Tullow reported free cash flow of US$0.2 billion in its H1 2017 results. But an impairment charge weighed heavily on net earnings resulting in an after tax loss of US$309 million. Net debt was down 21% to US$3.8 billion (relative to year end 2016). With growth back on the agenda additional work is still needed to demonstrate that the East Africa projects are viable in a low oil price environment. Plans are underway to drill the Araku 1 high impact exploration well in Suriname and a commercial discovery would reinvigorate confidence in Tullow's exploration strategy.
