Ain Tsila Development: First Well Done, 23 More to Go

Irish minnow Petroceltic has released a “so far, so good” report of the first of 24 development wells on the Ain Tsila field.  “Wireline logging results from the AT-10 well indicate that reservoir quality is in line with the pre-drill prognosis, with an expected initial off-take rate comparable to AT-1 and AT-8 wells,  each of which delivered flow rates in excess of 30 MMscf/d on test”, the company says. “Well test results will be confirmed later in 2016 when planned batch completion, stimulation and testing activities are undertaken”.

AT-10 is located in the north of the field approximately 3.4 km from the field discovery well AT-1, and 2.0 km from the appraisal well AT-8. The 24 new development wells are expected to establish and maintain the currently approved annual average wet gas plateau rate of 355 MMscf/d.

AT-10 began drilling on 21 February 2016 and on 31 March 2016 it reached a total depth of 2005m MD, with a planned 61m penetration of a fully gas and condensate bearing Ordovician formation.

The Sinopec Rig is now moving to the AT-13 development well, located in the north of the field approximately 1.8 km from the appraisal well AT-8, and 6.1 km from the appraisal well AT-1.

AT-13 is targeting the Ordovician reservoir and will be drilled as a vertical well to a planned total depth of 2004m MD.

Petroceltic holds a 38.25% interest, Sonatrach a 43.375% interest, and Enel an 18.375% interest in the Isarene PSC. Petroceltic continues to benefit from a carry of its development costs in respect of Ain Tsila following the completion of the sale of an 18.375% interest to Sonatrach in July 2014.
