Structural analysis in eastern Yemen using remote sensing data ///

Described here is the exploration technology applied in the Masilah basin of Yemen to better understand the subsurface geology. The discussion includes an introduction and project background; it then describes the structural mapping technique using remote sensing data. Illustrations describe results of the subsurface and surface structural study. The “barren” surface terrain of the area was extensively mapped with satellite images and showed strong correlation with subsurface geologic features. Landsat images and a digital elevation model covering central and southern portions of the Masilah basin in the Republic of Yemen have been used to map surface geology and structure. Mesozoic and Cenozoic extensional features were mapped in the Hadhramaut Group from the satellite data and extrapolated to analogous subsurface structures identified on a 2D seismic grid. The structure of the outcropping Umm Er Radhuma formation was interpreted by picking control points on the base of the widespread Eocene Jeza formation.
