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%
