Transerv Energy prepares to start drilling two gas appraisal wells at Warro, Australia

Perth based Transerv Energy is set to start drilling in two pivotal appraisal wells at Warro, in Western Australia.

Claimed to be the largest undeveloped onshore gas field, the site is located 200km north to Perth.

Drilling at the Warro-5 and Warro-6 wells, which are being fully funded by Alcoa, will aim to explore gas from field which estimated to have a reserve of 8-10 trillion cubic feet of gas (TCF).

Transerv Energy executive director Stephen Keenihan said: "We believe this two-well programme is a unique proposition for investors, as it is seeking to prove up the largest onshore gas field in Australia.

"Moreover, this huge resource is located right next to key pipelines and on the edge of the biggest gas market in the country."

Transerv plans to drill the wells to a total depth of approximately 13,943ft rotary table (RT).

The drilling operations for each well are likely to take 40 days.

These two wells are expected to offer high gas flow rates and will help the firm to avoid the deep-seated faulting that might have caused excessive water encountered in previous wells.

According to 2012 review by US tight gas expert Keith Shanley, the new wells must be drilled in areas without deep-seated, old faults in order to minimise the water flow at the site.

Based on this review, locations for the Warro-5 and Warro-6 wells were found with the help of Warro 3D seismic.

Keenihan said: "We have confirmed the potential for this gas to flow at commercial rates.

"Now we are aiming to tick the last box by demonstrating that the gas can flow without the water issues by moving away from the deep-seated fault structures.

"The Shanley review found that this was likely to be achievable. If the impending drilling program shows this is correct, Transerv will be poised to become a major player in the WA gas market."
