CANADIAN company Primeline Energy Holdings has failed to find hydrocarbons in a well drilled offshore China, the second of two uncommercial wells drilled in 2015.

Primeline said its LS30 3 1 well, in the CNOOC-operated block 25/34, had encountered three sets of sandstone reservoirs as predicted when drilled to 2,000 metres.

But none of these had either oil or gas in them, leading Primeline to declare LS30 3 1 a dry well and plug and abandon the operation.

Located about 20 kilometres north of the LS36 1 gas field platform, the well was targeting a large channel sand prospect as part of Primeline’s two well exploration drilling program for 2015.

Primeline had spudded its first well for 2015, LS23 1, in September, discovering several gas bearing zones after reaching a total depth of 2,666 metres.

But while logging data had indicated a total cumulative net pay thickness of 14 metres, Primeline said the LS23 1 prospect was not likely to be a commercial discovery.

Primeline said it would conduct a careful post well evaluation of the results of the LS23 1 1 and LS30 3 1 wells in the coming months as it planned its next phase of exploration.
