Cooper Energy discovers hydrocarbons offshore Tunisia

Hammamet West-3 is located 1.6km east of Hammamet West-2, in a water depth of 54 metres. The objective will now be to drill and test a highly-deviated wellbore through the naturally fractured Abiod Formation reservoir to confirm oil productivity, company sources have said.

The gas well has currently commenced drilling the horizontal side-track section in the primary target Abiod Formation limestone from 3,011 to 3,167 mMDRT.

The maximum total gas level recorded was 37 per cent, with onsite gas compositional analysis indicating the likely presence of oil.

Ultraviolet fluorescence was also observed in the drill cuttings over the interval 3,060 to 3,092 mMDRT, which indicated the presence of oil. The drilling mud weight at the time of the gas influx into the wellbore was 10.6 pounds per gallon (ppg) and it has been raised to 11.8 ppg, sources added.

Hector Gordon, executive director of Cooper Energy, said, “Although the drilling of Hammamet West-3 has taken longer than expected, the shows encountered in the horizontal well section are encouraging and, at this stage, appear to validate the pre-drill reservoir model.

“The best fractures identified by pre-drill seismic studies are yet to be encountered and we look forward to drilling these in the coming days. When the horizontal well section is complete, the joint venture may decide to conduct a production test which could take another 20 days.”
