National data repositories aim to collect and organize all relevant petroleum resources information within a country. This helps developing nations gain more control over their natural resources and budgets by developing their own oil and gas industries. Web-based systems provide intuitive interfaces to capture industry data using standards-based forms and workflows, making information easily accessible to technical and managerial staff. Organizing a country's petroleum data into a national repository adds value by helping attract further investment and ensuring resources benefit the nation over the long term.
