Rupture-resistant filter cakes for wellbore strengthening – Nikzad Falahati

Lost circulation during the drilling process is estimated to cost 2 to 4 billion dollars annually, due to non-productive time and the loss of expensive drilling mud materials. Wellbore strengthening techniques have been developed to maintain the integrity of the wellbore, preventing lost circulation through fractures, but current techniques produce practical difficulties. This study aims to use the filter cake that naturally forms on the internal surface of the wellbore to produce a rupture-resistant seal across the fractures. This will be achieved by investigating the influence of drilling mud constituents on filter cake properties, and, by understanding how the mechanical properties of the filter cakes can be optimised.

Simulator of underground water flow and transport processes – Jan Hybs

The purpose of this talk is to briefly introduce numerical software Flow123d – a simulator of underground water flow, solute and heat transport in fractured porous media. The software supports computations on complex meshes consisting of simplicial elements of different dimensions. The talk will describe future goals in HPC (high performance computing) and CI (continuous integration).
