President João Lourenço has signed decrees setting out specific terms to regulate the exploration and production of natural gas and halving tax rates for the development of marginal fields as the new government seeks to maximise earnings from hydrocarbons. The decrees were published in the Official Gazette on 18 May. The gas decree replaces the general principles that previously governed natural gas, under which associated gas had to be made available to Sonangol while non-associated gas could be developed on terms to be negotiated on a case-by-case basis.
