About the Agadem Rift Basin

The Agadem Rift Basin is located in South East Niger and covers an area of approximately 30,000 km2 in size located in South East Niger. In the modern era, China National Petroleum Corporation ("CNPC") has made 97 discoveries from the last 127 exploration wells with the principal discovered geological play being a relatively shallow Eocene Sokor Alternances tilted fault light oil block play. The basin has been in production since 2011 following a first phase of development of the Agadem PSC area (which is adjacent to Savannah permit areas) by a CNPC-led joint venture. Despite the high success rate seen in the ARB to date, Savannah believes the basin to have been relatively lightly explored, both in terms of overall activity levels and stratigraphic horizons which have been targeted. Further exploration activity in the basin is aided by the very large geological dataset managed by the Niger's Ministry of Energy & Petroleum which comprises c.12,000 km2 of modern 3D seismic, c.30,000 km of 2D seismic and over 250 well data suites.

About Savannah's ARB Project

Savannah's Niger project consists of two PSC areas (R1/R2 and R3/R4) which together cover an area of 13,655 km2. Across these permit areas, Savannah has mapped 126 un-drilled exploration prospects and leads.

Following an extensive period of geological data acquisition and evaluation, Savannah commenced its maiden drilling program with the spud of the Bushiya-1 well in March 2018. The initial focus of this program was the R3 East area, with all five wells drilled to date by the Company (Bushiya-1, Amdigh-1, Kunama-1, Eridal-1 and Zomo-1) having resulted in oil discoveries.
