CNPC USA and CPET Downhole Win Hart Energy Meritorious Award for Engineering Innovation
UltraFrac™ HT technology recognized in the Hydraulic Fracturing / Pressure Pumping category.
Houston, TX, May 14, 2025 – UltraFrac™ HT Frac Fluid technology, invented by CNPC USA and applied by CPET Downhole, has received the 2025 Meritorious Award for Engineering (MEA) Innovation from Hart Energy.
The **Special Meritorious Engineering Awards for Innovation (MEA)** is recognized as the premier and most esteemed engineering awards program in the industry. Each year, it honors the most groundbreaking tools and techniques for discovering and producing hydrocarbons, judged by a panel of distinguished professionals on their transformative technical and economic impact.
Breakthrough Thermal Stability
**UltraFrac™ HT Fluid** is specifically designed for ultra-high temperature wells up to **230°C (446°F)**. The system achieves this industry-leading thermal stability through a unique three-component synergy:
- Synthetic Polymer: Primary gelling agent for robust viscosity.
- Zirconium Crosslinker: Provides stable network structures under stress.
- Multifunctional Additive: Simultaneously serves as a pH buffer, crosslinking delay agent, and temperature stabilizer.
Proven Field Performance
When fully broken, the fluid turns into a water-thin liquid with **zero solid residues**, enabling residue-free fracture cleanup and protecting reservoir permeability. The technology has delivered a **100% operation success rate** across 15 well treatments in the Qinghai, Daqing, and Tuha oil fields.
Key performance milestones include:
- Average friction-reduction rate exceeding **72%**.
- Cumulative fluid volume used exceeding **20,000 cubic meters**.
- Domestic records for the largest-scale fracturing job and highest pumping rate at 230°C.
