Higher oil prices and good cost control lifted INPEX's quarterly operating earnings by 46% year-on-year. Financial performance continues to trend upwards since the start of the year, with operating cash flow up 21% for the first six months of the 2017/18 fiscal year. Results should continue to improve in the latter half of the year, following Brent's rise to US$60/bbl in November. INPEX upgraded its full-year operating earnings guidance by 10% as a result. The balance sheet is also showing early signs of improvement, with gearing down one percentage point since last quarter.
