Coiled Tubing With Real-Time-Measurement Tools Helps Overcome Stimulation Problems
The treatment in a deepwater, frac-packed well with fiber-optic-equipped coiled tubing (CT) and a rotating, hydraulic high-pressure jetting tool achieved successful stimulation of a 500-ft-long frac-packed zone after several previous failures using different techniques.
Novel Coiled-Tubing Perforation Technique and Stimulation in Carbonate Gas Well
This paper discusses a novel approach to abrasive perforating, including the first-ever use of an acid-soluble abrasive material and ending with CT-jetting-assisted nitrified stimulation.
Monitoring of Matrix Acidizing by Use of Resistivity Measurements
This paper describes the testing of a novel concept based on resistivity measurements to monitor acid-stimulation operations.
Tight formations are candidates for hydraulic fracturing as the default. However, the solubility of carbonate by various chemicals provides opportunities to extend the well drainage radius effectively without the intensive equipment, material, and infrastructure demand of hydraulic fracturing.
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.
