• Lab testing 实验室试验 – Simulate job conditions as accurately as possible – Do not assume standard API conditions – Strict quality control of all blends (SSA-1 content) – Cementing rep. offshore/onshore in charge of bulk management – Quality control all materials and perform confirmation testing using field samples – Material traceability back to producer – Aim for a single chemical batch number, especially for retarders. – Communication is important to remain proactive – Allowance in design for change in plans
