Seismic work slated for southeast Niger

Savannah Petroleum PLC has signed with BGP Niger SARL to acquire 800 line-km of 2D seismic data over part of the company’s R3 license area in southeast Niger. The company’s R1/R2 and R3/R4 permits are in the Agadem Rift basin, which contains 975 million bbl of 2P reserves with current production of 20,000 b/d, Savannah reported.

The seismic work is part of a call-off order through an unnamed Savannah subsidiary. The data acquisition will provide enhanced definition over 12 existing exploration targets identified on the operator’s existing 2D dataset. The targets incorporate stacked traps at multiple play levels including the Oligocene Upper Sokor, Eocene Sokor Alternances, and Upper Cretaceous Yogou formations.

The company is considering single exploration wells on some of these targets but provided no specific timeline for appraisal activity. In addition, seismic crews and equipment are expected “to commence shortly,” the company said.

A presentation released by Savannah cites typical discoveries are 30° API gravity oil, and reservoirs in the Agadem area are normally pressured with porosity levels in the low-20% range. Average well costs are about $4 million.

China National Petroleum Corp. established Niger’s first hydrocarbon production in late 2011, with start of oil deliveries from Sokor and Goumeri fields. The country awarded nine production-sharing agreement to five exploration companies the following year (OGJ Online, Aug. 2, 2012).
