Abstract

Horus field is located in the northern part of the Western Desert. Cretaceous age is the main production succession in the Horus field. The main objective of the work is to study the seismic pattern of the structural inversion and to detect the structural trend during the Cretaceous and Jurassic ages in Horus field and to assimilate the investigation results for the discovery of the hydrocarbon entrapments in the study area. Thirty 2D (PSTM) seismic lines with five wells are used, to describe the structural configuration and inversion in the study area. 2D seismic lines have been reviewed and the best quality lines have been accessed and worked on. The data calibration to the well tops is the first step, then mapping the main surfaces. The mapping from the 2D seismic lines revealed that the main fault trend is the NW-SE and the interpreted seismic sections display half-graben, which is effected by several faults. These faults were affected by differential inversion movements in two stages during the Late Cretaceous time. The inversion-related structures are the main hydrocarbon traps in the study area. Precise modelling for the Jurassic and Cretaceous faults is highly recommended, to reduce the uncertainty of the new hydrocarbon exploration in Horus field.
