This study conducted within southern parts of Rufiji Trough include Lukuliro area which has been potential target for oil and gas exploration since 1980’s years. Within Rufiji trough, the discovery of Wingayongo seeps (onshore) and SongoSongo gas (offshore) attract attention on exploration activities within Rufiji trough. The previous works conducted within Lukuliro area failed to establish traps which are well demonstrated in this study. The structural and sequence stratigraphy framework were established through interpretation of six old 2D seismic data and well data from Lukuliro 1 well by using Petrel version 2013. During this investigation interesting structural features that were revealed to occur within Lukuliro area were including faults such as Listric faults, tilted growth faults, wrench faults and flower structures and small-scale folded structures (anticline). The major faults within Lukuliro area revealed to be oriented in NNE-SSW, NNW-SSE and E-W directions. These faults interpreted from different seismic sections within the study area revealed to form good structural traps. The interesting structural traps suggested to be developed within tilted faulted bocks adjacent to wrench faults and also within flower structures. Structural trap configuration revealed to be constrained by Mtumbei limestone reservoir which became sealed by shale, mudstone, and claystone and siltstone lower Kipatimu formation. However, the structural traps seem to be dominant within Lukuliro area but also the potential stratigraphic features revealed from well log interpretation and sequence stratigraphy interpretation including channel infill, unconformities, toplap and clinoforms are responsible for occurrence and accumulation of hydrocarbons. |
