Two test wells drilled by the ConocoPhillips group, one of which in Angola, have been abandoned due to lack of oil of commercial value, according to a group statement issued Wednesday in Houston, United States.
The Omosi-1 well in deep waters in block 37 of the Kwanza basin was drilled to a depth of 20,666 feet (6,298 metres) and found only a natural gas column of 525 feet.
The well has been sealed and abandoned, the group said.
The second well was drilled in the deep waters of the Gulf of Mexico at a depth of 19,400 feet (5,913 metres) and once again no oil was found and the well was therefore sealed.
Drilling the two wells cost ConocoPhillips about US$142 million. (macauhub/AO)
