The tender from state-run Maysan Oil Company, along with the China National Petroleum Company (CNPC), French oil major Total, and Malaysian state firm Petronas, closes on Nov. 28, and the offer must remain valid for 90 days after the bid closing date.
"First drilling is supposed to start in November 2010, and three more drilling rigs are to be mobilized in the near future," the tender documents obtained by Reuters on Tuesday said.
"Therefore, two 750 HP workover rigs are required for well completion, well testing, acidizing and other workover operations in Halfaya oilfield," it added.
The contract duration will be for one year and may be extended for another year.
