fracture interval was below 3,425 mTVD. Post job simulation indicates that the
fractures were contained, and did not extend beyond this point;
• The fracturing fluid used was water based;
• The volume of fluid pumped into the formation (discharge) was 280 cubic metres
(m³) with total proppant of 53 tons.
• The total duration of treatment was 83 minutes;
• In total, 313 m³ of fluid was recovered from the well post fracturing, in excess of
100% of the volume discharged. Returned
