Thomas is chief geophysicist of Amisia GeoConsultants. He studied geophysics at Karlsruhe University in Germany, where he also made his doctoral thesis (Ph.D.). From 1987-1997, Thomas worked in academia, mainly on reflection seismic inversion and migration algorithms. Since 1997, he works in the oil and gas industry at various companies. His field of expertise is seismic reservoir characterization (SRC) or Quantitative Interpretation (QI). At Amisia GeoConsultants, Thomas is responsible for all geophysical SRC projects and topics.
We can use all commercial plugins of dGB and third parties, offered in the software portfolio of OpendTect Pro. Collaborative project proposals in dGB style and format will be submitted. A significant part of the work will be carried out at Enschede under supervision of dGB’s experts. This ensures that the high quality standards of dGB will be met.
In order to run your projects, we have installed a powerful hardware, so that we can tackle also mid-size 3D seismic surveys for pre-stack inversion and AVO analysis.
Project archiving is very important. We make sure that we run continuous back-ups and hold archives at two distinct locations.
On the software side, our philosophy is to choose the software which is best suited for each individual project.
Amisia-GeoConsultants are based in the small beautiful town of Lingen, in the Emsland region of Northwest Germany, close to the Dutch-German border. The Emsland and the Grafschaft Bentheim to its west straddles the western part of the prolific Lower Saxony oil and gas basin. For a long time, the oil field Rühlermoor was the largest onshore German oilfield (see picture of oil field at peat production area). This field and many other small-scale oil and gas fields are still producing until now.
Our name Amisia refers to the Latin name of the river Ems, which is meandering through a lovely landscape. About 2000 years ago, from 12 BC until 16 AD, the Romans under emperor Augustus tried to conquer the western area of Germania Magna, one part of which is the Emsland. Some sources say that the famous Roman commander Germanicus came up the river Amisia (Ems) together with his soldiers in summer 15 AD, starting from a military base at the mouth of the Amisia, at the North Sea, near the modern town of Emden. All this happened after the campaign of commander Varus suffered a disastrous defeat at the battle of Teutoburg in 9 AD. The Romans never succeeded to conquer this free part of Germania and make it a part of the huge Roman Empire.
