DNO has declared force majeure in Yemen, the Norwegian company said on Tuesday.
“DNO has temporarily suspended production from block 32 and block 43,” it said in a statement.
DNO said local trade unions “initiated unilateral actions that have led to work stoppages” at the blocks on Saturday.
Since last year, operations had been limited due to “local groups restricting movement and equipment, supplies and contractors”.
Production from blocks 32 and 43 averaged 1,600 bpd.
DNO has been active in Yemen since 1998, and is committed to resuming operations, according to a DNO spokesman.
