Near-Wellbore Simulator
The project is supported by The Research Council of Norway (Petromaks), BP and ConocoPhillips. The project runs from October 2006 through to December 2009. The total budget is 20 million Norwegian crowns.
The main objective of the project is to contribute to a safer and more efficient production of oil and gas from carbonate (chalk) formations with cracking and solids production problems. The project will address cases from Ekofisk and Valhall.
The main result of the project is an application, built on Brilliant, specially designed for simulation of the multi-physics processes involved in oil and gas production from a production well, addressing in particular the near-well region and well in-flow zone. The processes involved are drainage of oil and gas from the reservoir formation, effects on the rock structure from production flow and flow of the fluid from the well to the surface.
The application will consist of three integrated modules:
- Simulation module for multi-physics simulation with different mathematical models included;
- Graphical interface module for definition of simulation case and communication to other systems (database);
- Visualization module for presentation and post-processing of results.
The application will include suitable models for:
- Flow in porous media as well as multi-phase flow in pipe
- Stress analysis applicable for analysis of rock and steel
- Crack analysis and crack influence on flow
- Effect of chemical injection
- Solids production
The different models shall operate and interact simultaneously with each other in different time scales. The application shall operate within one grid covering the reservoir and the multiphase flow in the production line. The application shall be suitable for production planning and optimization.
