Heritage Oil is to dig its Miran West-2 test well in Kurdistan deeper than originally planned after results proved much less productive than the adjacent test well.
Heritage said no hydrocarbons were flow tested to surface from the interval within Miran West-2 equivalent to that successfully tested in Miran West-1.
Miran West-2 will now be deepened to approximately 4,600 metres to explore further potential in the underlying Jurassic and Triassic structures, Heritage said. The drill has reached 2,600 metres so far.
The new exploration targets have the potential to contain substantial volumes of additional hydrocarbons, Heritage said. It expects that the drilling will take a further four to five months, following which the well will be tested.
“The further hydrocarbon potential in the deeper targets in the Miran structure has the potential to increase resources significantly,” Heritage chief executive Tony Buckingham said.
Separately, Heritage said the Ugandan government has given its agreement to the disposal of its 50% interest in Blocks 1 and 3A in Uganda to Tullow Oil for a cash consideration on closing of $1.35bn.
