The magmatic stratigraphy of the Sudbury Igneous Complex (Canada) is thought to have resulted from closed-system differentiation an initially homogeneous impact melt sheet. topography its upward-growing chamber floor therefore been planar and subhorizontal. However, we report on discovery a large pothole-like depression (~300 m in depth ~550 width) this complex. has revealed through two-dimensi...

Abstract We investigated the source rock potential, sequence stratigraphy, and characterized hydrocarbon reservoirs at Otumara field, Niger delta, using integrated 3D seismic, wireline log analysis, basin modeling. The burial history thermal maturity were modeled, delineated, petrophysical parameters also estimated from logs. Passey “ΔLog R ” method for estimating preliminary evaluations of tot...
