PERTH, Australia – Carnarvon Petroleum Ltd (ASX:CVN) says the Phoenix South-1 well has begun drilling a side track wellbore. On July 7, the well was drilling ahead at 1,960 m (6,430 ft) on the way to the 9-5/8-in. casing point of 3,700 m (12,139 ft).
As reported on June 23, a new side-track wellbore section of the Phoenix South-1 well was required to be drilled below the 13-3/8-in. casing depth, due to a stuck 9-5/8-in. casing hangar seal assembly running tool (casing tool). To retrieve the stuck casing tool, the upper portion of the previously set 9-5/8-in. casing was cut and retrieved along with the casing tool.
The original wellbore was plugged with cement, and the new side-track begun on July 5.
The new wellbore is being drilled 30 m (98 ft) from the original wellbore. The positioning and forward plans of the side-track wellbore do not compromise the evaluation of the Phoenix South-1 prospect, says Carnarvon.
The operator expects drilling to reach the target depth in mid-August and to complete well operations by the end of August.
The equity interest holders in the Phoenix South-1 well (upon satisfaction of the farm-in agreement terms) are Carnarvon Petroleum, 20%; operatorApache Energy, 40%; JX Nippon, 20%; and Finder Exploration, 20%.
