Partner Sun Resources says the L20/50 joint venture has committed to a second firm well, with a third contingent. Peak Oil & Gas will carry Sun's A$1.3m share of the first well to earn 7.5%. Largely repeats Carnarvon's own update of the same day.

26 Nov 2010drilling progress report● NeutralMajor

WBEXT-1A's 3,000 bopd test rate has been choked back to 200 bopd because of water, and WBEXT-2ST2 stopped flowing, possibly separate from the WBEXT-1 pool. WBEXT-1C is producing 3,500 bopd; L33 wells began selling on 20 Nov (1,450 bopd combined). Management still expects 1-1.5 MMbbl annual guidance to be met.

3 Nov 2010resource reserve update▲ GoodMajor

Independent estimate (GCA) puts contingent resources over the new WBEXT and L33 discoveries at 10.3 million barrels net (2C) and prospective resources at 4.5 million barrels net. Carnarvon expects year-end reserve additions to more than offset the expected NSE-F1 downgrades; WBExt-1C to be drilled.

27 Aug 2010drilling progress report▼ BadMajor

WBEXT-1 has averaged 3,360 bopd gross over 15 days of its 90-day test; WBEXT-1A is setting casing above a deeper volcanic zone. Bo Rang B results matched expectations, but NSE-F1 appraisal will likely cut its 2P to under half of 4.8 million barrels net and remove all 3P.

24 Aug 2010farm in farm out agreement● Neutral

Partner Sun Resources signed a term sheet for Peak Oil & Gas to earn up to 20% of L20/50 by carrying up to US$3.43m of Sun's well costs. Sun keeps at least 30%; Carnarvon stays 50% operator, first firm well planned December quarter 2010.
