"The system we will establish will certainly help resolve the dispute between the Kurdish regional government and the central government," Energy Minister Taner Yildiz told reporters in Ankara.
Iraq's federal government in Baghdad and autonomous Kurdistan have long been divided over how to split energy revenue, which has paralysed development of new oil and gas projects in the region.
Energy-hungry Turkey is keen on seeing progress on the issue to satisfy its growing energy needs.
Yildiz said Ankara has suggested it can serve as an independent intermediary by having oil revenues deposited into an escrow account at a Turkish state bank.

Yildiz said he discussed the proposal with Hussein al-Shahristani, Iraq's deputy prime minister responsible for energy affairs, during a visit to South Korea last month.
The minister said so far Baghdad wasn't sure what type of system it wanted, adding that "energy should be used as an instrument for peace, not tension."
Moves by Turkey and international oil companies to expand cooperation with Kurdistan and develop projects without the agreement of Baghdad has ratcheted up tensions, however.
After a few of years of tension, including tit-for-tat accusations of stirring up sectarian violence, Ankara and Baghdad have tried to appease ties in recent months, however.
Asked about US response to the Turkish proposal for mediation, Yildiz said, "I am of the opinion that the formula we have developed will be approved."
Analysts say energy-hungry Turkey's dependence on expensive imports from Iran and Russia are pushing it to find cheaper sources, with Kurdistan an attractive option.
