Three drill stem tests were undertaken on the well. The main target Pab sandstone was encountered at prognosed depth; however, the formation was tight and no gas flow was obtained. A second test of the overlying Ranikot formation produced gas to surface as did a third test over the Dunghan formation, which flowed at a maximum rate of 6 million cubic feet of gas per day.
Several undrilled structures lie close by in PKP's acreage. One, the Chung prospect, lies mid-way between Zirkani-1 and the recently developed Bhit field. Recent negotiations have enabled PKP to acquire more of the acreage that contains this prospect, now allowing it to be a candidate for drilling. In the event of future drilling success in the area, the Zirkani-1 discovery will be considered for integration into a new development. Studies of the reserve potential of Zirkani have commenced.
Following the recent drilling on the Dumbar license, Premier believes that the exploration potential on the block remains attractive. A detailed technical review of the results of the wells will be undertaken before determining the way forward.
Charles Jamieson, CEO of Premier Oil, said: 'The two recent wells drilled in our Dumbar block have confirmed the presence of gas and studies of the reserve potential of Zirkani have commenced. We believe that the block has further exploration potential in identified prospects and we are now formulating our forward plan using the information gained from the wells.'
