This case study explores how BQCIS deployed Digital Assurance tools to optimize
refinery throughput monitoring. By combining custody-transfer data with
advanced analytics dashboards inside the
Digital Assurance Hub,
operators achieved real-time visibility into losses, product yields, and compliance KPIs.

Challenge

A Southeast Asian refinery processing 220,000 barrels/day faced recurring
reconciliation gaps between measured throughput and final yield outputs.
This created disputes during settlement with suppliers, regulators, and joint-venture partners.

BQCIS Approach

• Deployed inspectors to witness crude unloading, tank gauging, and metering calibration.
• Linked custody-transfer results to the
  Refinery Analytics Dashboard.
• Created daily reconciliation reports comparing gross throughput vs. adjusted yields.
• Applied ASTM and
  ISO standard calculations for density, sulfur, and BS&W.

Results

• Throughput–yield variance reduced from 3.5% to 0.7% within 6 months.
• Settlement delays cut by 50%.
• Automated dashboards enabled real-time KPI tracking across 12 refinery units.
• Improved regulator trust with tamper-proof reporting.

Benefits

Key advantages realized from implementing BQCIS Digital Assurance:

• Transparency — Joint-venture partners shared real-time access via dashboards.
• Efficiency — Reduced reliance on manual reconciliations.
• Financial Control — Cut losses linked to unverified variances.
• Regulatory Recognition — Aligned with ISO 9001 reporting structures.

• ISO Standards — Refinery operations, quality & safety
• ASTM Methods — Density, sulfur, reconciliation protocols
• BQCIS Refinery Analytics Dashboard

• QR-Secure Certificates
• Client Portal — Shared access to reports
• Aligned with ISO 45001 refinery safety protocols
