7. Mechanical Testing Program – Phase 1
Participating Laboratories
Baker Hughes, Chevron, CSI, Halliburton, OFITE, Schlumberger, Trican, CURISTEC
Base Slurry Design
Class G and fresh water
Medium weight slurry (Class G & Poz blend) & Lightweight designs was discussed, decision was to defer until conclusion of Class G & Water testing.

8. Mechanical Testing Program – Phase 1
Curing Temperature = 50 deg. C
Curing Pressure = 3000 psi
Curing Time = 14 days
Temperature and pressure be reduced over a 72 hour period to minimize induced stress on the samples.
Confining Pressures
All Labs are to test using the following confining pressures
250 psi, 500 psi, and 1000 psi.
Test Specimens should adhere to a 2:1 ratio (length to diameter)

9. Mechanical Testing Program – Phase 1
Labs are to follow their established testing procedures
All labs have the freedom to add additional confining pressures beyond the three required pressures stated above. Tests results can be submitted as well.
All tests will be tested under a “drained condition”.
Labs have freedom to test under an “un-drained condition” as well and test results can be submitted
Phase 1 Testing Deadline: April 01, 2017

10. Workgroup 2016 Highlights Workgroup members increase = 63%
Action Items completed = 96%
2016 Workgroup meetings = 5
Positive participation in all meetings

14. Thank you and Questions

15. Minutes: 10:45 Session called to order
A. Badalamenti presented recap for:
2016 activities, 2017 phase 1 testing plan and action plan
Discussion items
Phase 1 testing regime, report standardization and data analysis
Matthew Goodine asked about allowing each lab to use their processes for testing regime – A.B explained that a standardized process will be used to prepare the cement slurry, cure, depressurize/cool the sample, etc. Load frame loading and testing will be as per each labs’ processes and procedures

16. Minutes: Discussion items
James Heathman asked how would the test data would be collected and analyzed – Axel Bois explained that the “raw test” data would be used
Rick Lukay – suggested that a standardized test report be created to ensure that all needed data is collected and received – Anthony and Axel will generate the test report and distribute it to the lab.
James Heathman suggested that each lab use the same cement design
Maggie Benge - explained that a standard slurry design is being developed and sent to each participating lab.
Rick Lukay – motion for session closure – motion was seconded, no objections. – meeting adjoined 11:10 am.
