Speke South-1 reached 3,138 m in the interpreted Golden Beach Subgroup, but Apache sees no significant shows or signs of hydrocarbon pay on real-time logs. The prospect that carried BAS's 20% appears to have failed.
Speke South-1, the Apache-funded Vic/P42 farmin well, spudded on 7 April and is drilling at 334 m toward about 3100 m. Target is the Golden Beach Subgroup, with a 38.8 million barrel risked prospective resource. BAS is carried for 20%.
Weather and a mechanical fault on a support vessel have delayed the rig move to Speke South-1. Drilling will not likely start before next week. BAS remains free-carried with 20%.
Speke South-1 is waiting for better weather before the rig moves, so drilling should start early next week. Target is about 3100 m, with a 38.8 million barrel risked prospective resource. BAS stays free-carried with 20% and will issue twice-weekly updates.
Speke South-1 is now expected to spud around 26 March, to about 3100 m, with a 38.8 million barrel risked prospective resource. Windermere appraisal drilling in Q2 2008 now looks unlikely, with seismic reprocessing delayed; new seismic may come first. Both seismic surveys remain set for June.
BAS's review of the 1987 Windermere-1 oil discovery in 100%-owned PEP 167 supports an appraisal well, with drilling targeted for Q2 2008. Preliminary recoverable oil is 0.78/2.3/5.78 million barrels (P90/P50/P10). Unrisked value is stated as $57.5m-$92m; a partner is sought.
Apache proposes Speke South-1 as the Vic/P42 farmin well, testing an unrisked mean 36 million barrel prospect to about 2740 m, with drilling in March. It favours Speke South over the earlier SE Tarra target. BAS stays free-carried with 20%.
Apache's West Triton rig is being moved from Singapore, arriving by end January, so the Vic/P42 farmin well can start in March as its third 2008 Gippsland well. BAS stays free-carried with 20%. Final target not yet chosen from three surveyed sites.
Apache has committed to fund a Vic/P42 exploration well, now scheduled for March 2008 on the new West Triton rig. BAS is free-carried through drilling and testing and keeps 20%. The well earns Apache 60% and operatorship, firming up the earlier 'planned' well.
May 2007 Vic/P41 update finalises prospect mapping and says AVO anomalies resemble those at the Kipper field. Kipling P50 is 124 MMbbl oil, Benchley 184 MMbbl, Oscar West and East 19 MMbbl each. Unrisked prospects; farmin partners still sought, drilling not before early 2008.
May 2007 Vic/P47 update restates the Judith gas review: three appraisal areas, with prospective recoverable gas of 185 PJ and 413 PJ in two scenarios. Judith is likened to Longtom, where Longtom-3 flowed up to 77 MMscf/d. Partners still sought; prospective, not booked.
Farmin pack for Judith in Vic/P47 (BAS 40%, Moby 35%, Eagle Bay 25%) gives prospective recoverable gas of 185 PJ and 413 PJ in two scenarios. Partners are sought for 2008 appraisal drilling. Prospective, not booked.
Technical pack for the Vic/P41 Kipling prospect gives a P50 prospective oil resource of 124 million barrels, described as ready to drill in 2008. It is an unrisked prospect estimate, not a discovery, and supports the farmout pitch.
Recording of the 503 sq km Marie survey in Vic/P42 is complete, without incident. Processing finishes September/October 2007, with early data from June. This advances the Apache farmout toward a planned 2008 well.
Recording of the 503 sq km Marie survey began 12 March 2007 and is about half complete. Apache still plans a Vic/P42 well from early 2008, subject to prospect mapping.
The Western Trident survey vessel arrived at Vic/P42 and recording of the Marie 3D survey was expected to start within days. Apache plans a P42 well from early 2008, subject to successful prospect mapping.
The 503 sq km Marie 3D survey in Vic/P42 is due to start late February 2007, with Apache budgeting up to $20 million. BAS is fully funded. Apache then funds a well to earn 60%, leaving BAS and Inpex 20% each.
Oil Basins signed farmins with Eagle Bay (7.5%) and, via the Moby option, a further 5% of Vic/P41, for 12.5% in total. All pre-emptive rights were waived. BAS's 45% stays unchanged; this is a partner-level reshuffle, not a BAS farmout.
Partner Eagle Bay signed a deal letting Oil Basins earn 7.5% of Vic/P41, with a $500,000 backcost payment already made. Eagle Bay's stake would fall from 25% to 17.5%. BAS's 45% is unchanged; this adds a new partner.

Operator Essential Petroleum confirmed BAS will be assigned 25% of PEP 151, earned through the dry Pritchard-1 well. BAS will also earn 15% of PEP 150, which holds the Lindon oil discovery, by contributing to a future well on promoted terms. This resolves the pending Otway decision.
BAS and Inpex farmed out Vic/P42 to Apache, which will fund about 500 sq km of 3D seismic and one well, estimated at $25 million, to earn 60% and operatorship. BAS drops from 50% to 20%, fully funded through the well. This resolves the P42 farmout negotiations; it is conditional on approvals.
Joint venture partner Moby Oil & Gas granted Saxon Investment an option to earn 5% of Vic/P41 for $333,333, exercisable by 31 July 2006. This is a partner-level deal, not BAS's own farmout. The release lists BAS at 40%, against 45% elsewhere.
Pritchard-1 is a dry hole: logs showed the gas-bearing sandstones are water bearing, and the well will be plugged and abandoned. The operator notes good reservoir and seal were found, which it says supports further exploration.
Pritchard-1 reached 2240m, with background gas up to 500 ppm, which the operator says points to an active hydrocarbon system. No flow or oil result yet.
Pritchard-1 reached 1676m, drilling ahead at 12 to 15 metres per hour toward the Nullawarre Formation. Deepening continues as an operator-funded sole risk operation.
At 1419m, Bass Strait Oil and Inland Oil have met their funding obligations to the top of the Sherbrook Group plus 50m (1395m). Essential will deepen the well alone, with partners able to rejoin by paying costs plus a premium.
