Australia-based oil and gas company African Petroleum announced that it has found oil at the Bee Eater-l well, in multiple zones of LB – 09 blocks, offshore of Liberia.
As per the company’s pre-drill expectations, the well has encountered 48m of Narina equivalent oil, bearing Turonian sandstone out of a 135m oil interval.
The well was drilled to a total depth of 4,100m at a water depth of 1,067m, according to the company.
Bee Eater-l was designed to test the Turonian fan, located 9.5km west of the original Narina-1 oil discovery. It was also designed to target the potential of two deeper prospective zones in the Cenomanian and Albian, located under the Turonian, alongside targeting crestal pinch out edge of the Egret Cenomanian fan prospect, which extends across 60km².
African Petroleum is currently conducting further analysis, as reservoir permeabilities over the hydrocarbon bearing section of the well were lower than expected.
The company said the extension of the Turonian oil play from the Narina-1 discovery towards Bee Eater-1 is a major achievement in determining the oil-bearing part of the 300km² Turonian fan.
During exploration, the well encountered 14m of Albian oil bearing sandstone in the Darter prospect, which extends for more than 200km². The well came across oil bearing sandstone at the bottom of the crest of the structure, indicating a vast oil column of 800m above the well location.
During exploration at the crest, the well encountered thin oil bearing Cenomanian sandstone of nine metres, which did not contain any water, showing oil potential in the Egret prospect as it thickens into the basin.
African Petroleum deployed the Eirik Raude drilling rig to drill the well in January 2013, and took 48 days to drill the well, including 21 days of downtime, due to a malfunctioning blow-out preventer (BOP).
African Petroleum chief executive officer Karl Thompson said: "After a substantial 9.5km step out, the success at Bee Eater-1 indicates that the Turonian oil play discovered in Narina-I extends over a very large area."
"Finding oil so far down dip on the Darter Albian structure, confirms the significant potential of the Albian play," Thompson added.
The company holds a 100% share in blocks LB-08 and LB-09.
