UPSTREAM oil and gas firm Invictus Energy Ltd has commenced the mobilisation of the Exalo Rig 202 to the Mukuyu-2 wellsite, as it prepares to start drilling next month.
In a recent shareholder update, Invictus managing director Scott MacMillan said rig mobilisation marked another milestone in the project as “we prepare to commence drilling the Mukuyu-2 appraisal well as a follow up from our highly successful basin opening Mukuyu-1/ST-1 well to confirm a discovery”.
“The Mukuyu-2 well will be located approximately 6,8 kilometres north-east from Mukuyu-1 and over 400m updip at the primary Upper Angwa target, which provides the potential to prove up a material discovery upon success,” said MacMillan.
He said Mukuyu-2 would be a near vertical well with a planned total depth of approximately 3 700m, which would also enable them to penetrate the untested Lower Angwa reservoirs in this location.
“The preparation of the well services equipment to be followed by independent QAQC ahead of mobilisation to the Mukuyu-2 well site is well underway and we remain on track to spud in September,” MacMillan said.
He said the Mukuyu-2 wellpad construction had been completed following the finalisation of civil works including pad levelling and compaction, water supply and reservoirs.
The well site has been inspected by the Environmental Management Agency and approved in accordance with the environmental management plan, the company.
Following the completion of the rig move to Mukuyu-2, Rig 202 will be rigged up and then undergo commissioning of the new mud tank system and rig acceptance, according to the firm.

Mukuyu-2 is targeting a prominent horst block within the greater Mukuyu structural closure.
The primary target interval, the Triassic Upper Angwa Formation, sits approximately 400m shallower at Mukuyu-2 than at Mukuyu-1.
This location will provide excellent information on the distribution and reservoir quality of Upper Angwa sands.
The well trajectory is planned to be near vertical from the surface location to provide optimal penetration of several stratigraphic intervals within the same structural horst block, while minimising operational complexity for both drilling and formation evaluation activities.
