Andy joined Amoco Canada in 1962 and over the next 30 years designed, acquired, processed and interpreted seismic data from the Grand Banks to British Columbia, from the Arctic Ocean to the Gulf Coast with special emphasis on overthrust plays. He also was involved in new ventures evaluations in Hungary and Bulgaria. Since leaving Amoco in 1992 to form Pap Geophysical Consultants Andy has been involved in acquisition design in many different plays world wide.
Through the 70's and 80's many of us received our early career training in the art of seismic acquisition and processing from Andy during his tenure with Amoco Canada's Tech Group in Calgary, Alberta Canada. Andy's patient and insightful tutelage was central to not only to our exploration efforts at the time, but also to many algorithms and routines that we have put together over the years.
Andy has most graciously allowed us to scan his early seminar notes [yes hand written notes, how cool is that!!] and put them up on FreeUSP for use by students of geophysics world wide. Some of the material related to specific acquisition systems is dated, but does provide a very nice historical perspective on industry advances in the oil patch. May you find this offering as useful and enlightening as we all have over the years.
