UBC Oilfield Cementing Fluid Mechanics Group

 

 

 

 

Cementing services are an essential part of the successful construction of any oil and gas well, the maintenance of well productivity and the environmentally safe abandonment of the well. The 3 main operations are:

-         Primary cementing

-         Squeeze cementing

-         Plug cementing

The UBC cementing fluid mechanics group focuses on understanding the essential fluid mechanics behind these industrial processes: displacements, mud removal, instabilities and mixing, slumping flows, etc… The group embodies over 10 years of experience with oilfield fluid mechanics.

Our research methodology combines mathematical analysis, computational fluid dynamics studies, pilot-scale experiments and visualization. We are experienced in delivering our knowledge in a format that is useful for industrial engineering design and in understanding where and how the processes may fail. Results and analysis from the UBC group are embedded in the design software of at least one major cementing service company. 

Areas of study:

-         Annular displacement flows of non-Newtonian fluids

-         Static wall layer formation in non-Newtonian displacements

-         Reactive spacers for extended reach horizontal cementing

-         Stability of cement plugs placed off-bottom

-         Slumping flows of horizontal cement plugs
