Vintage faces delays following border closures

Vintage Energy has reported that design and planning for the Nangwarry-1 flow test program has been completed, with procurement of long lead items for the Otway Basin project onshore South Australia underway.

Due to the border closure between South Australia and Victoria, mobilisation timing of the Superior Energy snubbing unit, the workover rig that will used for the Nangwarry-1 test work, was impacted.

Vintage advised that Nangwarry-1 testing would now begin at the end of January/early February 2021 as a result.

The testing program will include a short test of the mid-Pretty Hill Sandstone, which will be followed by a move into the shallower zone and a flow test of individual sands in the interpreted carbon dioxide (CO2) column at the top of the Pretty Hill Sandstone.

The test will be completed once a desired stabilised flow rate and volumetric estimate of the recoverable CO2 is obtained.

Vintage managing director Neil Gibbins said: “The uses for CO2 cover a broad spectrum of industries and have now been added to with the recent announcements regarding the substantial cooling requirements for worldwide storage and handling of vaccines such as the Pfizer Inc/BioNTech COVID-19 vaccine.

“This version of the vaccine requires it to be kept at temperatures of at least minus 70 degrees Celsius which will require significant amounts of CO2 in the cold storage process. This is just another reason we are pushing as hard as we can to successfully test this well and move the Nangwarry project toward commercialisation.”

Vintage has also faced delays completing the Vali-1 ST1 well in the Cooper Basin as a result of the border closures.

Despite the delays, the company is confident that the completion process will begin around December 12, 2020.

The company reported that the delay would not change the timing of the tie-in of the Vali-1 ST1 well to the Moomba gathering system or future wells expected to be drilled in the Vali field.
