Saphir NL; Pressure Transient Analysis Pressure Transient Analysis, or PTA, is, in most cases, about analyzing high frequency, high resolution shut-in data. The data are captured during dedicated well test operations such as DSTs or production tests or during routine operational shut-ins by Permanent Downhole Gauges (PDG). The pressure response from these shut-ins can be used to provide information about the reservoir within the radius of investigation for radial flow or the area of investigation for more complex geometries.

INTRODUCTION TO WELL TESTING • Introduction To Well Testing 1 • Types Of Well Testing 2 • Well Test Interpretation Methodologies 3 • Introduction To Ecrin Software & Conclusion 4 1 9/12/2014. Introduction To Well Testing 2 3 “Well testing is the technique and method. IHS WellTest software helps you conduct pressure transient analysis and serves as an everyday well test data interpretation and forecasting tool. Operations (well tests), that would determine important reservoir characteristics such as well productivity. Transient Analysis software. Today, safety and economics combined with. Saphir, the Pressure Transient (PTA) module of the Ecrin workstation, is the industry standard with over 3000 active installations. Petroleum E&P software, training & consulting, Pressure and Rate Transient Analysis, Production Log and Formation Test Analysis, Field Performance Analysis. This course will help reservoir and production engineers, geologists and well technologists build reservoir or sector models with no previous experience.

The diagnostic plot of choice is the loglog plot where the pressure and the Bourdet derivative allow the identification of reservoir geometry and properties, these are then matched with models. Specific operations require specific processing, such as multirate gas tests, interference tests, multilayer tests, etc. The development of deconvolution in Saphir NL allows us to combine several of these shut-ins in time to provide information much deeper into the reservoir than would normally be feasible by a shut-in alone.

Saphir NL is the industry standard PTA software, used by nearly all major IOC’s, NOC’s, Independents and Service Companies. Daewoo G35s-2 Repair Manual more. Its simple user interface and workflow allows for fast training and self-learning for occasional users.

For the advanced user, it offers a unique combination of analysis tools, analytical models and numerical models which can connect to other dynamic data application such as Topaze NL for Rate Transient Analysis and Rubis for fullfield history matching.
