Table 3
A summary of breakdown pressure and breakdown time obtained from fracturing with distilled water and thermochemical.
| Borehole diameter | Breakdown pressure with water (psia) | Breakdown pressure with thermochemical (psia) | Volume of water injected (ml) | Volume of thermochemical injected (ml) | Percentage reduction in breakdown pressure | Breakdown time with water (mins) | Breakdown time with thermochemical (mins) | Percentage reduction in breakdown time |
| 1/4 inch | 1359 | 835 | 16.8 | 13.55 | 38.5% | 3.36 | 2.71 | 19.3% | 3/8 inch | 1157 | 457 | 15.915 | 13.15 | 60.5% | 3.183 | 2.63 | 17.3% |
