Sulphur Methodology


Updated March 2018

2017 Estimates

All values for 2017 have been estimated using data reported by industry up until the end of August 2017. Full-year estimates for 2017 were derived using these data, adjusting for seasonality.

Forecasting Methodology

The AER uses sulphur production volumes submitted by operators to Petrinex in the forecast. Petrinex is a secure, centralized information network used to exchange petroleum-related information.

There are three main sources of sulphur production in Alberta: sour natural gas processing, crude bitumen upgrading, and crude oil refining. Sulphur production volumes are a function of sour gas production, sulphur content, and gas plant recovery efficiencies.

The values in this report are now consistent with those published in the ST3: Alberta Energy Resource Industries Monthly Statistics sulphur report. Because sulphur is fairly easy to store, imbalances between production and disposition have traditionally been accommodated through net additions to or removals from sulphur stockpiles. If demand exceeds supply, sulphur is withdrawn from stockpiles; if supply exceeds demand, sulphur is added to stockpiles.
