Removing Fines-Migration Formation Damage in the Putumayo Basin in Colombia
This paper summarizes a wide variety of sandstone-acid-stimulation case histories, highlighting aspects such as mechanical conditions and operational practices.
While there is increased scrutiny from regulatory and community stakeholders on the chemicals used in operations, complex and technically challenging reservoirs must be developed to replace reserves. Matrix stimulation remains a critical technology for delivering barrels at minimum cost.
CO2-Energized-Acid Treatment Reduces Freshwater Use, Boosts Well Performance
Carbon dioxide (CO2) with 30% foam quality (FQ) has been introduced for the first time during acid fracturing treatments in a tight, sour, high-pressure/high-temperature carbonate gas reservoir in Saudi Arabia.
Sandstone-Acidizing System Eliminates Need for Preflush and Post-Flush Stages
This paper presents experimental and field-case studies with a sandstone-acidizing treatment designed to retard the hydrofluoric acid reaction rate and enable single-stage treatment.
No-Damage Stimulation By Use of Residual-Free Diverting Fluids
This paper studied three residual-free fluid systems for acid treatments and fracturing in order to develop no-damage or reduced-damage and highly effective stimulation techniques for long-interval wells.
