PESGB London Group meeting on 9 October, 2007 will have for its London Evening Lecture: 'Doctor, does my reservoir suffer from stress?' by Jorg Herwanger.

Jörg Herwanger is a Principal Geophysicist in WesternGeco’s Research and Engineering Group in Gatwick, UK, developing workflows to build and calibrate 3D Earth models by integrating seismic inversion methods, rock physics, reservoir flow and geomechanical models. He joined WesternGeco in 2003.

His current work combines experimental observations and the development of mathematical models and workflows in time-lapse seismic, rock physics and reservoir geomechanics. Previously Jörg’s interest was in the development and computer implementation of tomographic methods to determine anisotropic electrical properties from observed crosswell data. He combined these newly developed techniques with anisotropic velocity tomography to detect and evaluate fractures.

The objective of the Society is to promote, for the public benefit, education in the scientific and technical aspects of petroleum exploration. This is achieved by a variety of means:

• Monthly lectures held both in London and Aberdeen
• Conferences & Seminars held throughout the year which cover topical issues within the industry.
• Field Trips - The first field trip was in 1965 and investigated the prospects of the English Channel. This was the first of over 100 field trips ran by the Society ranging from local evening excursions to full international field courses covering several days.
• Monthly Newsletter which contains all the up to date Society information as well as topical articles. The Newsletter is only available to members.
• Regional branches - The first regional branch was established in Aberdeen in 1985 and over the following years the Society has introduced other regional branches in the North West of England, London, Surrey and Ireland. These groups hold regular local lecture meetings and other educational activities. The largest of the regional branches is Aberdeen which has its own President and President Elect.
• Special Interest Groups - These are groups of members who share a particular interest. These also arrange meetings and other educational activities.
• External Relations - The PESGB has links with other societies and charities in the same field. The PESGB is formally affiliated to the AAPG, SEG and EAGE and has a Memorandum of Understanding with the SPE, LPS, London Geological Society, EAGE, SEAPEX and AFES. The Society also holds various joint activities with other Societies and organisations.

Andrea Collins, our Director for Hydrocarbons, will be attending this lecture at Burlington House on October 9th and looks forward to meeting you there.
