British oil and gas company Savannah Petroleum has made an oil discovery at the Bushiya-1 exploration well located in the Agadem Rift Basin (ARB) in Niger.

The well is situated on the R3 portion of the R3/R4 PSC Area.

Based on preliminary results, Savannah noted that the well has encountered an estimated 10m of net oil-bearing reservoir sandstones across two intervals in the primary Eocene Sokor Alternances objective. The wireline logs identified that both sections contain reservoir properties that are said to be of excellent quality.

“I am highly encouraged that the well provides further validation for our original thesis for entering the ARB.”

Drilled to a total measured depth of 2,200m, the well took 16 days to reach target depth.

The company is currently engaged in suspending Bushiya-1 for re-entry at a later date.

Savannah Petroleum chairman Steve Jenkins said: “The discovery of light oil at Bushiya-1 is a significant milestone for Savannah and our Niger project.

“As a geologist, I am highly encouraged that the well provides further validation for our original thesis for entering the ARB, being that significant portions of Savannah’s acreage have similar geology to that of the neighbouring Agadem PSC area, which has proven so prolific for the joint venture (JV) partnership led by China National Petroleum.

“I believe the well has demonstrated all of the necessary ingredients for repeatable exploration success to exist in the R3 Area and look forward with encouragement to the remaining wells in our initial campaign, being Amdigh-1 and Kunama-1.”

The company is planning to undertake production testing on the well once the results of the other two exploration wells in the current drilling campaign are available.

The rig will be mobilised to the Amdigh well site to spud the Amdigh-1 exploration well.
