Each one in plain English, with the numbers worked through for a shareholder.

7 July 2008production update▼ Bad

Galoc FPSO reconnection began 1 July, but the retrieval line was damaged in the typhoon disconnection and had to be replaced. No evidence yet of significant damage; first oil timing is still to be advised, after the earlier early-July target.

7 July 2008flow test result▲ Good

Incremental's release: Arpaci-2A's first zone (340-348m) flowed dry gas at 2.4 MMscf/d. Two shallower pay zones are to be added later, and surface facilities are targeted for mid 2009. Duplicate of Otto's release.

4 July 2008drilling result▲ Good

Incremental's release of the Arpaci-2A result: three potential gas zones between 160m and 350m, about 20m net gas sands, TD 525m. The lowermost zone (340-348m) will be flow tested shortly. Duplicate of Otto's release.

4 July 2008drilling result▲ GoodMajor

Arpaci-2A, the redrill of Arpaci-2 and last 2008 Edirne well, reached 525m and found three potential gas intervals between 160m and 350m, about 20m net gas sands on preliminary logs. Flow testing of the deepest zone is next (Otto 35%).

23 June 2008production update▼ BadMajor

Typhoon Fengshen forced the Galoc FPSO to disconnect on 20 June 2008, delaying first oil again. Reconnection is unlikely before 27 June and first oil is now expected in early July. Only minor commissioning work remains. Otto's interest is 18.3%.

16 June 2008well test result▼ Bad

Incremental's release of the Arpaci-1 test: water only from 236.8-240.9m, which it says does not affect commerciality. Rig moves to re-drill Arpaci-2 as Arpaci-2A, 30m north, the last 2008 well. Duplicate of Otto's release.

Discuss in chat

16 June 2008well test result▼ Bad

Arpaci-1, the 2006 well, produced only water on test, with no free gas, so it was not commercial. Otto says it sits at the structure's edge and does not hurt the Arpaci field's commerciality, which Arpaci-2 appraised. Arpaci-2A is next.

10 June 2008flow test result▲ Good

With added perforations, Kuzey Arpaci-1 flowed dry gas at up to 2.8 MMscf/d from several intervals between 404m and 468m, up from 1.15 MMscf/d. Arpaci-1 is tested next, then Arpaci-2 is re-drilled as Arpaci-2A (Otto 35%).

10 June 2008flow test result▲ Good

Incremental's release of the same Kuzey Arpaci-1 result: up to 2.8 MMscf/d from several intervals between 404m and 468m, with two more pay zones to add later. Duplicate of Otto's release.

4 June 2008flow test result▲ Good

Incremental's release of the Kuzey Arpaci-1 test: 1.15 MMscf/d from a 5m interval. It warns the Arpaci-1 test is uncertain, but says a wet result would not affect development plans. Duplicate of Otto's release.

Discuss in chat

4 June 2008flow test result▲ Good

Kuzey Arpaci-1 flowed dry gas at a stabilised 1.15 MMscf/d from just 5m (462.8-467.5m), the second commercial-rate flow in Edirne. More perforations will follow, then the older Arpaci-1 well is tested (Otto 35%).

27 May 2008investor presentation● Neutral

Otto's conference presentation in Sydney repeats known points: Galoc production imminent, 12 wells planned for 2008/2009, 477.3m shares on issue, about A$20m cash (30 April 2008) and about A$24m of Galoc debt. No new announcements visible.

27 May 2008flow test result▲ Good

Incremental reports Ikihoyuk-1 flowed dry gas at up to 3.8 MMscf/d from 444-453m, the best rate in the Edirne licence so far, from one of three pay zones. Kuzey Arpaci-1 and Arpaci-1 are tested next.

27 May 2008flow test result▲ Good

Otto's release on the 23-24 May test: Ikihoyuk-1 flowed dry gas at up to 3.8 MMscf/d from 444-453m, the highest rate from Otto's Edirne wells, from one of three similar zones. It supports plans for production by mid-2009 (Otto 35%).

15 May 2008drilling result● Neutral

Otto's release on Arpaci-2: gas found at about 169m, but the well was plugged for safety due to high pressure and will be re-drilled. The rig now tests earlier discoveries first. Otto holds 35% of Edirne. Same news as Incremental's release.

15 May 2008capital raising announcement● NeutralMajor

Otto placed 38.46m shares at 39c to raise $15.0m via Euroz. 14.7m shares issue now, 22.95m await FIRB approval, 0.77m to director John Jetter need shareholder approval. Funds go to Argentina, Italy, Philippine surveys and working capital until Galoc cash flow.

What it means for a shareholder

38.5m new shares at A$0.390 to raise about A$15.0m. That's 8.1% dilution: every existing holder's slice gets 8.1% smaller. If you held A$1,000 of shares (2,564 at the issue price), your slice goes from 0.000584% to 0.000537% of the company. To keep it you'd need 225 more shares - about A$88 at the issue price.

7 May 2008drilling spud▲ Good

Arpaci-2, fourth of five Edirne wells, has spudded as an appraisal well up dip of the Arpaci-1 discovery, to about 480m. Attached Incremental notice says six wells so far justify front-end engineering design, with first gas before mid 2009.

1 May 2008drilling result▲ GoodMajor

Ortakci-1 found about 20m of net gas pay, Otto's sixth Edirne discovery from six wells since 2004. It lies in the largest mapped structure, so it improves the outlook for western Edirne. Drilling and testing should finish by end June 2008 (Otto 35%).

Kuzey Arpaci-1, second Edirne well, found over 40m of net gas pay between 297m and 505m, more than double what was hoped. Otto calls it its fifth gas discovery in Turkey. The gas fields are close together and could share a central hub (Otto 35%).
