Repsol and partner Woodside have discovered oil in the Ivela-1 exploration well in the Luna Muetse (E13) block offshore Gabon.
This is as Eni also finds oil at Kalimba in southern part of prolific offshore Angola block 15/06.
The Gabon well intersected a 78-m (256-ft) gross oil column, a month after a Petronas discovery in presalt sands in the Boudji-1 well in the nearby Likuale (F14) block.
In a separate development, Spectrum and Shearwater GeoServices have signed an agreement concerning provision of Shearwater Reveal software to Spectrum’s seismic imaging division.
Reveal is said to facilitate rapid testing of advanced workflows and parameter selection, which improves productivity. The programming interface will allow Spectrum to insert its own proprietary technologies into the same environment for seamless workflows.
The Kalimba-1 NFW well, drilled by the drillship West Gemini in 458 m (1,502 ft) water depth, 50 km (31 mi) southeast of the company’s East Hub FPSO Armada Olombendo, encountered 23 m (75 ft) net oil pay (33° API) in Upper Miocene sandstones with good petrophysical properties.
Meanwhile, Eni estimates the potential in-place resources in the range of 230-300 MMbbl of light oil, with the well data indicating a production capacity above 5,000 b/d.
The find opens new opportunities for oil exploration in the southern part of block 15/06, which was thought to be mainly gas prone.
The company and partners Sonangol P&P and SSI Fifteen will work to appraise the updip of the discovery and start studies for a fasttrack development.
In block 15/06 the West Hub and East Hub projects are currently producing around 150,000 b/d.
Later this year, Eni expects to begin Upper Miocene production in the East Hub, and the subsea boosting system for the Mpungi field, while the Vandumbu field, connected to the West Hub, will start production at the end of the year, ahead of plan. These will add a further 30,000 b/d to overall production from the block.
