Typical Properties and Field Applications
E‑Frac technology was commercialized in 2019 successfully and has been applied in various oil and gas fields in the world. It has been proved to be effective in treatment of tight sandstone and carbonate reservoirs with the following conditions:
|
Temperature: |
BHST 70‑275°F (21‑135°C) |
|
Formation: |
Various sandstone and carbonate formations |
|
Mix‑water: |
Fresh water, some brines or seawater |
Precautions and HSE Considerations
Guar (KHF021 and KHF021L), delayed crosslinker (KHF008, KHF009, KHF009L and KHF020), foaming agent (KHF022) and breaker (KHF011, KHF012, KHF013 and KHF014) in E-Frac systems play the most important roles in fracturing fluid and treatment design. In addition, clay stabilizer (KHF002L), biocide (KHF003), stabilizer aid (KHF004) and flowback additive (KHF007S) are often used in E-Frac systems.
The laboratory procedures, quality assurance program and guidelines for field mixing and handling of E-Frac systems are described in E-Frac fluid manual.
