The study of the accumulation of hydrocarbons in VLE 196, Block V, Lamar field, Lake Maracaibo, Venezuela
Abstract
The Lake Maracaibo basin is a prolific basin. Its study is not straightforward due to complex tectonic history. At this time, most of the reservoirs have been found and our aim is to better understand the reservoirs and their characteristics to better anticipate production behavior and to explore new areas that are more complex. Five reflectors were picked: the overlying unconformity, C4 reservoir layer, C5 reservoir layer, the Guasare Formation and the La Luna Formation (the source rock). Faults were picked according to the non-continuity of the seismic reflectors. The fault network is complex and consists of normal, reverse and strike-slip faults. Mapping these reflectors better defined the area of production. The main trap is a positive flower structure situated in the central area of the field. Associated faults create numerous compartments that trap hydrocarbon flow. My interpretation suggests that area west of the main fault could be interesting. This needs confirmation by a more-detailed study and more well control. Wells are mainly concentrated in the area of production; there was no well data available for the western part.
