Industrial cloud improves custody transfer, remote monitoring for oil applications
Trigg Technologies LLC uses a cloud-based platform and remote monitoring to improve custody transfer services accuracy and reliability for crude oil and petroleum products.
Cloud-based computing applications are integrated into a Lease Automatic Custody Transfer (L.A.C.T.) unit from Trigg Technologies LLC to accurately measure, sample, and transfer hydrocarbons between buyers and sellers. The skid-based unit can be placed at any custody transfer location for oil production facilities, trucks, railcars, pipelines, storage tanks, barges, and tankers.
Flowmeters on the skid transfer information to an enclosure, feed data into the cloud, and the custody transfer is verified in real time; manual paper-based systems pose challenges later, which is difficult and time-consuming when discrepancies are found, technology provider Rockwell Automation suggested. Mass flowmeters compensate for errors based on temperature. Crude oil expands or contracts at 2% per 40 F temperature change, something typical tank gauges don't catch; even a 1% error, with $100/bbl oil at 3000 bbl/day means $1,095,000 of lost revenue per year, Trigg Technologies suggested. A larger application with 2% to 8% error rates can suffer unrecovered losses of $11-14 million per year, according to a Rockwell Automation representative.
Local, remote access
Information about the custody transfer and system health can be seen at the enclosure (see photo) human machine interface (HMI) and on enabled and secure laptops, mobile phones, and tablets, as well as by remote monitoring and support personnel tracking real-time system alarms, event faults, and notifications, offering predictive and preventive maintenance to maximize reliability. The cloud platform also provides secure data storage, workflow assistance, and a cross-platform dashboard with reports. "Cloud technology provides a vehicle to manipulate and manage data. Purchasing software as a service enables an organization to move faster into the realm of operational excellence through better utilization of existing data. Purchasing operations management tools as a service avoids using capital budgets and specifically circumvents issues of funding across assets. Services are paid for as they are used with operating budgets. Utilizing cloud computing to share operating conditional data creates an environment for operational improvement. 'Private clouds' leveraging the same technologies can be deployed if an enterprise has considerations that require all of the data to remain within their enterprise (regulatory compliance, investor compliance, etc.)," as explained in a Rockwell Automation white paper, "Helping Oil and Gas Companies Achieve Operational Excellence."
