Sino Gas & Energy Holdings Limited says that a gas flow rate of approximately five million standard cubic feet (MMscf) per day has been achieved on the first horizontal well of the Linxing Production Sharing Contract (PSC).

The first horizontal well, drilled in late 2013, has been fracced in a five metre middle level zone in the south- western discovered area of Linxing (West).

Following a nine stage fracture stimulation treatment, flow testing was conducted over 80 hours in two stages, achieving a gas flow rate of 4.93 MMscf/day at a relatively stable flowing tubing head pressure of 2,008 psi (over 8 MMscf/day calculated at standard field pressure of 200 psi). Pressure build-up testing was conducted in between the two testing phases for eight days, with initial results indicating an estimated formation pressure of 3,116 psi.
