Short Course 6

Seismic Surveillance for Reservoir Delivery (EET 6)
Instructor: Olav Inge Barkved (BP)

Friday 8 June, 09:00 - 17:00 hrs

Course Description
Time-lapse seismic surveys or 4D seismic provides snapshots of a producing hydrocarbon reservoir and its surroundings. The benefit of the technology in monitoring fluid and pressure changes and to point out bypassed oil or un-drained compartments has been well documented over the last 10-15 years. Still the technology is undergoing rapid development. One of the recent focuses has been use of permanent seismic installation allowing for cost effective frequent surveying, and also allow for additional recordings not generally available. In addition recent case studies has helped raised the awareness of how seismic monitoring techniques can be used to understand possible production induced effects outside the reservoir, often linked to geo-mechanical changes.

In this course is to provide some context for what is driving the dynamic changes linked to producing a hydrocarbon reservoir and what we should expect to observe using seismic technologies in the varies geological setting. We will address key issues that impact the feasibility of time-lapse seismic, and discuss established methods. However, the focus will be on “new” technologies, use of permanent array, frequent seismic surveying and integration.

Example form the Valhall field will be used extensively to illustrate potential of seismic data and to articulate issues related to interpretation and integration. This will include data examples from marine tow 4D, frequent surveying using permanent installed sensors, in well recordings an analysis of passive data, including micro seismicity.

Course Objective
In the course we will aim at addressing:

What type of fields and mechanism are candidates for seismic surveillance?
Present an overview over available technologies for seismic surveillance of producing reservoir, with a primary focus on time lapse methods
Integrations across the disciplines, challenges and benefits
How do we value the seismic surveillance?
Can recent example of emerging technologies tells us what the future will bring?

About the instructor
Olav Inge Barkved graduated with a Geophysics degree from the Norwegian Institute of Technology in 1983. He spent the first part of his career with Geco, as a Research Scientist, working a variety of aspects related to seismic reservoir characterization, interpretation technology and processing.

In 1992 Olav joined Amoco, and remained through the merger with BP in 1998. His current role is an Advisor in Geophysics, located in Stavanger, Norway. He has been supporting the development of the Valhall field as a geophysicist, technology coordinator and team lead. Since 2003 Olav was the project leader of the Valhall Life of Field Seismic delivery program, and in 2006 he received the Norwegian Geophysical Award for his technical contribution and ability to identify and implement emerging technologies to support business objectives in support of field 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 Distinguished 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.

Who Should Attend?
This course should be of interest to managers, geoscientist, reservoir and petroleum engineers who aim for integrating time-lapse seismic data into next level of technical and business decisions and any one else who see the benefit of tracking changes is the subsurface as it take place.

The intention is to inspire, educate an possible entertain individuals how are about to embark on a seismic surveillance project and stimulate to new ideas to those with already some experience.

The will be a bias towards, marine seismic applications but this should not prohibit possible usage on land.

Prerequisites
Basic appreciation of geosciences and petroleum technical principles linked to producing hydrocarbon.
