The evidence, from the 2008-14 period, shows that DHIs were far from being the holy grail with overall delivered success rates actually lower than the global benchmark. This has changed since 2014 though, and the success rates for prospects with DHIs has increased across the board.<\/p>\n

Commercial success rates (CSR) for all exploration wells increased 5% points in the 5 years after 2014 whilst for DHI supported wells they increased by 11% points and both are now 34%.\u00a0 In 2019 the CSR for DHI supported wells exceeded the global benchmark by 8% points.<\/p>\n

So, the underperformance has disappeared but what has been driving the improvement?<\/p>\n

DHIs improve success rates in stratigraphic trap exploration<\/strong><\/h3>\n

Westwood statistics show a growing appetite for stratigraphic exploration with over a quarter of all prospects drilled in 2019 being stratigraphic compared with just 12% of prospects in 2008. In this style of exploration effective DHIs are crucial. The CSR for DHI supported stratigraphic trap wells was just 7% in 2013 and lagged the benchmark for all wells targeting stratigraphic traps by 19% points.\u00a0 CSRs for DHI supported stratigraphic trap wells improved to over 50% in 2018 and 2019, comfortably outperforming the all well benchmark.<\/p>\n

The good news is that explorers are becoming more confident in their ability to search for the subtle trap. Combining consistently well-conditioned seismic data with sound geological models is the key to applying DHIs effectively.<\/p>\n
