Deep offshore fractured wells require high surface-treating pressure to achieve required bottomhole pressures for treatment. These pressures can reach frac-boat limits and need to be accurately ...

WITH increasing use of polyacrylamide gel in zone-electrophoresis, the need for rapid removal of excess stain from the gel increases. The conventional destaining of the gel by washing in 5–7 per cent ...

Traditional wellbore cleanout and plug-milling operations carried out through coiled tubing use fluids which have little solids suspension capacity, requiring high annular velocities to transport ...

SNF, a French producer of water-soluble polymers, will build acrylamide and polyacrylamide plants at Lukoil’s petrochemical site in Saratovorgsintez, Russia. Planned capacities are 50,000 metric tons ...

Continuing an investment program, SNF will expand its capacity for powder-grade polyacrylamide by 75,000 metric tons (t) per year globally by year-end 2020, largely to meet rising use of the product ...

Hydrogels, shown in Figure 1, are materials that are extremely soft and have a high liquid content. These materials have been recently used in numerous areas of clinical and biological research, for ...
