    The Operator, Cooper Energy (ASX: COE) has advised that production testing of the Hammamet West-3 commenced at 18.00 hours WST on Monday 5th August. The next planned operation on the well is opening up the production test string for a clean-up flow.
    As advised in the Weekly Well Update lodged with the ASX on 1 August, the production test will be conducted over the entire 432 metres of Abiod Formation drilled to date (Figure 1). The actual production test period is expected to be 4-8 days, depending on the flow rates recorded during the test. The first phase (1-2 days) of the test will attempt to flow the well naturally. If it proves necessary, after this first phase it is then planned to introduce acid into the well bore to break down any plugged formation caused by the drilling operations and to stimulate flow. This is a common practice when production testing fractured carbonate reservoirs. The subsequent main flow period (inclusive of shut-in) will occupy 3-6 days. After flowing, the well is “shut-in” and the reservoir pressure response determined.
    It should be noted that the well test equipment is limited to a maximum flow rate of approximately 3,000 barrels of oil per day.
    As the testing program is likely to continue throughout the week and the early flow rates are not necessarily indicative of the final flow rates after wellbore clean-up and/or acid stimulation the Joint Venture does not anticipate announcing the test results until the testing program has been completed. The weekly drilling updates will therefore be suspended.
