Formation Damage: Causes, Prevention, And Remediation
Formation Damage: Causes, Prevention, And Remediation
OBJECTIVES
- Recognize formation damage and damage mechanisms in carbonates, sandstones, and shales
- Prevent and overcome damage, when it exists, through the application of non-acid approaches, acidizing, and small fracturing treatments
WHO SHOULD ATTEND?
Production, completion, reservoir, and drilling engineers; geologists concerned with well performance and production enhancement; field supervisors, production foremen, engineering technicians, production and exploration managers; those involved in vertical, horizontal, and multilateral wells, conventional and unconventional reservoirs.
COURSE OUTLINE
- Geological/depositional environment, reservoir properties review
- Properties influencing formation damage
- Damaging sandstones, shales and carbonates, clay mineralogy
- Damage mechanisms and causes of damage: fluids and polymers, during drilling, running pipe and cementing, from perforating, during well completions, during production (fines migration, paraffin, scale, etc.), during workovers, and damage to injection wells
- Evaluating damage potential: laboratory testing
- Evaluating wells that may be damaged: production performance, pressure analysis, production logging
- Damage removal: non-acid approaches, acidizing, and bypassing damage with hydraulic fracturing
