Savannah reports fifth Niger oil strike

Savannah Petroleum Plc, London, will assess the R3 section of its R3/R4 production sharing contract block in south-eastern Niger with pre-stack depth migration (PSDM) of 3D seismic data after logging its fifth oil discovery in the area

Wireline logs, fluid samples, and pressure data indicate the Zomo-1 wildcat encountered 5.4 m of net oil pay in the E1 unit of the Eocene Sokor Alternances primary target.

Drilled to 2,499 metres MD, the Agadem Rift basin well encountered target formations near expected depths.

Savannah Chairman Steve Jenkins said the five discoveries “enable us to proceed towards our planned 2019 early-production system,” which the company earlier said would follow production tests of at least two of the discoveries.

Savannah said PSDM of seismic data acquired over the eastern part of the R3 area will provide “a significantly enhanced definition of the oil pay zones at the crests of each of the discoveries and significantly assist in full ‘field scale’ evaluations and associated development planning.”

The company also expects the processing to enhance 3D imaging of undrilled deeper Cretaceous Yogou and Donga targets identified in existing data.

The company noted “potentially significant structures” underlying its Amdigh, Bushiya, and Eridal discoveries.

Savannah has received an additional 400 line-kilometres of 2D seismic data in the central R3 area, which it will incorporate into its subsurface model.

It has ended the first phase of its R3/R4 exploratory program with the Zomo-1 well to await results of the geophysical work. It expects to start a new drilling phase early in 2019, focusing at first on the R3 east and central areas.
