KARACHI: The Pakistan Petroleum Limited (PPL) announced discovery of gas from Exploration Well, Naushahro Firoz X-1 in Naushahro Firoz Block, Sindh.

In a filing with the stock exchange on Wednesday, under the disclosure of ‘insider information’ in terms of section 15D(1), the PPL reminded that it holds 90 per cent working interest in the well.

M Mubbasshar Siddique, company secretary for PPL, stated that the exploration well at Naushahro Firoz X-1 was drilled down to target depth of 3,773m(MD) within Chiltan Formation.

Based on gas shows encountered during drilling and wire line logs evaluation, a cased hole drill stem test (CHDST) was carried out.

The PPL informed that after acidization, the well flowed good quality gas at variable rates with the maximum of 11.2mmscfd with a flowing wellhead pressure of 2,635psi and a minimum of 1.7mmscfd with a flowing well head pressure of 375psi at a choke size of 32/64 inches.

PPL observes: “Preliminary analysis of the test data suggests the discovery to be the tight gas. However, further evaluation is required to determine the nature and commerciality of the discovery based on the geological, geophysical and engineering data collected during the drilling and testing of the well and also by drilling of additional well(s)”.
