No joy for InterOil at Wahoo

Blowing cold: InterOil finds nothing at Wahoo-1 appraisal

The explorer is quitting the Wahoo-1 probe on PPL 474 after drilling to a measured depth of 1589 metres, it said on Wednesday.
The well was, however, not a total failure as Michael Hession said: “The well has increased our knowledge in an under-explored area. It has confirmed a working hydrocarbon kitchen, the presence of thermogenic gas and an effective seal in the Orubadi mudstone.
“Information obtained from the well will assist in evaluating future targets in this frontier area.”
InterOil resumed drilling in early June at the Wahoo prospect where higher-than-expected pressure and gas entering the wellbore halted a probe last summer.
The sidetrack was a follow-up to the problematic Wahoo-1 probe where progress was suddenly halted by a safety alert last July when InterOil unexpectedly struck gas well above its target zone.
InterOil had begun drilling at Wahoo-1, a multi-trillion-cubic-foot gas prospect, in early March last year. It ended up striking “significant concentrations” of methane, ethane, propane and butane.
