Savannah Petroleum has made its fourth consecutive discovery in Niger with the drilling of the Eridal-1 exploration well. The Eridal-1 is located on the company’s R3 portion of the R3/R4 PSC Area in the Agadem Rift Basin.
Preliminary results based on the interpretation of the available data set, which includes wireline logs, fluid sampling and pressure data, indicate that the well has encountered a total estimated 13.6 meter of net oil-bearing reservoir sandstones in the E1 reservoir unit within the primary Eocene Sokor Alternances objective.
Wireline logs indicate the reservoir properties to be good quality and the available data indicates light oil consistent with Savannah’s discoveries to date, and in line with offset wells and the depth/API trend observed across the basin. Oil samples from the E1 reservoir unit have been taken and returned to surface using wireline testing equipment.
The well was drilled by the GW 215 Rig to a total measured depth of 2,542 meters, and encountered the main objective targets at, or near, their prognosed depths. The well took a total of 14 days to reach target depth, and all operations are expected to be completed within 23 days of spud. This compares with a pre-drill expectation of 22 days to reach target depth and 30 – 35 days to complete all drilling operations. No significant geological or drilling hazards were encountered.
The Eridal-1 well is currently being suspended for future re-entry. Production tests are expected to be performed on at least two of Savannah’s discovery wells as a precursor to the its plans to implement our Niger Early Production Scheme (EPS). The testing is expected to require standard production completion equipment to be installed in the wells, enabling them to be connected to the proposed EPS. This well testing program is currently being planned for later in the year and Savannah intends to provide further details in due course.
Following the successful results of the four exploration wells drilled to date on the R3 East area, Savannah has elected to exercise the second of the six individual options it has under contract with Great Wall Drilling Company Niger. The GW 215 rig will now mobilize to the Zomo-1 well site, located on the R3 portion of the R3/R4 PSC Area 12km from Eridal-1, where it will prepare to spud the Zomo-1 exploration well.
