Time-lapse seismic surveys or 4D seismic offers snapshots of a producing hydrocarbon reservoir and its surroundings and is the most common seismic surveillance technique in the oil and gas industry. New developments of this technology includes permanent seismic installations; observations of changes outside the reservoirs and a link to geomechanics and the use of passive recordings. In this book we are using examples from the Valhall field to illustrate examples of seismic surveillance that will include data examples from marine towed 4D, frequent surveying using permanently installed sensors, in-well recordings and analysis of passive data, including micro seismicity. Some of the historical 4D examples, an update on the state of use of permanent recordings systems are also discussed.

About Author

Olav Inge Barkved received his MSc in Oil and Gas exploration from the Norwegian Institute of Technology in 1983, and started as a Research Scientist with Geco. He worked on a variety of aspects related to seis mic reservoir characterization, interpretation technology and processing, primarily based in Norway, but including short stay at Schlumberger Doll Research and at Schlumberger Cambridge Research. In 1992 Olav joined Amoco, and remained through the merger with BP in 1998. His current role is Advisor in Geophysics, located in Stavanger, Norway. He has been supporting the development of the Valhall fi eld as a geophysicist, technology coordinator and team lead. From 2003 to 2008 Olav was the project leader of the Valhall Life of Field Seismic delivery program. In 2006 he received the Norwegian Geophysical Award for his technical contributions in support of fi eld development. BP’s Valhall Life of Field Seismic Project has been recognized by the industry by receiving the Norwegian Petroleum Directorates Improved Recovery award, the ONS innovation award and OTC’s Dis tinguished Achievement Award.

Olav has also, together with his colleagues, received the EAGE best paper award in 1997 and in 2009, the Louis Canard Award in 2008 and TLE best paper award in 2008. Olav is a member of NGF, NPF, EAGE and SEG and served as an EAGE Distinguished Lecturer in 2010. The EAGE’s Education Tour (EET) offers a one-day course delivered by renowned geoscientists at various locations globally. Accompanied by a comprehensive course book, it provides members and others access to the latest developments in key topics in the Geosciences. The Tour has been a great success since its launch in 2006.
