视频 Chemistry Solutions to Fuel Well Stimulation Performance
Juan Rincon discusses how advanced digital and chemical solutions drive enhanced well stimulation performance.
Efficient, low‑risk sandstone acidizing stimulation
OneStep EF sandstone stimulation solution for production and injection wells
Overview
A breakthrough in sandstone acidizing
OneSTEP EF™ efficient, low-risk sandstone stimulation solution is suitable for use in conventional injection and production wells with varying mineralogy complexities. This innovative well acidizing treatment restores initial permeability, provides fines migration control, and improves production performance in impaired sandstone reservoirs while minimizing the risk of further formation damage from precipitation.

Applications
- Production and injection wells
- Multilayer sandstone formations with high precipitation risk
- Simple to complex completion configurations
Benefits
Higher production with lower treatment volumes
By combining multiple conventional stages in one optimized stage, OneSTEP EF solution reduces total fluid volume by up to 50%. This translates to lower pump times and increased operating efficiency and safety. Flowback efficiency is improved particularly in gas wells where minimizing injected fluid promotes better production performance. This technology provides improved cost efficiency and performance in formations ranging from 65 to 310 degF.
Reduced operational risk
Lower number of stages, low precipitation risk, and low fluid incompatibilities.
Full reservoir coverage
Increased production and uniform stimulation across long zones.
Higher HSE performance
Reduced operational time, disposal volumes, personnel exposure, and associated emissions.
Greater efficiency and ROI
Lower cost per barrel through reduced mixing time and improved flowback efficiency.
Features
Reliable production performance
OneSTEP EF solution adapts reliably to complex, unknown mineralogies and provides the flexibility to be bullheaded or pumped through coiled tubing without acid preflush.
- Proprietary blend of acids and additives into a single-step formulation
- Acid-sensitive clay compatibility
- High calcium tolerance
FAQs
How does this acid stimulation technology work?
OneSTEP EF solution is a single-stage, low-volume, easily deployed acid stimulation solution that removes damage caused by drilling fluids, clays, carbonates, and other aluminosilicates.
What does this stimulation treatment replace?
OneSTEP EF solution replaces conventional sandstone stimulation treatments such as mud acid with acid preflush.
How does OneSTEP EF improve sustainability?
OneSTEP EF solution reduces wellsite operating time and footprint, improves flowback efficiency, and lowers related emissions without compromising well production performance.
