June 27 (Reuters) - Valeura Energy Inc ( VLERF ) has

suspended production at its Wassana field, offshore Gulf of

Thailand, after a fault was discovered in one of the production

units, the Canada-based oil and gas company said on Thursday.

During scheduled underwater inspection, a crack was

discovered in one of the mobile offshore production unit which

"may potentially pose a risk to the structural integrity", the

company said.

Valuera is working with a team of internal and external

experts to define the optimal course of action.

The company holds an operated working interest in four

shallow water offshore licences in the Gulf of Thailand.
