Case Study: Petroleum and Natural Gas Company uncovers millions in lost revenue with CaseWare Analytics' CaseWare Monitor

Petroleum and Natural Gas Company - Customer Case Study

Petroleum and Natural Gas Company, a US$10+ billion exploration and production firm, struggled with weak internal controls, manual accounts payable processes and untrained staff, leaving transactions and policy breaches untracked. After expensive but ineffective third‑party analytics, the company engaged CaseWare Analytics and its CaseWare Monitor continuous controls monitoring platform to provide real‑time monitoring and controls oversight.

CaseWare Analytics’ CaseWare Monitor and Professional Services team ran a two‑year risk and controls assessment and applied advanced analytics to identify risks across accounts payable, audit automation, purchase card and vendor management. The solution uncovered major issues — including more than $614 million in missed discounts, over $144 million in duplicate invoices, $66.5 million paid on inactive wells, nearly 10,000 purchase‑card transactions (~$1.6M) flagged as potential personal use, and thousands of duplicate vendors — enabling the company to recover funds, strengthen controls and expand CaseWare Monitor to other processes.
