Let us help to minimize the impact of your product losses.

Wetstock management is offered to oil companies that want to avoid product losses in their fuel stations network. On a daily basis our wetstock analysts compare pump meter readings vs. tank gauge readings, with the objective to detect extreme variances as soon as possible. The earlier theft, leaks or meter drifting is detected, the faster corrective actions can be taken and the smaller the financial impact is of these incidents.

Our service activities

Data verification & cleaning

We run daily checks on inventory, sales and delivery data, using tank specific thresholds, to validate and clean this data and ensure accurate reporting.

Real-time leak alarms

We monitor alarms that come from the ATG or are generated by our software, to identify leaks as soon as they occur to minimize the impact for customers.

Real-time alarms

We monitor alarms that come from the ATG or are generated by our software, to identify incidents such as water in tanks, tank overfills and probe faults.

Extreme variance analysis

We identify extreme variances based on tank specific thresholds, analyse the root cause of this variance and define the appropriate route for resolution.

Meter drift analysis

We identify meter drift over time via transaction based analysis to highlight pumps that are potentially over dispensing.

Drainback test

We monitor dispensers and lines to identify incidents of drain back and to avoid a negative customer experience and increased stress on equipment.

SIR analysis

We run our USEPA certified Statistical Inventory Reconciliation (SIR) process weekly, based on in house algorithms and wider data range, to identify leaks.

Loss investigation management

We run our Loss Investigation process that guides our customers and advises on the steps required to minimise the impact of the fuel loss incident.

Inform customers

We work closely with our customers and inform them as soon as possible to minimize the financial impact of fuel loss incidents.


Three reasons for wetstock management

  1. Minimize the cost of fuel loss. From loading at the terminal to selling at the pump, there are many points where fuel can be lost or even stolen, but most companies can’t see where these are happening.

  2. Reduce the investigation time. When an unusual loss is seen in legacy systems, the lack of understanding of the exact reasons behind the loss can lead to a costly manual, inefficient and error-prone investigation process.

  3. Avoid fines and clean-up fees. The financial risks of fuel loss, including fines and the need to clean up leaks after the fact, are not inconsiderable. Also there is the impact of reputational damage that can hurt your business.

“AVIA Weghorst is a data driven company and I believe that the wetstock management services of Bottomline can help us to reduce fuel loss in our network.
