United Hydrocarbon spuds two oil wells onshore Chad

The Belanga North-1 exploration well was drilled to a total depth of 1,392 metres and encountered three oil-bearing sand intervals — two in the targeted Upper Cretaceous ‘YO’ sands with a combined thickness of 16.5 metres (net), and a previously untested five-metre (net) sand in a shallower horizon, the explorer said.

A 14.5-metre section of the ‘YO’ sand was perforated and flow tested. At the end of a 15-hour cleanup and flow test period with an 18 per cent pressure drawdown, the final flow rate was 680 bpd with no water, United Hydrocarbon added.

The company drilled another well — Belanga 1A — to further delineate the oil discovery at Belanga 1, originally drilled in the 1970s. The well encountered a nine-metre oil zone in the ‘YO’ sand, approximately 50 per cent thicker than the oil zone in the original discovery well. However, crude oil was produced to surface before the flow test was terminated due to a mechanical problem. United Hydrocarbon now plans to conduct a long-term flow test at a later date.

Ned Goodman, CEO of United Hydrocarbon, said, “We are very encouraged by the significant discovery results of our 2014 drilling programme in the DOC and DOD blocks in southern Chad. There is substantial additional evaluation work ahead of us to prove the ultimate value of the overall drilling programme. Extensive 3D seismic survey and development wells are needed to confirm the commercial viability of the Belanga discovery, as well as substantial drilling to prove the viability of the potential magnitude of the Lake Chad area.”
