The Production Allocation Standard app allows oil and gas organisations to monitor their business processes for production, transport and sales of oil and gas, in order to understand the value realised and to properly manage the associated resources.

It is essential to have a system that manages this critical production data, accurately calculating and allocating the values in order to comply with commercial and regulatory requirements. The app has all the functionality you would expect from a COTS solution, plus all the unique configurability of the EnergySys platform. It is a complete end-to-end solution for hydrocarbon allocation and reporting, from production to transport and sales, with the flexibility to configure the system to meet your specific needs, faster and more easily than any other solution on the market today. Up to 75% faster than traditional systems.

We’ve just added a new US version of our Production Allocation Standard app. Designed to cater for the individual needs of the US onshore market, we’ve made it even easier and faster to get up and running with EnergySys.


The standard app includes a comprehensive module for allocation of mass, energy and volume based on measurements, well tests and well decline curves. Allocation networks consist of Facilities, Fields and Wells of any user-defined type.

Facilities are locations in the network where an instrument reading, or derived reading, is available for allocation. They represent production Facilities, such as Platforms and Terminals, or may simply be a group of wells that is independently metered. Facilities may also be related to other Facilities, allowing the possibility of arbitrarily complex allocation hierarchies.

While the standard module is highly flexible and should meet the majority of users’ requirements, the system also allows you to completely re-define the allocation logic to reflect special arrangements you may require. This includes modifying or completely replacing the existing algorithms with, for example, your own spreadsheet model.
Data locking helps you avoid unintentional changes to results after data has been published.

Reconciliation is generally a monthly process that is invoked when new data becomes available. Examples might be receipt of a monthly sales figure that can be used to improve daily data, or improved fluid characterisation arising from an updated sample analysis. Reconciliation offers an option of re-allocation back to the wells for each day in the period to be adjusted.

Adjustments may also be necessary in the event of mismeasurement. When an error is found it must be possible to record the correct figures in the system and, if necessary, re-run the allocation for one day, or a period of days. The Production Allocation Standard app provides formal logs for mismeasurements and stock adjustments, including the reason for the adjustment.

EnergySys allows data to be entered directly into the screens, posted to the system as email attachments, or manually uploaded. Files can be uploaded in Excel, CSV or text format, and you can load them in bulk by providing together a zipped collection of data files. The layout of these upload files is not specified by the system, and the import process can be configured to read almost any layout and import the data to the system. This is extremely important when a third party specifies the layout and it is not under your control. For automated interfaces with a SCADA system or data historian, you can upload your data via a a web services interface. There are validation and verification checks on all raw metered data imported into the system.

The standard app allows you to record operational events and assess their impact on associated business plans. This includes daily operations on wells and facilities, including the classification of events that can lead to deferments. All deferments are related to production at the well, although they may be caused by events at the well, field or facility. The system also allows named plans to be recorded, and compared with actual production performance.

The standard app is provided with a number of beautiful standard reports, as well as ad-hoc reporting domains. These standard reports include interactive drill-down dashboards, daily operations reports, and partner reports. In addition, template reports can be developed to meet client-specific requirements. The ad-hoc reporting system provides you with the means to investigate and report on data on the fly, using sophisticated drag and drop design capabilities within the browser.
