Prior to initiating DST #2, the casing was set in the well to a depth of 7,290ft (2,222 meters) short of total depth of 7,415ft (2,260) meters due to an impassable ledge.
The well was subsequently drilled an additional 213ft, from 7,415ft (2,260 meters) to 7,628ft (2,325 meters) and DST #2 was conducted with a packer inside the casing shoe over the 338ft (103 meter) open hole section from 7,290ft (2,222 meters) to 7,628ft (2,325 meters).
The company has planned to perform one more DST in the lower section of the current open hole, then drill and core from the current total depth into the targeted heavier condensate and potential oil zone where the company looks to perform additional DST’s and formation evaluation work.
Following testing and logging of the lower vertical section of the wellbore, InterOil has planned to drill a horizontal lateral to explore a potential oil zone.
Phil Mulacek, CEO of InterOil, said: “We anticipate that the higher condensate ratio tested in DST #2 of the Antelope structure will improve the previously estimated economics of the stripping plant proposed to be constructed in the Gulf Province.”
