2021 Hydraulic Fracturing Technology Showcase
2021 Hydraulic Fracturing Technology Showcase

To reduce ,fluid, loss encountered during the hydraulic ,fracturing, process, NatureWorks has released a new polylactic acid (PLA)-based degradable polymer called Ingeo DH1900 for downhole applications. Ingeo DH1900 can be pumped downhole as fine, discrete particles that quickly change into a thick, degradable material at the targeted site.
