Operations update

Tuesday, January 14, 2020

Vintage Energy Ltd (“Vintage”, ASX: VEN) is pleased to provide an operations update for its onshore Otway Basin, Galilee Basin and Cooper/Eromanga Basins drilling and stimulation campaigns.

Otway Basin (PEL 155, Vintage 50%)
Vintage is pleased to advise that a gas column with a minimum gross height of 65 metres has been identified at the top of the Pretty Hill Formation in the Nangwarry-1 well. The identification of this gas column was the result of combined wireline logging data and formation pressure measurements. The composition of this gas column will be confirmed shortly by laboratory analysis of samples acquired during logging operations. This data plus future testing will allow the estimate of the gross gas column to be refined. The further zone of shows previously reported in the mid-Pretty Hill Formation requires further evaluation and the joint venture will consider cased hole logging and flow testing strategies to fully evaluate this zone. Limited wireline log data to date does not indicate material volumes of moveable gas in this zone, however data quality has been impacted by hole conditions.

Further updates to the market will follow at the completion analysis of the evaluation program and determination of the gas composition.

Galilee Basin (ATPs 743, 744, 1015 (“Deeps”), Vintage 30%)
The operator of the Galilee Basin Deeps Joint Venture, Comet Ridge Ltd (“Comet”, ASX: COI), has advised that further modelling work has indicated that the original approach of stimulating down casing at Albany-1 ST1 is now preferred to the coiled tubing methodology reported last week. This change in plan will involve sourcing materials for downhole work prior to commencing stimulation which is now estimated to take place by the end of the month.

Albany-2 flow back commenced in December and was shut-in shortly afterwards whilst waiting on Nitrogen. Wellhead pressure built up to approximately 100 psi whilst the well was shut-in, indicating gas in the top of the wellbore. A laboratory sample was taken (to compare composition with Albany-1, located 7km to the northwest) and is currently being analysed. Further bulk nitrogen is booked to arrive on site later this week to continue to lift the remaining stimulation fluid from the well. The well will then be production tested.

Cooper/Eromanga Basins (ATP 2021, Vintage earning 50%)
Vintage, as operator of the ATP 2021 Joint Venture with Metgasco Ltd (25%) and Bridgeport (Cooper Basin) Pty Ltd (25%), advises that the Vali-1 ST1 gas exploration well reached a TD of 3,217 metres measured depth, in basement, on 10 January. As of 6:00am this morning the well was being conditioned for further wireline logging. Initial log analysis indicates that gas has been intersected in multiple sands in the primary Patchawarra Formation target. To date, this gas saturation has been calculated in the upper section of the Patchawarra, above the VC50 coal. Log data across the section below the VC50 is planned to be acquired at the conclusion of conditioning operations. This section exhibited strong shows and included some of the best quality sandstone samples whilst drilling.

The joint venture is currently considering the forward plan with respect to any further log and/or formation pressure evaluation with respect to the previously reported shows across the Nappamerri Group and potential pay in the Toolachee Formation. At the conclusion of this evaluation there will be a further update to the market.

Neil Gibbins, Vintage Managing Director, said “The evaluation results over the last week demonstrate the potential of the assets acquired by Vintage Energy. Since listing, Vintage has been involved in four wells, all of which have indicated gas. We now look forward to completing the evaluation programs at Vali, Nangwarry and Albany with the objective of confirming the potential we have seen to date and moving ahead with multiple projects”.
