Helium One Global said that third-party legal complications, affecting time and availability, had prompted it to choose a new company for the drilling rig at its 100% owned Rukwa licence in Tanzania.
EXHALO DRILLING RIG
The company is on course to begin the Phase II drilling programme in Q1 2023.
Helium One had previously chosen the Epiroc Predator 220 rig but has now signed a non-binding memorandum of understanding with Exalo Drilling S.A., with final negotiations nearing completion.
The Exalo rig had been the company’s original choice but was at the time unavailable.
Helium One added that using Exalo for the drilling programme was not expected to increase costs materially compared with the Epiroc Predator 220 rig.
The rig, which can be dismantled into 28-tonne loads for quick mobilisation, will mobilise after completing its current operation in southern Africa.
Teams will transport the rig along with the Baker Hughes integrated service package currently in use at the same location.
Exhalo provides onshore drilling rigs and associated services with a fleet of 35 land rigs capable of drilling up to 8,000m in depth.
ECONOMIC DISCOVERY
Chief executive David Minchin said that the rig had a larger 1200HP powertrain which would minimise the risk of downhole and operational issues when it drills the Tai prospect.
It would also ensure that the company has the best possible chance of identifying an economic helium discovery at Rukwa.
LICENCE RENEWALS
In September, Helium One reduced its licence footprint by 1,548 km2.
The company has now renewed 14 of 18 licences licences which were due for second renewal during September and October 2022.
The licences cover more than 2,500km2 in the Rukwa, Eyasi and Balangida project areas.
