Lundin Petroleum AB completes the testing of exploration well Tengis-1, located in the Blora Licence onshore Central Java in Indonesia.

The well was drilled to a total depth of 2,500m to test the hydrocarbon potential of the Oligocene CD-sandstone. While drilling, hydrocarbon shows were encountered at multiple levels and the CD-sandstone was successfully reached. A detailed log acquisition and interpretation was completed and two potential hydrocarbon zones, including the main CD-sandstone target, were identified for testing operations.

The first test was over the CD-sandstone interval which failed to recover hydrocarbons due to the low permeability of the reservoir. A second test in the Oligocene "Kranji" reservoir flowed gas to surface with high CO2 content. Following the test results the Tengis-1 well was plugged and abandoned.

The partners in the Blora Licence are Lundin Petroleum, operator, with 43.30 percent, Kufpec (Kuwait Foreign Petroleum Exploration Company) with 40 percent and CNOOC (Chinese National Offshore Oil Company) with 16.70 percent.
