Method of fracturing using mannanohydrolase enzyme breaker |
| 摘要 |
A thermophilic mannanohydrolase enzyme may be used as an enzyme breaker for fracturing fluids containing hydratable polymers of guar and underivatized guar. The amino acid sequence of the mannanohydrolase is at least 90% homologous to the amino acid sequence of SEQ ID NO:2. |
