Background
Valero is headquartered in San Antonio, Texas and is the largest producer of refined products in the United States. The company operates seventeen refining plants internationally with a combined capacity of 3.3 million barrels per day.
The Port Arthur refinery became a Datacor customer in 2001. The implementation addressed two distinct operational problems: a chronic data integrity issue that was consuming weekend chemist time every week, and a product shipment bottleneck that was costing the facility hundreds of thousands of dollars in demurrage fees.
The Problem: Data Integrity
Before BLISS, the Port Arthur lab operated on a proprietary UNIX-based system running off a VAX server. The system had a fundamental flaw in how sample data was handled: if a technician entered an eight-digit sample number incorrectly alongside test results, the data became permanently irretrievable. There was no error correction, no recovery path, and no way to associate the results with the correct sample after the fact.
This happened an average of five times per day. The lab referred to it internally as "crazy data."
The operational response was to schedule plant chemists to come in every Saturday and Sunday to manually review the previous week's lab data, identify the errors, and attempt to reconcile what could be salvaged. It was a recurring cost in time and personnel that existed entirely to manage a system deficiency.
After BLISS implementation, data errors dropped from five per day to five per year. The weekend grading sessions were eliminated.
The Problem: Shipment Delays
The second problem was more expensive. To ship finished product, the Port Arthur facility schedules transport time on barges and ocean-going vessels. That time is paid for whether the vessel is in use or sitting at the dock waiting on product release. Large ocean-going vessels can run thousands of dollars per hour at dock. If a delay causes a vessel to miss its next scheduled pickup, the facility pays demurrage fines on top of the extended usage fees.
Product release depends on laboratory results. If a sample is delayed, misrouted, or lost in transit between the satellite lab and the main lab, the entire shipment timeline is at risk and the clock is running.
What Changed
Datacor's Professional Services team developed a custom tracking script that monitors samples from the satellite lab to the main lab. If a sample has not been received at the main lab within a defined timeframe, an automated alert is sent to the on-call chemist by email and text. If the tank final is not completed within a subsequent timeframe, a second alert goes out. The chemist knows immediately when something is off, before a vessel is sitting at the dock waiting.
That script alone has saved the Port Arthur facility hundreds of thousands of dollars.
"The Professional Services group is second to none. You can't throw anything at that group and not get it resolved quickly." — Craig Hoaglin, Senior Chemist
Data Access Beyond the Lab
The Port Arthur facility also deployed BLISS to extend lab data access beyond the laboratory without requiring client software installation or maintenance on remote workstations. Lab personnel use the interface throughout the day. Decision makers outside the lab rely on remote access as a core part of their daily workflow.
Datacor's Professional Services team completed custom development on the interface to address facility-specific requirements, extending its operational value beyond the standard deployment.
Professional Services as a Strategic Resource
The Valero Port Arthur implementation illustrates a capability that distinguishes Datacor from off-the-shelf LIMS providers: the ability to develop custom solutions for operational problems that fall outside standard software functionality.
The sample tracking script was not a standard BLISS feature. It was a purpose-built solution developed in response to a specific, costly problem at a specific facility. That kind of engagement, where Datacor's Professional Services team functions as an extension of the customer's operational team, is a consistent element of how BLISS implementations deliver value beyond the core platform.
An Industry Leader Built for What Comes Next
BLISS LIMS has supported petroleum refining operations since 1985. The platform has adapted through successive technology generations, tracking alongside how refineries operate and how their data requirements have evolved. Each generation brought new demands. BLISS met them.
The next evolution is already underway. AI-driven process optimization and predictive analytics depend on structured, longitudinal operational data. A refinery running BLISS has the data foundation that makes those capabilities actionable. That foundation is not incidental. It is the product of years of disciplined data management, and it is where the next generation of refinery intelligence gets built.
Deployment and Licensing Options
BLISS LIMS is available to refineries at any stage of their modernization path. On-premises deployment is available for organizations managing their own infrastructure, with licensing scaled to the size of the operation. Cloud-hosted deployment is available for organizations prioritizing reduced IT overhead and faster time to value.
Both options are supported by Datacor's implementation team and deliver the same core platform. The path to deployment depends on how your operation is structured, not on what the software can do.
Valero's experience at Port Arthur illustrates what targeted LIMS implementation looks like in practice: measurable error reduction, a custom solution that eliminated a recurring financial exposure, and a Professional Services relationship that continues to deliver operational value.
