High Efficiency Propping Technology

High Efficiency Propping

Using "cluster-like" structured support formed by the interaction of modified fiber, structural stabilizers, friction reducer, and proppants, it transforms proppant support from compact stacking to structured support. This enhances proppant placement, conductivity, and reduces sand and fluid volumes for cost-effective operations.

Core Product

Modified fiber

Dispersion

Complete dispersion

Proppant stacking volume increase rate

For 70/140 mesh quartz sand, the stacking volume increase rate is ≥60%.

Structural stabilizer

Stable performance.

Advantage

Increase effective support volume

Effective fracture length increased by 30%, placement height doubled, and contact area increased by 1.3 times

Enhance conductivity

"Cluster-like" structured support forms high-permeability channels, significantly improving fracture conductivity.

Cost reduction

Lower proppant pressure rating and particle size; a 40-60% reduction in scale does not affect placement height or conductivity.

Sand control

A 0.4% addition of suspended sand and drag silk can increase critical sand production velocity by 20-30 times, maintaining the stability and integrity of the sand barrier, effectively reducing proppant backflow, and enhancing long-term stable production.

Application Cases

Pilot and comparative tests were conducted in 12 domestic oil fields. By November 2024, the HEP had been applied in over 250 wells in domestic tight oil and gas, shale gas, and coalbed methane reservoirs. The average production increased by 20 - 30%, and the average sand production rate decreased by 60 - 70% compared to control wells.
