CONTROLLING DEGRADATION RATES OF DIVERTING AGENTS |
| 摘要 |
A treatment to temporarily block highly permeable areas in a wellbore having a temperature of less than 160° F. A diverting agent, a catalyzer, and a viscosifier are mixed together and pumped in the wellbore where the treatment flows in the most highly permeable areas. The diverting agent then begins to block those areas as the well is treated finally causing the fluid to divert to other now more highly permeable areas of the wellbore. After less than 48 the diverting agent degrades sufficiently to restore the permeablility of the wellbore. |

1. A fluid system for treating a well comprising:
a diverting agent,
wherein the diverting agent is a solid urea derivative,further wherein the diverting agent is present in an amount from about 0.625 percent by weight of the fluid system to about 1.25 percent by weight of the fluid system, a viscosifier, and a catalyzing agent. |
