August 25, 2014

Santos hit a gas discovery at the Lasseter-1/ST1 exploration well, offshore Western Australia.

The block and its surrounding areas are considered an area of high exploration potential.

The drilling, which began in March 2014, found the hydrocarbon pay assessed to be approximately 80m thick in total.

From a preliminary evaluation of wireline log data, joint venture partner Inpex confirmed the hydrocarbon pay in a 400m long gross gas condensate section. Gas and condensate samples from the well were recovered by Inpex that reached its target depth of 5329m.

The Lasseter-1/ST1 well in block WA-274-P, located approximately 500km north-northeast of Broome, Western Australia. The drilling, which began in March 2014, found the hydrocarbon pay assessed to be approximately 80m thick in total.

The block and its surrounding areas are considered an area of high exploration potential.

Sanots and JV partners will analyze and evaluate data obtained from the Lasseter-1/ST1 exploration well and study the possibilities of commercial development.

Santos is the operator of WA-274-P with a 30% interest with joint venture partners Inpex (20%) and Chevron (50%).

WA-274-P is located 50km west-northwest of the Ichthys gas-condensate field where Inpex says it will proactively pursue exploration activities in the 11 exploration blocks located in the vicinity of the Ichthys gas-condensate field to enhance exploration and production activities.

The Ichthys field, located in the Browse basin in the Timor Sea, approximately 200km off Western Australia and 800km southwest of Darwin, is comprised of two hydrocarbon reservoirs, Brewster and Plover. The field is estimated to hold 12.8Tcf of gas and 527MMbbl of condensate.

According to Inpex, the project’s next major milestone will be the turret installation.

In July, Inpex launched the hull of its Ichthys FPSO form Daewoo Shipbuilding and Marine Engineering yard in Okpo, South Korea

The Ichthys LNG project is scheduled to begin production by the end of 2016, with gas sourced from the Ichthys gas and condensate field in the Browse basin. The FPSO will be moored around 3.5km from the project’s central processing facility. It will be transported through a subsea pipeline more than 885km to a proposed processing plan in Blaydin Point in Darwin’s Middle Arm Peninsula.

Ichthys will have an initial capacity to produce 8.4mtpa of LNG, 1.6mtpa of liquefied petroleum gas, and approximately 100,000b/d of condensate at peak production.

Construction started on the US$34 billion Ichthys LNG project in April 2012, just months after final project go-ahead was granted in January 2012.
