Canadian energy services company Calmena has said there is "continued uncertainty" as to 2013 drilling plans in the Waha field.
In its second quarter results statement, the company said:
"One of our rigs is operating under a contract that extends until the middle of the fourth quarter of 2013. The second rig is currently without a contract after being idle since February 2013 as a result of labour issues. We reached an agreement on our labour issues late in the second quarter and are working to secure a new contract for the rig."
It also logged several one-time charges totaling $2.3 million for relocating a drilling rig from Colombia to Texas, disputed customer invoices in Colombia and Libya and a labour settlement in Libya.
