Electric submersible pump installed at Ungani

Buru Energy has successfully installed an electric submersible pump (ESP) in the Ungani 5 well in the Kimberly region of Western Australia.

The installation was to replace the current beam pump and was carried out to enable the fluid production from the well to be increased which, as prognosed, has resulted in an increase in oil production.

The installation was carried out using the Buru Jacking Platform which provides an innovative, safe, and cost-effective way to optimise and maintain the completions in the Ungani wells.

With all wells on production, field rates have previously been averaging some 800 bopd. The increase in rate from Ungani 5, and stabilisation of rates from Ungani 7, has now increased production to in excess of 1,000 barrels of oil a day.

The rate increase and the higher fluid volumes have been accompanied by a recent upgrade to the produced water handling system. This has successfully increased water handling capacity to that expected to be required for the continuing upgrades to the ESP’s in the existing wells, and the planned Ungani 8 well lifecycle.

The Ungani 8 well is planned to be drilled as a horizontal well into the potentially undrained fault block originally targeted by the Ungani 6H well using the rig being mobilised for the upcoming exploration drilling program.
