| Abstract: | In order to predict the fracture propagation of drilling cuttings re-injection offshore. Taken initial filtrate loss and following filtrate loss into consideration, the fracture propagation model was forward and solved, using material balance method. A concept formation model was built and solved with both material balance method and professional software FracproPT. The results showed that the errors of length and width of the fracture predicted by the two methods were 5.3% and 8.9%. The method could provide evidence for fracture propagation of drilling cuttings re-injection. |
| Keywords: | cuttings re-injection fracture propagation material balance method filtrate loss |
