System and method of treating a subterranean formation with a diverting composition
A system and method for treating a subterranean formation. The method may include utilizing a diluted stream and a high-loading stream which are combined to form a diverting composition. The diverting composition may then be injected into a wellbore. The system may include devices to prepare the diluted stream and high-loading stream, combine the streams, and introduce the combined stream into the wellbore.
1. A method for pumping a diverting composition, comprising:
providing a diverting agent truck that comprises a batch mixer;
using the diverting agent truck to prepare, via batch mixing, a high-loading stream comprising a diverting agent, wherein the diverting agent comprises degradable fibers that are present in the high-loading stream at a concentration higher than 100 lb/1000 gal;
pumping a diluted fluid stream at a pressure between 60 and 120 psi to at least one plunger pump via a diluted stream line;
pumping the high-loading stream through a high-loading stream line to at least one high-loading pump;
combining the diluted fluid stream and the high-loading stream to form a diverting composition; and
introducing the diverting composition into the wellbore,
wherein the diluted fluid stream comprises a first amount of the degradable fibers, a gelling agent and water, and
wherein the high-loading stream comprises a second amount of the degradable fibers, a gelling agent, and water.
2. The method according to claim 1 , wherein the diverting composition is injected into the wellbore at about 50 bbl/min.
3. The method according to claim 1 , wherein at least one diluted fluid device that transports the diluted fluid stream to the at least one discharge line, and at least one high-loading device that transports the high loading stream to the at least one discharge line are each pumps.
4. The method according to claim 1 , wherein at least one diluted fluid device that transports the diluted fluid stream to the at least one discharge line, and at least one high-loading device that transports the high loading stream to the at least one discharge line are each ball injectors.
5. The method according to claim 1 , wherein the high-loading stream comprises a carrier fluid.
6. The method according to claim 1 , wherein the diluted fluid stream comprises a carrier fluid.
7. The method according to claim 1 , wherein the high-loading stream is transported at about 5 to about 10 bbl/min.
8. The method according to claim 1 , wherein the diluted fluid stream is transported at about 25 to about 65 bbl/min.
9. The method according to claim 1 , wherein the diverting composition is injected into the wellbore at about 30 to about 75 bbl/min.
