Well treatments based on polymers and microgels.
Optimization of the effectiveness and of the durability in the context of the sand production control - ABSTRACT - Most of the problems related to well productivity, especially in gas storage issues, result from sand and or water inopportune production.
The fines, transported at high velocity by gas, have a very powerful abrasive capacity, involving an accelerated degradation of the equipments. Microgel or polymer treatments have shown their capacity to restore well productivities. However, the understanding of the main mechanisms related to the productivity enhancement are still lacking. The objectives of the research work is to investigate experimentally the cause of fines particles erosion and the interactions with polymers and microgels in order to optimise and to increase the durability of the treatments. The work will be based on flow in rock plugs to characterise particles erosion related to the nature of the rock types. Small scale visualizations are also needed to understand the relations between micro and macro scale.
