The four metres pay zone was fracced on TB-23 in the prospective central-western portion of Linxing (West). Flow testing conducted over 5 days achieved a stable flow rate of 2.0 MMscf/day at a relatively stable flowing tubing head pressure of 1,250psi (approximately 2.36 MMscf/day calculated at standard field pressure of 200 psi).
The result represents the highest measured gas flow rate from a single fractured zone and is well in excess of the previously recorded maximum flow rate from the middle lower zone of approximately 230 thousand standard cubic feet per day. Seismic interpretation of the zone tested shows a high level of frequency across the acreage. Engineering planning is underway to connect the well into the pilot pipeline production program.
Commenting on the result Sino Gas Chairman, Gavin Harper said "This is a tremendous result, which comes after careful analysis and review to optimise fracture stimulation treatment in recent months. It is the third in a series of successful tests on Linxing (West), with others including testing of a lower level unstimulated zone at TB-26 and the nine stage frac testing of the first horizontal well at TB-1H."
