DIAGENESIS RESERVOIR BATUAN KARBONAT DI LAPANGAN SKW CEKUNGAN JAWA TIMUR UTARA

Skw oil field is located in Bojonegoro Kota District, Bojonegoro Area, approximately 135 km western of Surabaya City, Jawa Timur Province. Since 2004 the field started produce oil until now with high rate of production which come from carbonate rocks reservoir equivalen Tuban Formation. This c...

description Skw oil field is located in Bojonegoro Kota District, Bojonegoro Area, approximately 135 km western of Surabaya City, Jawa Timur Province. Since 2004 the field started produce oil until now with high rate of production which come from carbonate rocks reservoir equivalen Tuban Formation.
