The adage “prevention is better than cure” is the first thing we consider regarding formation damage, but how prepared are we for the treatment and cure to allow a well to perform to its full productivity or injectivity potential? And how can digital tools

be an effective enabler? Our industry has made significant progress to improve our understanding of key formation-damage mechanisms and has developed best practices of laboratory studies and data evaluation to predict the formation-damage risk. These result in the development of preventive practices during various field operation (e.g., selection of suitable and compatible drilling and completion fluid system and additives). Despite all preventive efforts, some wells still experience formation damage that necessitates remedial treatment to restore production performance.

An effective and economic treatment of formation damage is critical, and we have observed great examples in the past few years of achieving these goals through development and application of innovative solutions by our industry experts and practitioners. Some highlighted efforts are immobile proppant systems for injector wells

as damage prevention, inhibitors with extended effectiveness to provide treatment longevity, and single-step sandstone matrix acid systems for operational simplification. While these technology advancements are delivering economic and effective solutions, there is opportunity to further improve prediction, prevention, and readiness for treatment with application and support of digital tools and solutions such as the following:

- Capture and application of learnings from historical laboratory studies to improve prediction capability of potential formation damage (fluid/fluid and fluid/rock interaction on the basis of their composition)

- Real-time data analysis and faster decisions with support from artificial intelligence during field operation to prevent and treat formation damage (e.g., intelligent real-time lost-circulation-event identification during drilling)

- Integrated information collection of all well-related data from laboratory studies to field operation for well life to enable efficient identification of sources of formation damage and effective treatment selection

Enjoy the papers chosen this year, some of which highlight my comments and encourage us to be proactive—not reactive—and better prepared for formation-damage treatment and cure.
