The first well to be drilled off the Gambia in more than 40 years has come up dry, according to operator Far Ltd.

Far drilled the Samo-1 well to a total depth of 3240 metres and wireline logs interpreted so far indicate the main target horizons are water bearing.

However, it added that oil shows were encountered over several levels, indicating the area has access to an active hydrocarbon charge system.

The well also encountered excellent reservoir and seal facies, which Far said indicated all the key components for a successful trap were present.
