DPE tastes gas at Dubai offshore well

15th October 2014

Dubai Petroleum Establishment (DPE), owned 100 per cent by the government of Dubai and responsible for the Dubai's offshore oil and gas development and production, has identified significant volumes of gas in its T-02 deep gas exploration well

The new well has been wireline logged to evaluate the potential of the formations and there are some 119 metres of gas rich zones out of the 274 metres drilled and logged in the Pre Khuff

The high pressure and high temperature T-02 well was drilled to 5,562 metres into the Pre Khuff formation and is the deepest well in Dubai to date. The well is in the offshore Fateh field where oil and gas was first discovered at depths of around 3,000 metres in 1966.

While drilling in the Pre Khuff, formation gas flowed into the T-02 well bore on a number of occasions. Current indications are that the gas is largely methane with no H2S content. An earlier well, T-01, was drilled into the Khuff formation in 1981 to a depth of 5,300 metres but test results indicated that significant levels of H2S and Nitrogen were present which made gas production and treatment difficult and expensive in an offshore environment.

The new well has been wireline logged to evaluate the potential of the formations and there are some 119 metres of gas rich zones out of the 274 metres drilled and logged in the Pre Khuff.

The well is currently being suspended to allow for later re-entry, stimulation and long term production testing. Until the testing programme has been completed, potential reserves and possible production rates cannot be estimated accurately. The planned production testing procedures require the use of specialist items and equipment that have long lead times for delivery. Currently, DPE expects to have the test results in late summer 2015.
