White Paper: Effective water-based drill-in fluid filter cake cleanup by treatment fluids containing organic acid precursors
10th January 2018
A discussion of laboratory and field experience
Generation of organic acid in-situ from acid precursors is now firmly established as an effective acidizing and filter cake treatment method.
This paper discusses the basis of in-situ organic acid generation and its applicability to the cleanup of water-based drill-in fluid filter cake. The literature on field use and laboratory evaluations is referenced and lessons learnt are highlighted.
