NIGERIA: SIRIUS MOBILIZES COSL FORCE TO ORORO FIELD
Sirius Petroleum, the Nigeria focused oil and gas development and production company, is pleased to announce that the Company’s international rig partner COSL has now received preliminary Location Approval from the Marine Warranty Surveyor for the Ororo-2 and Ororo-3 wells and has commenced mobilisation of the jack-up rig for delivery direct to Nigeria.
Furthermore, COSL have optimised the drilling campaign for Sirius by electing to deploy the COSL Force jack-up rig as opposed to the COSL Power. The COSL Force is a “hot rig” (tooled-up and ready to operate) currently offshore UAE and is therefore ready to be mobilised to Nigeria shortly. The COSL Force is a state of the art rig which has a rated operating water depth of 375 ft and a rated drilling depth of 30,000 ft.
Once on station, it is anticipated, weather conditions permitting, that drilling of the Ororo-2 well will now commence in April 2018 and that drilling will be in a location close to the Ororo-1 well (originally successfully drilled by Chevron in 1986).
The Ororo-2 well is planned to penetrate all of the D sands, with the top three sands (D1, D2 and D3) being sampled and pressure tested. The objectives of the tests are to determine gas-oil contacts, the pressure regimes, fluid compositions, and in-situ gas-oil ratios ahead of an extended well test. The well will then be drilled down to the deeper G sands where it is expected to be completed for production.
Commenting, Bobo Kuti, Chief Executive, said: “We are delighted to be informed that COSL has finally secured the confirmation from the Marine Warranty Surveyor of the acceptance of the surface location of Ororo-2 and Ororo-3 wells enabling us to announce the mobilisation of the COSL Force jack-up rig. This is a milestone for Sirius as we embark with our operational partners on the first of our drilling programs. We are delighted to be working alongside COSL as our rig partners and thank them for the excellent work they have done on mobilisation and we look forward to the commencement of the well campaign operations on Ororo-2 in the coming months.”
