In this study , the structure , depositional system , and the seismic stratigraphy of the VLE 196 area , Block V in Lamar Field were interpreted using 3 -D seismic data and well logs to characterize structural and depositional settings of the Guasare -Misoa interval .
To demonstrate structural settings of the study area 3 -D seismic data were interpreted . Three main seismic reflectors , which are the Late Eocene unconformity , Guasare , and La Luna formations , were picked . The most dominant structure in the area is the VLE 400 Fault which was interpreted as a left -lateral strike -slip reverse fault due to its behaviors as a reverse fault in cross sections and as a strike -slip fault in strike sections . The VLE 400 Fault subdivides the VLE 196 area into two main structural blocks , a downthrown block in the western part and the upthrown block in the eastern part of the field where the hydrocarbons were trapped . Several en echelon normal and reverse faults were located along the both sides of the area . The main importance of these faults are that they fractured the La Luna source rock and created migration pathways through the reservoir layers of the Misoa Formation .
To interpret depositional system of the Guasare -Misoa interval , tops of the C4 and C5 intervals and associated C4 layers were picked based on well logs and lithofacies maps were prepared . The results of this part of the study show that the sandstones of the Misoa Formation are delta front and fluvial /distributary channel facies of delta system . The net sand thickness map of the C4 interval also exhibits southeast northwest contour patterns reflecting depositional axes in the area . Shaly units of the C4 interval interpreted as potential seals and are of variable thickness and extend .
Seismic stratigraphic interpretation of the area shows that the four main seismic facies are dominant which mainly represent the recent sediments , "C" sands of the Misoa Formation , underlying Colon and Mito Juan shales , and basement respectively . Some distributary eroded channel fill structures were also observed within the Misoa Formation , but they were not continuous through the area because of the intensive faulting . |
