Polyelectrolyte Multilayered Nanoparticles as Nanocontainers for Enzyme Breakers During Hydraulic Fracturing Process
Available to PurchasePublisher: Society of Petroleum Engineers (SPE)
Paper presented at the SPE Annual Technical Conference and Exhibition, September 21–23, 2021
Paper Number: SPE-205981-MS
... as enzyme viscometric assays. Controlled release of enzyme entrapped within PEMs was sustained over longer time periods (> 18 hours) through reduction in viscosity, and elastic modulus of borate-crosslinked hydroxypropyl guar (HPG). Long-term fracture conductivity tests at 40℃ under closure stresses...

Rheology, Regain Fracture Conductivity and Viscous Fingering Phenomenon for Proppant Suspension in CMC Hydraulic Fracturing Fluid
Available to PurchasePublisher: Society of Petroleum Engineers (SPE)
Paper presented at the SPE Annual Technical Conference and Exhibition, October 9–11, 2017
Paper Number: SPE-189278-STU
... compared to the conventionally used guar gels made from the hydroxyl propyl guar (HPG) thickener. It was also found that CMC was able to withstand considerable viscosity at elevated temperature of about 90 degrees Celsius. Images from the Scanning electron microscope (SEM.) showed that CMC's microscopic...

Rheology and Molecular Structure of HPG Gels
Available to PurchasePublisher: Society of Petroleum Engineers (SPE)
Paper presented at the SPE Annual Technical Conference and Exhibition, October 5–8, 1986

... zone. The gel viscosity is required to prevent solid propants from settling during the pumping operation. HPG crosslinked with Tyzor AA, an organotitanate composed of titanium σomplexed with acetyl acetonate, meets these criteria and will be the material investigated in the subsequent portions...
