Indonesia's Energy Department launched the latest geological and oil reserve survey tool, the Geomarin III which would improve the country's ability to detect oil reserves in the deep sea. Geomarine III is the third geological survey ship to support the first two ships with ability of detecting reserves in shallow waters, “while 76 percent (of the sea area) are deep seas, which could not be mapped due to limited ability of the survey equipments”. Tertiary oil and gas reserves have proven to be found in deep seas over 200 meters deep which store abundant oil and gas reserves. The ship was built by the PT PAL in Surabaya which cost around US$98 million, plus US$ 9 million for equipments. And to be operated by the Naval Geology Research and Development Center.
