Abstract
Methods are disclosed for transporting viscous slurries, especially at high pressures, using fluid injection, especially steam injection.
Claims26
A method, comprising:
- providing a slurry at a first temperature and a first pressure, wherein said slurry comprises a liquid carrier and a solid;
- increasing said first pressure to a second pressure of about 50 psia to about 1250 psia, thereby forming a first pressurized slurry;
- injecting a fluid into said first pressurized slurry, thereby forming a fluid-injected slurry, wherein said fluid-injected slurry has a second temperature greater than said first temperature, and said second temperature is about 100° C. to about 300° C.;
- and
- increasing said second pressure to a third pressure of greater than about 1250 psia, thereby forming a second pressurized slurry.

A method, comprising:
- providing a slurry at a first temperature of about 1° C. to about 50° C. and a first pressure of about 14 psia to about 50 psia;
- wherein said slurry comprises a liquid carrier and a solid;
- and
- wherein said slurry has a viscosity of at least about 5,000 cP;
- injecting a fluid into said slurry to form a fluid-injected slurry;
- wherein said fluid-injected slurry has a second temperature of less than about 100° C.;
- and
- wherein said second temperature is greater than said first temperature;
- and
- increasing said first pressure to a second pressure of about 1000 psia to about 6000 psia, thereby forming a pressurized slurry.
