Overview of All Tasks March , Milan, Italy

Task 1 - Monitoring Monitoring Methods Conventional methods completed Need to add fiber optics Need to finalize PLTs Need to improve fractured monitoring Need to incorporate specific Best Practices – suggestions?

Task 1 - Monitoring Fracture ModelsAudit and Summary Completed Add “high-level” comparison to Best Practices Any missing models?

Task 1 - Monitoring Well Performance Prepared introductory level presentation on Well Performance for Injectors Radial flow completed Wellbore Hydraulics Completed – more on restrictions Completions

Task 2 – Matrix Injection Methods for Performance Assessment Methods for Mitigating Plugging Integrated with Tasks 3 and 4 Incorporate in Best Practices Finalize Stimulation Selection Tool Evaluate recent Chevron dataset (also Soft Formations)

Task 2 – Matrix Injection Radial Damage Modeling PWRAD Damage Exponents Characteristic Signatures

Task 3 – Soft Formations Data Evaluation Models Weyburn data remains to be considered? Document prepared and needs to be added to Best Practices site

Task 3 – Soft Formations Theory Data Evaluation Models Overview document is in Toolbox Weyburn data remains to be considered? Document prepared and needs to be added to Best Practices site

Task 3 – Soft Formations Completions Worksheet Completions Skin Version in ToolBox “works” with Toolbox Laurence Murray version works properly version Version that is having Help integrated. Help Document prepared and has been added to Best Practices site

Task 4 – Stimulation and Mitigation Introductory Document on Methods Signatures Stimulation Selection Routine Surface Systems Economics? In Best Practices - needs peer review Draft Version in ToolBox Needs section in Best Practices Upcoming Release ?????

Task 5 – Layered Formations Is still weak. Some mitigation methods from Workshop. Some monitoring methods.

Task 6 – Horizontal Injectors Analysis methods PowerPoint presentation. Needs to be written up for Best Practices Some data analysis Needs to incorporate examples and methods particularly for bringing wells on line.

Task 7 – Database All electronic numerical data has been entered except Weyburn and complete Maersk data set. However, Maersk data set has and continues to be used extensively for Stimulation Task. PC version available. Need to integrate databases.

Task 8 – Field Validation Update summary spreadsheet. Process recent Heidrun data set. Process other new examples.
