Cooper Energy, operator of the Bargou Permit offshore Tunisia is ready to begin testing the recently drilled Hammamet West-3 well. The well is currently shut-in, with the next planned operation being the opening up of the production test string for a clean-up flow. It is expected that the production test period will be 4 to 8 days.
The first phase of the test will attempt to flow the well naturally and is expected to take 1-2 days. If the well fails to flow significant fluid rates to surface in the first test phase, it is planned to introduce acid into the well bore to stimulate fluid flow by breaking down any plugged formation caused by the drilling operations. This is a common practice in production testing fractured carbonate reservoirs. After flowing, the well is ‘shut-in’ and the reservoir pressure response determined. The ‘post-acidization’ phase of the production test is anticipated to take between 3-6 days.
