Multiple gas-bearing sands were encountered at virgin pressures at depths between 6,017ft and 8,330ft, which can be correlated to those found and tested in the nearby well La-103. Well La-103 flowed at rates from 5 to 12 million cubic feet of gas per day from individual sands when drilled in 1956.
The data obtained whilst drilling showed in excess of 300ft of gross pay and also indicated the presence of over-pressured shale gas in a significant interval. After logging, a 7-inch liner will be run to isolate the sands for future testing and production.
Kevin Foo, chairman of VOG, said: “We are pleased that Well LA-105 has now reached total depth and encountered over 300ft of gross pay. Notably, the presence of gas in the shale could add upside to previous management interpretations. We will provide further detailed information to the market once the well logs have been completed.”
VOG’s principal assets are the Logbaba project in Cameroon and the West Medvezhye gas field in Siberia, Russia. Logbaba field was discovered in the 1950s and all four exploration wells encountered gas. West Medvezhye is situated in the prolific Yamal-Nenetsk hydrocarbon region in Siberia.
