Mafia Bigwa Rufiji permit (60% operator)
Drilling of the Mafia Deep ST-1 well was temporarily stopped at a depth of 5,519 m. From this level, a cork of cement of 360 m height was put and a liner 7 ' cemented.
These operations, necessary to security measures for the levels of gas discovered, will be followed by a ultimate drilling operation which will allow evaluation of the gas zone under the current cement. In the aftermath, a programme permitting testing of the various levels of gas revealed by electric logs will take place throughout several weeks.
It will be possible to make an evaluation of the resources at the end of all these operations. In addition, in August 2009, drilling will commence on a new exploration well in the Delta Rufiji. This new prospect, revealed by the seismic survey conducted in 2008 and interpreted in 2009, will be drilled at a depth of 2,000 m. The target of this prospect would possess the same potential as Mafia Deep ST-1.
