literature in your chosen field. Anthony Kovscek shares some excellent insights on this topic in his June 2012 SPE J. Executive Summary. Peer review is valuable, but not infallible; SPE members are encouraged to submit discussions for peer-reviewed papers. These discussions, and the authors' subsequent responses, are an important final step in ensuring the technical quality of our society's peer-approved literature. For submission instructions, see the bottom of the Journals page on SPE.org.

If you were expecting one-stop shopping in this issue for all the peer-reviewed production- or operations-relevant content, you may be disappointed. Some of those papers often land in the society's other journals. To catch those, scan the titles for all seven SPE peer-reviewed journals. At the bottom of this Executive Summary, there is also a list of recent titles that might interest SPE Prod & Oper readers.

This issue contains four fracturing papers, one acid-treatment interpretation and injection-profiling paper, and four chemical technology applications papers. In Measurements of Hydraulic-Fracture-Induced Seismicity in Gas Shales--a paper that may impact the future regulatory framework for fracturing--the authors show that all of the monitored fracture treatments in their extensive database released seismic energy thousands of times too weak to be damaging or harmful. The authors of the next fracturing paper, A Comparison of Hydraulic Fracture Modeling With Downhole and Surface Microseismic Data in a Stacked Fluvial Pay System, illustrate the advantages of calibrating fracture-geometry interpretations using more than one approach, and find that downhole microseismic monitoring is more consistent than surface microseismic monitoring for matching the results from hydraulic-fracturing models. The authors ofMultiphase Fluid-Loss Properties and Return Permeability of Energized Fluids study leakoff of multiphase fracturing fluids under dynamic conditions and show that gas leakoff plays an important role in promoting cleanup of the fracture face area by maintaining a higher gas saturation in the near-fracture area.A New Way of Staged Fracturing Using Ball Sealers is a case study of using ball sealers to divert fracture treatments for a workover program in previously developed horizontal wells.

In our lone paper about acidizing and also flow-profile measurement in this issue, Diagnosis of Acid Placement From Temperature Profiles, the authors have coupled wellbore and formation thermal models, and have developed an inverse model for interpreting the distribution of acid during treatment of a horizontal well based on distributed temperature measurements recorded during and after the treatment.

We conclude with four chemical technology applications papers, including three about scale management. The authors of Surface and Subsurface Requirements for Successful Implementation of Offshore Chemical Enhanced Oil Recovery describe how advancing technology is making it more desirable to perform more EOR offshore, and they also discuss the obstacles that will need to be overcome to make that happen. In The Effects of Barium Sulphate Saturation Ratio, Calcium, and Magnesium on the Inhibition Efficiency: Part I--Phosphonate Scale Inhibitors, the authors show the relative importance of strontium, calcium, and magnesium ion concentrations on the effectiveness of four commercially available phosphonate-based scale inhibitors across a range of North Sea and formation-water compositions. Watch in a future issue for the followup paper, with results for three polymeric scale inhibitors. The authors ofEnhancing Production by Removing Zinc Sulfide Scale From an Offshore Well: A Case Historyshow that elevated pressure can reduce the effectiveness of some treatment formulations, and laboratory analysis of treatment alternatives at more realistic conditions can improve results in the field. In a followup paper, also available through the Online First feature, the authors of Application of Multi-Rate Well Tests to Scale Management: Part 2--Interpretation of MRTs With Known Produced Water Origin use field data to illuminate the use of their method.
