A decade ago, Repsol executives realized that increasing pressure from local regulators and rigorous European emissions legislation as well as from ESG investors meant that their company needed to establish more reliable and credible environmental management processes. Repsol’s legacy processes for calculating air emissions were disparate, labor intensive and time consuming. Each facility had its own process to create the required regulatory reports and documentation. Many consisted of a series of steps to copy information from source systems – such as PI, laboratory information management systems (LIMS) and production systems – then create and maintain hundreds of spreadsheets with all the necessary calculations and reports. Each process required a host of manual tasks, which had to be performed repeatedly by Health, Safety and Environmental (HSE) staff. As a result, these facility-specific processes left room for human error and provided only limited visibility across the company.

Repsol is one of the world’s leading integrated energy companies, with a broad footprint that extends across more than 40 countries on five continents. Repsol is the major Oil and Gas Company in Spain, based on its extensive upstream and downstream operations, including exploration and production, refining, distribution and marketing, petrochemicals and power generation. Among its key core values, Repsol is committed to maintaining compliance with legal and regulatory requirements and aiming for a neutral environmental impact.

Repsol launched a major project called EMISphere that would centralize compliance by implementing an enterprise-level Environmental Information Management System (EMIS). After weighing several options, the company chose the Sphera® Essential™ solution. Repsol launched the EMISphere project in 2012 with implementations at two facilities in Spain. The system was designed to streamline processes for monitoring and measuring compliance with air, water and hazardous waste permit limits at the company’s refineries while delivering full visibility into its HSE performance. Repsol’s team used the Sphera Process Data Manager module to seamlessly move data from their PI, LIMS and production systems directly into the EMIS. Furthermore, the system enabled a superior level of automation in terms of scheduling, validating and applying rules and calculations to process data in an auditable, transparent way.

• Air and water emission reports at each facility are now produced in 3 weeks instead of 3 months on an annual basis thanks to data automation.
• 99% automation for compliance-related tasks – reports are now just one click away.
• Complex business rules for each facility’s regulatory requirements have been incorporated into the system, so most manual tasks have been eliminated, resulting in improved data integrity, quality and accuracy.

• Reduced time required for air and water emissions reporting on an annual basis from 3 months to 3 weeks
• Enabled 99% automation for compliance related tasks
• System performs more than 1 million calculations daily with 4000 signals integrated; and stored 5 million emissions calculations annually
