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.
