Nangwarry Field Update
Melbourne, July 12, 2021 AEST (ABN Newswire) - Vintage Energy Ltd (
ASX:VEN) is pleased to provide an update on the resource estimate of the on-block recoverable carbon dioxide ("CO2") sales gas from the Nangwarry Field in the onshore Otway Basin.
- Independent resource estimate confirms sizeable CO2 sales gas resource
- Gross recoverable CO2 best case of 25.9 Bcf (12.9 Bcf net)
- Production test confirmed raw gas flow rates well in excess of commercial requirements
- Joint Venture appoints Vintage as marketing agent to commercialise Nangwarry Field
A revision of the Nangwarry Field recoverable estimates* has been conducted by ERC Equipoise Pte Ltd ("ERCE") following the successful production test of the Nangwarry-1 well.
Nangwarry-1 was perforated across the Top Pretty Hill Formation and produced raw gas (~93% CO2, ~6% methane and ~1% nitrogen), at higher than anticipated raw gas flow rates of 10.5-10.8 million standard cubic feet per day ("MMscfd"), measured through a 48/64" choke at a flowing wellhead pressure of 1,415 psi over a 36-hour period. This flow was measured through a 3" orifice plate and choked back to analyse the well over this extended flow period with stable conditions. The well is very productive, with a raw gas flow rate of only 3 MMscfd required to supply a purification plant capacity of 150 tonnes per day.
The Nangwarry Field has the potential to provide a stable and reliable source of food grade CO2, which is currently in high demand since the depletion of onshore Otway Basin well Caroline-1 in 2017. The main industrial uses for food grade CO2 include:
- Carbonation of soft drinks, fruit juices and beer
- Recharging of natural mineral waters
- Winemaking
- Tapping beer and oxidation prevention through contact with air
- Conservation of wine, unfermented grape juice and fruit juices
- Medical devices
- Cold storage / refrigeration
- Accelerating growth of farm produce as an atmosphere additive
- Preparation of sodium carbonate, alkaline bicarbonates, lead carbonate and various organic substances (e.g. salicylic acid)
- Production of paints and varnishes and manufacture of foam rubber
Since the successful drilling and testing of Nangwarry-1, the Department of Energy and Mining approved an application for a retention licence over the Nangwarry CO2 discovery, prior to expiry of PEL 155 on 5 May 2021. As a result, the Joint Venture retains a significant amount of land around the Nangwarry Field while it pursues options for commercial development.
Vintage has been appointed by the Joint Venture as the marketing agent to commercialise the Nangwarry Field. The recent appointment of an in-house Commercial Manager, along with BurnVoir Corporate Finance Limited as a corporate advisor, provide the appropriate resourcing to investigate and negotiate a beneficial outcome on behalf of the Joint Venture for commercialisation of this excellent resource.
