Buru Energy (BRU) has provided a market update on drilling operations at the Rafael 1 exploration well in the Canning Basin, Western Australia.
The Canning Basin is a geological unit in the southwest Kimberley region and Buru’s operations are dominated by rangelands with large cattle grazing properties covering the area.
BRU is drilling the Rafael 1 well targeting a mean prospective resource of 69 million barrels of oil.
Since removing the rig and undertaking a bit change and blowout preventer test, the company said the well has been circulated with increasing mud weight to control a gas influx which was encountered while drilling.
This news follows the company’s announcement last week that it had noted the presence of wet gas to light oil mud-gas shows.
In its efforts to ensure well bore stability is maintained, BRU has decided to implement a 7 inch (178 millimetre) casing before drilling continues.
According to the company, prior to running casing, wireline logs were obtained over the 8.5 inch open hole section of the well.
The logs are said to indicate the presence of vugular dolomite and zones where hydrocarbons are present, most likely wet gas, consistent with the gas measured at surface from the circulated influx.
While the logs and pressure data are subject to further interpretation, Buru said it provides encouragement for the continued drilling program prior to flow testing the well.
Shares were trading 3.6 per cent higher at 14.5 cents as of 10:00 am AEDT.
