Petroceltic International plc has announced an operational update on development drilling on the Ain Tsila gas and condensate field in Algeria.
Development well AT-13, the second well of the Ain Tsila development drilling campaign, is located in the north of the field approximately 1.8 km from the appraisal well AT-8, and 6.1 km from the original discovery well AT-1. AT-13 is the second new development well on Ain Tsila expected to be required to establish and maintain the currently approved annual average wet gas plateau rate of 355 million ft3/d.
On 14 May 2016 the drilling reached a total depth of 2020m MD, having penetrated 73m of fully gas and condensate bearing Ordovician formation. Wireline logging results from the well indicate excellent reservoir quality. The well was drilled within scheduled time estimates and under budget.
The Sinopec Rig will now move to the AT-11 development well, located in the north of the field approximately 4.2 km from AT-8 and 1.8km from the AT-1.
