Horizon Oil advises that drilling was completed on the first of two exploration wells in the Beibu Gulf Block 22/12. This exploration drilling program follows up on earlier exploration discoveries and the subsequent successful development of the WZ 6-12 and WZ 12-8W fields carried out in 2012 and 2013, which have already produced over six million barrels of oil. The well is located 4.7 km northeast of the existing WZ 12-8W platform and approximately 2.7 km west of the WZ 12-8E discovery wells (see map).
The WZ 12-10-1 well has discovered oil in the top of the Jiaowei T42 formation over an interval of 5.5 m, with high porosity net oil pay of 4.2 m.
