Rubis Modeling and Problem Solving

  • Highly practical with hands-on model building from day 1
  • No previous or specialist simulation experience required
  • Immediate return on investment with attendees able to build history matched models, run what-if? scenarios, and forecast upon completion of the course

Rubis sits between 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 KAPPA-Workstation. This is used to build a predictive model ‘bottom up’.

This course will help reservoir and 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.

Pre-requisites to attend the course

No prior simulation knowledge is required. Previous experience in using KAPPA-Workstation 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 and production analysis are NOT 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.

Course programme

Basic theory

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

Rubis mechanics and model building

Introduction to Rubis and its role in KAPPA-Workstation 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 PVT states. Importing and loading data from various sources including Geomodelers.

Running the model

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

Specific problem solving

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.

Practical integration with PTA and PA

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.

Full Field Case History

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