... to accomplish this function, albeit with limitations. Functionally, these commonly used polymers depend primarily upon viscosity rather than elastic characteristics to suspend solids and require intensive chemical processing that leads to high deployment cost. Recently microfibrillated cellulose (MFC) has been...

... Abstract The detection of asphaltene precipitation and gas hydrate formation is critical to preventing production losses and to optimize strategies for mitigation and remediation. Likewise, the evaluation of some flow properties (e.g., viscosity and yield stress) of the slurries formed...

... as polymer injectivity tests. Rheological studies were performed on the biopolymer samples to measure the polymer viscosity as a function of concentration, shear rate, salinity, and temperature. Injectivity characteristics of this biopolymer were also examined through corefloods using high permeability...

... Abstract In the past, high-viscosity fluids have been the preferred method for increased proppant suspension and transport. This methodology has been effective using systems such as borate-crosslinked fluid with the downside of considerable damage to the proppant pack, typically resulting...
