OBJECTIVES

25+ years experience in exploration geophysics skilled in onshore and offshore 2-D and 3-D seismic interpretation. Proven oil and gas finder, generator of quality prospects offshore and onshore. Also skilled in complex structural - stratigraphic interpretation, attribute analyses and poor seismic quality data areas (the foothills and over layer high velocities formation basalt, limestone and allochton) experience with all phases of seismic data acquisition. I have experiences seismic interpretation, including joint activities with TPAO-ARCO-Western Black Sea project, TPIC-AMOCO-Egypt,TPAO-BP-Eastern Black sea, Arabian Gulf Oil Company-Libya, Zueitina oil company , Libya. Significant experience in advanced seismic attribute analysis and seismic Inversion interpretation.
