The world at the time.

The company reported TEN more than 55% complete with all ten first-oil wells already drilled. It maintained the expected mid-2016 startup after the tribunal rejected a request to suspend exploitation.

What happened.

First oil flowed on August 18, 2016. The operator described the milestone as on time and on budget, while later production ramp-up was slower than expected.

The counter-signal.

Tullow’s February 2015 results described falling oil prices, cost reductions and suspension of its dividend. Those financial stresses made large remaining capital commitments a material execution risk.

Verdict.

Reasoning: sound · Outcome: right

August falls within an ordinary mid-year interpretation and matched the project’s announced schedule. The verdict is confined to first oil, because commissioning volumes subsequently missed expectations.

April 27 date checked on company page. Right scores first-oil timing only; mid-2016 is imprecise and should not be presented as an exact June deadline.

Cause of death / explanatory lens.

No cause of death assigned

The lesson.

How should a forecast separate first production from the more difficult ramp-up to stable capacity?
