Helium One Global Ltd - Helium One will shortly be drilling at Rukwa, and this time with its own, specialist rig
Shares in Helium One Global Ltd (AIM:HE1, OTCQB:HLOGF) jumped by not far short of 100% early in July after the company announced the acquisition of a drill rig.
Ownership of the rig will allow the company it to set its own terms when it comes to drilling the potential huge Rukwa project in Tanzania later this year.
Hitherto, rig availability has been tight, and getting the right kind of rig for the job has been even trickier.
“Everybody recognised the challenges we faced in Tanzania getting an oil and gas type drilling rig,” says Lorna Blaisse, who was appointed chief executive of the company in February.
Prior to her promotion, Blaisse was Helium One’s principal geologist, so perhaps more than anyone she knew what was at stake, following the mixed results of the first round of drilling.
“We knew that going into the second round of drilling we would need to have a robust rig,” she says.
“The sale of this rig came onto our radar a couple of months ago and we acted quickly.”
Previously Helium One had stated its intention to start a new round of drilling by the end of the third quarter of this year, and the acquisition means that that deadline will now be met.
The rig is due to arrive at site shortly, and the expectation is that the Tai-C well will be drilled in September.
Crucially, unlike the rig used in the last campaign, this new rig is one that was designed for use in the oil and gas industry.
The most obvious difference between this rig and a mining rig that was used before is that it is much more powerful.
Mining rigs are primarily designed to bring up core from large ore bodies in competent rock, which means that the borehole diameter is a much slimmer design. Conventional oil and gas wells are drilled with a wider borehole diameter, as they typically drill through softer rock, and a larger hole diameter is required to improve wellbore stability.
The new Helium One-owned rig will drill the target reservoir section in standard 8.5inch hole, as opposed to the 3.5inch hole drilled in the previous round of drilling. It is a larger rig with a top drive system and, can therefore drill more efficiently.
The new rig is capable of drilling down to depths of between 2,000-metres and -2,400 metres, although the Tai prospect that Helium One is aiming for is reckoned to sit at around 1,200 metres.
The plan is to spend 30 days drilling, including logging and down-hole sampling, and then to wrap it up and assess the results.
