Buru makes progress at Currajong-1 well

Waylering-5

Buru Energy has drilled the Currajong-1 well in Western Australia, with the Ensign 963 drilling rig performing well with minimal rig-related downtime.

The company has drilled ahead in 311mm hole from the 340mm casing depth of 713 metres to the current measured depth of 1952 metres.

However, Buru advised that the Ensign 963 rig faced an issue with the intermediate 13⅜-inch casing string which caused a number of days delay to drilling operations.

Operations related to the casing issue are planned to be completed shortly at which time a decision will be made on whether to install the contingent 9⅝-inch casing string before drilling ahead through the main objective section.

At the start of the month the company spudded the Currajong-1 exploration well.

The project is a 50:50 joint venture between Buru and Origin Energy, with the Currajong-1 exploration well being drilled on a large structure that is defined by 3D seismic.

The structure has a vertical closure of over 200 metres and is fault bounded with two way dip closure.

It is expected to have similar good quality reservoir and oil properties to the Ungani Oilfield and is at similar depths.

Currajong-1 is the first well in the exploration program under the terms of the farmin agreements executed in December last year, under which Buru would be carried for $16 million of the costs of the drilling of the two exploration wells in the program – Currajong-1 and Rafael-1.

Buru executive chairman Eric Streitberg said the company was delighted to be kicking off the most extensive drilling and seismic program in the Canning Basin.

“We are very pleased to be using a modern high capacity rig and we have worked diligently with the rig owners, Ensign Drilling, to ensure it is fully fit for purpose for the program before our final acceptance of the rig and the spud of the well,” he said.
