The company has now contracted the Simmons Rig #3, a heli-portable conventional oilfield rig, which is currently being mobilised and is expected to begin drilling on Sterling Mustang in October.

InterOil is also in discussions to contract other rigs by the end of the year for drilling additional wells on other prospective structures and to drill appraisal or development wells as needed.

Testing and appraisal drilling on the successful Moose structure secondary target is expected to follow the completion of current drilling and coring activities.

Two separate drill sites are being prepared to drill the first appraisal wells on the Moose structure and will enable the company to delineate the extent of the potentially productive limestone.
