Rubis was born as a natural progression from the Voronoi numerical model in the Pressure Transient Analysis (Saphir) and Production Analysis (Topaze) modules of the Ecrin suite. Rubis sits between a single tank material balance and a multi-million cell simulator, not replacing them but doing much of the work they can do, easier, faster and in concert with the Ecrin suite. The basic premise of this module is that all extraneous data be stripped away and that, given we have pressure and rate data that is real, measured and correlating with other dynamic data methods is therefore telling the truth. This can be used to build a predictive model ‘bottom up’.

This course will help not only reservoir engineers but also production engineers, geologists and well technologists build reservoir or sector models with no previous experience. They can then forecast, perform what-ifs and foresee future intervention opportunities and risks with build and run times in minutes instead of days.

No prior or specialist simulation knowledge is required. As the Rubis software environment is very similar to other Ecrin modules previous experience in using the Ecrin Suite will be of benefit although not strictly required. When understanding the complementary nature of the simulation model and the PA and PTA analysis prior experience of these methodologies would be an advantage. The theory of numerical simulation, transient analysis and production analysis are not subjects covered in this course. If you wish to discuss this please contact and one of our trainers will talk it through with you offering pre-course reading/worked examples to give you a head start if needed.

This is NOT a simulation course. The mathematics and theory of numerical simulation are not covered. The entire emphasis is on the building of the physical problem and application of the model to various scenarios.

Introduction to Rubis and its role in the Ecrin suite compared to transient and production analysis leading to flexible upscaling from the wellbore to the full field. Building a simple model: reservoir structure, rock and fluid properties and well description. Defining multiple regions with different initial states. Importing and loading data from various sources including a Geomodeler such as Petrel™.

Automatic grid building, run settings, initialization, simulation, displays, re-runs, what-ifs and reporting.

Recovery comparisons for different field scenarios and well placements. Adapting the grid to model coning effects. Modeling and adjusting the aquifer model and strength. Modeling multiple and connected gas tanks.

Initializing a Rubis case from Production Analysis (Topaze) and returning this to the production analysis. Initializing a Rubis case from Pressure Transient Analysis (Saphir). Using a sector of a Rubis case to analyze a build-up in Saphir.

The course culminates in the attendees building a full-field history matched model leading to production optimization and a forecast of primary recovery and then offering scenarios for secondary recovery.
