David Close is a Senior Geoscientist and Technical Team Lead with Apache Canada Ltd, where he works primarily on reservoir modeling and reservoir characterization utilizing geophysical and geological inputs. David received a B.Sc. (Hons.) in Geology from the University of Tasmania, Australia, where he specialized in minerals exploration and electrical geophysics. David went on to complete a D.Phil. in Marine Geology and Geophysics at the University of Oxford, UK, where he studied as a Rhodes Scholar and undertook research on passive rift margin evolution and basin development. David joined Schlumberger Mexico as a wireline engineer before transferring to various locations in the US as a field engineer, borehole geologist, and reservoir geomodeler before moving to Calgary, Canada, to join Schlumberger’s Reservoir Seismic Services group as an AVO inversion geophysicist. David has presented and published widely across a broad range of subjects including rift margin geology and geophysics, deep water sedimentology and stratigraphy, AVO inversion, and reservoir characterization of shale gas. David is a member of the SEG, CSEG, AAPG and AGU.
