BRIAN WM. SCHULTE STUDENT SPROTT SCHOOL OF BUSINESS – CARLETON UNIVERSITY CEO SCHIEFER RESERVOIR CONSULTING, BSCHULTE@SCHIEFER-RESERVOIR.COM Abstract In today’s industry, many say geophysics is not needed because: There are too many wells, so it is easy to map the subsurface. Seismic does not have the resolution to see the thin sands. Have not had a lot of success with geophysics in this play. This sentiment is further expressed when artificial intelligence (AI), predictive or prescriptive analytics, or machine learning (ML) are discussed, with many feeling geophysicists (geoscientists) will soon be replaced with AI or ML. Despite what is being said, [...]

SHUKI RONEN | SERCEL AND STANFORD UNIVERSITY | Summary This is the story of how airguns evolved into an environmentally friendly low-frequency seismic source. It started with a test performed by Veritas DGC that showed the value of low-frequency signal and the failure of conventional airguns to make it commercially viable. It was continued by a few ex-Veritas people in Dolphin Geophysical who saw the promise of a new source and tested a small prototype. Dolphin went bankrupt before it could fund the manufacturing and testing of a full-scale source. That was done by a start-up company, Low Impact Seismic [...]

Oil and gas occur in basement reservoirs in many parts of the world. The reserves range from as small as one or two million barrels of oil or gas equivalent to as much as almost two billion barrels of oil, as in Libya’s Augila-Naafora field. Exploration has been remarkably successful in the past decade, with important discoveries in China, Indonesia, the United Kingdom, Norway, Chad, and Argentina.
