Hammamet West-3 Well - Weekly Operations Update Report No. 10

Cooper Energy Limited (ASX:"COE") ("Cooper Energy") as Operator (and 30% joint venture interest) of the Bargou Permit, offshore Tunisia, provides the following operational update on the Hammamet West-3 well.

Well details :

Hammamet West-3 is located 15 km offshore and 1.6 km east of Hammamet West-2 in 54 metres water depth (see attached map). The nearest producing field is Maamoura, 12 km SW.

The well objective is to drill and test a highly deviated wellbore through the naturally fractured Abiod Formation reservoir to confirm oil productivity.

Activity at 06.00 hours

4 June, Tunisia time :

Running 7 inch casing liner to a planned depth of 3,032 mRT*.

Progress since last report :

The 9 5/8 inch casing was cemented in place and the 81/2 inch hole was directionally drilled to 3,032 mRT* at a 60 degree angle from

vertical. The top of the Abiod Formation was intersected at 3,010

mRT*.

Planned activities :

Cement 7 inch casing liner, test BOP's* and then directionally drill the 6 inch pilot hole through the Abiod Formation to a total depth of

3,438 mRT*.

Comments on well progress and outlook

As advised in previous announcements, the forward work program and anticipated cost of
Hammamet West-3 has been under review and is updated as follows.
The well has intersected the target Aboid Formation at 3,010 mRT which is approximately 40 metres TVD* high to prognosis. The current operation is preparing to drill a deviated pilot hole to a total depth of 3,438 mRT*. Prior to drilling ahead in the pilot hole the oil based mud system will be replaced by a water based mud system that will more easily allow identification of oil shows while drilling.

Upon completion of the pilot hole it is proposed to drill a 580 metre horizontal well targeting fractures in the Abiod Formation. A decision on production testing will be made upon completion of the horizontal well bore.
The cost to complete the well program is estimated to be US$44.8 million, with total duration of 100 days, exclusive of testing. The estimated cost to date is approximately US$31.6 million and 67 days have passed since the rig arrived on location on 28 March.
Cooper Energy's participation in the well is being carried to a total of US$9.4 million by Dragon Oil (paying 75% of US$26.6 million to earn 55%) and Jacka Resources (paying 30% of US$27.2 million to earn 15%). The revised well program is expected to entail a total cost to Cooper Energy of approximately US$4.0 million.
Weekly updates on well progress through the drilling campaign are provided to the ASX on each
Wednesday.
