“Sweetness” seismic attribute as indication for hydrocarbons in the Bandar Jaya Sub- Basin

Abstract

Bandar Jaya sub- basin is a part from South Sumatra Basin . The South Sumatra Basin is one of the basin sediment that has been proven as basin producer hydrocarbons . In the Bandar Jaya sub- basin , done several times drilling , however results drilling no get economical hydrocarbon _ so that the sub- basin this impressed no interesting for conducted exploration . Study this aim for see potency hydrocarbons in the Bandar Jaya Sub- basin using attribute seismic sweetness based on 2 passes 2 dimensional seismic and 3 well data . In relation with existence hydrocarbon , attribute sweetness will show score tall because presence hydrocarbon usually will increase score amplitude seismic and have score small frequency .  Use attribute sweetness in Bandar Jaya Sub- Basin shows relative value small in the area around 3 wells existing which has dry well status with a number of findings trace / trace hydrocarbons . Result of attribute sweetness also shows existence indication potency hydrocarbons in the Bandar Jaya Sub - Basin which is represented with relative value _ high at the peak structure anticline and on pattern structure in the form of pinchout .
