Whatever the model used to understand, model, and predict the injectivity of water injectors, its validation is always difficult because it is confronted with the lack of real field data such as pressures, temperatures, water quality, flow rate, flow conformance, for example. This is often true for deep water wells because each intervention to carry out a PLT or a simple thermometry to determine the flow conformance, could be long and expensive. One way to validate these models is to carry out laboratory tests under controlled conditions and different scales (centimetric to metric under stress or not) and under various injection regimes (matrix and/or frac). This is particularly interesting when dealing with unconsolidated reservoirs, which in addition to the validation of the models, original tests carried out in the laboratory should allow understanding of their behavior particularly in terms of frac and improving the physics implemented in the models which is still unknown. This session is dedicated to present and discuss this type of lab work and modelling approaches.
