Topaze
Topaze was developed in response to production analysis (PA) evolving from empirical methods to a methodology more closely aligned to modern transient analysis. The old methods have been largely replaced by advanced methodology such as the Blasingame plot and using true diagnostics developed in pressure transient analysis (PTA). Topaze is use with clients ranging from the Major IOC's to NOC's, smaller independents and consulting companies the world over.
The merging of the modeling capability of Topaze with the abundance of data from permanent gauges has meant that users are able to obtain answers that were previously only available from transient tests. This information has the advantage that it is available at no extra cost and with no deferred production. As the long-term production is modeled, the evolution in time of the well productivity may also be quantified. Model capabilities are the same as those used in Saphir. Finally, forecasting is based on real models as opposed to an empirical function.
