API SC10 Cooperative Test Program 2018: Pre-check on Consistency/Homogeneity 1a. Selection of a sufficiently large sample 5 big bags sorted out from running production 1b. Check on consistency/homogeneity Representative samples taken from these big bags Conduct complete API Spec 10A tests on these samples Compare results and release four big bags (# A-D) for Cooperative Testing (deviding to small shipping samples)  

API SC10 Cooperative Test Program 2018: Pre-check on Consistency/Homogeneity 2 consistometers, 2 operators

API SC10 Cooperative Test Program 2018: Dyckerhoff Class G Sample Preparation 2. Preparation of test samples – sample slitting disposal of top layer of cement in the big bag (about 20 cm) quick filling of small quantities (4 kgs) of sample cement into double polyethylene (PE) bags bag label between PE bags (bag content label) poperly store remaining, not shipped sample cement

API SC10 Cooperative Test Program 2018: Dyckerhoff Class G Sample Preparation Label on PE bags

API SC10 Cooperative Test Program 2018: Dyckerhoff Class G Sample Preparation numbering / marking PE bags a hard copy of the Material Safety Data Sheet (MSDS) is placed into every bucket numbering & marking of the sample buckets

API SC10 Cooperative Test Program 2018: Dyckerhoff Class G Sample Preparation (Content) Label on bucket

API SC10 Cooperative Test Program 2018: Dyckerhoff Class G Sample Preparation Packaging: 2 PE bags of 4 kg each in one plastic bucket (20 liter = ca. 5 gal) Total sample weight (cement): 8 kgs Content label Address label

Sample Preparation: Monotone Work Which, However, Requires Attention & Care …

API SC10 Cooperative Test Program 2018: Assignment of the Samples Participant No. 2 = Schlumberger Part 1 (of in total 5 collective shipments), = collective shipment of 24 samples Participant No. 1 = Halliburton = collective shipment of 70 samples to Houston RSP = Reference (retain) sample

API SC10 Cooperative Test Program 2018: Sample Distribution 3. Distribution of samples Recipients/addressees according to the participants list provided by API The bags and bucket numbers for each participant were recorded Generally: Single shipments one bucket per participant Collective shipments one shipment with 9 to 70 samples on wooden ISPM 15 pallets, further distribution by the recipient, usually subsidiaries or field labs of the recipient.

API SC10 Cooperative Test Program 2018: Sample Distribution Collective sample package ready for dispatch

API SC10 Cooperative Test Program 2018: Organization of Sample Shipment 4. Organizing sample shipment select and instruct forwarding company decide on method of shipment Single samples: by courier service Multiple package to one destination: by air freight issuing of the complete shipping and customs documents for each shipment (participant) shipping documents must include a pro-forma invoice + packing list for facilitation of customs procedures a low value of the material was declared (24 € per sample) Certificate of origin, issued by the chamber of commerce is to be added for certain countries For certain countries shipping documents were sent to receiver in advance for approval. Once received sample was released.

API SC10 Cooperative Test Program 2018: After Shipment Activities follow up of delivery status via courier service internet tracking modification of shipment documents upon request dispatch of additional documents when requested provide new set of samples - late coming participants (6 times) answer technical inquiries, resolve technical & logistical problems (1 case)

API SC10 Cooperative Test Program 2018: Shipping Statistics # of collective total # shipments of samples Collective shipments Halliburton 1 70 Baker Hughes 2 24 + 15 Schlumberger 5 23 + 17 + 16 + 14 + 9 Lafarge 2 13 + 10 + 1 Single shipments (1 sample) 33 Total number of samples shipped: (= participating laboratories) 245 Total # of participants (companies): 38 Sample not released from customs due to missing confirmation/receipt: 2

API SC10 Cooperative Test Program 2018: Problems & Proposed Measures 8. Problems and Proposed measures Aging of test samples Ship test quantity in several small (in participant's lab) portions, separately packed in double PE bags Damaged buckets using buckets of strong material, add hint on bucket "Fragile" Sample undeliverable Phone no. and e-mail of contact person is of vital importance (must be part of the application form and shipping documents) Subsequent shipments Keep a sufficient quantity of sample cement on stock (suggestion: 10 % of the total, shipped quantity) Customs problems Check and obey applicable specific regulations for every country. Import to some may require addition of a Certificate of Origin to the shipping docs, some also a Certificate of Analysis (API Spec 10A test report)
