Studying the Artificial Ground Freezing Method with Simulation

May 18, 2017

Artificial ground freezing (AGF) is a valuable process in the construction industry. Researchers from China modeled groundwater flow to optimize an artificial ground freezing (AGF) process.

Predicting Deformations in a Bank Protection Structure with Simulation

April 3, 2017

To predict how a bank protection structure within the Yangtze River in China would deform under certain conditions, a group of researchers turned to geomechanical analysis.

Which Porous Media and Subsurface Flow Interface Should I Use?

February 13, 2017

We go over a comprehensive selection of porous media and subsurface flow interfaces available to you in the COMSOL® software so that you can find the right choice for your modeling objective.

Improve the Productivity and Safety of a Perforated Well with an App

November 14, 2016

When designing a perforated well to recover oil and gas, choosing the right number of perforations with the appropriate properties is key. Too many holes and you run the risk of equipment failure or injury; too few and you decrease productivity levels. One way to achieve this balance and improve the safety and productivity of the recovery operation is to model fluid flow near the wells. Let’s see how the Application Builder makes this process even more efficient.

Applying a Hybrid Approach to Fracture Flux Conservation

September 13, 2016

Today, guest blogger and Certified Consultant Ionut Prodan of Boffin Solutions, LLC discusses using a hybrid approach to calculate fracture flux in thin structures. When modeling thin fractures within a 3D porous matrix, you can efficiently describe their pressure field by modeling them as 2D objects via the Fracture Flow interface. Significant fracture flux calculation issues, however, may arise for systems of practical interest, such as hydraulic fractures contained within unconventional reservoirs. See how a hybrid approach overcomes such difficulties.

Analyze Porous Structures with Numerical Modeling

May 31, 2016

Reservoirs, dams, and other outdoor structures need to be strong, reliable, and sound. The porous materials found within these structures can be easily damaged by pressure changes that cause fluid flow and gradual caving and sinking. Using the multiphysics simulation capabilities of COMSOL Multiphysics and the Poroelasticity interface, we can accurately analyze porous materials to evaluate and avoid deformation in such structures.

Investigating Damage to Cultural Heritage Sites with Simulation

May 3, 2016

Why are the famous paintings on the walls of a Netherlands chapel deteriorating? To answer this question, researchers from the Eindhoven University of Technology used physical measurements and simulation to evaluate how rising moisture affects the chapel’s artwork. Today, we’ll see how their research helped provide a better understanding of the damage occurring within this cultural heritage site.

How to Obtain Oil Cost-Effectively with Multilateral Wells

August 18, 2014

Safe and cost-effective drilling is a major issue in the oil and gas industry. In addition to the common prospecting risk, the borehole itself provides uncertainties that are not desired, but unavoidable. Today, we would like to show how numerical simulations can help here. The goal is to predict the stability of an open-hole multilateral well for deciding if the well will need expensive mechanical stabilization — or not.
