Improve the Productivity and Safety of a Perforated Well with an App
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
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
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
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
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.
AMPHOS 21 on Simulating Carbon Sequestration
According to AMPHOS 21, a COMSOL Certified Consultant, one of the proposed solutions to releasing carbon dioxide (CO2) into the atmosphere is to store the CO2 in geological formations, a technique referred to as carbon dioxide sequestration. This notion led the engineers at AMPHOS 21 to study the physical and chemical processes that occur during the injection of the gas into earth’s subsurface.
Coupling Heat Transfer with Subsurface Porous Media Flow
In the second part of our Geothermal Energy series, we focus on the coupled heat transport and subsurface flow processes that determine the thermal development of the subsurface due to geothermal heat production. The described processes are demonstrated in an example model of a hydrothermal doublet system.
Exploring Below the Surface with a Poroelastic Analysis
The Leaning Tower of Pisa is regarded as one of the most famous landmarks in the world, although geotechnical engineers probably view it more as a construction gaffe. To prevent such a leaning fate, it could be useful to run an analysis in order to predict possible subsidence due to poroelastic deformation.
