A strategic action called “Depth Imaging Partnership (DIP)” has been created between TOTAL and INRIA. The creation of DIP has been possible thanks to fruitful collaborations between MAGIQUE-3D and Henri Calandra. The scientific responsible is H. Barucq and the coordination of DIP and its functioning are thus realised inside MAGIQUE-3D. The research program of DIP includes different aspects of sciences that must be considered to construct an efficient software program for producing accurate images of the subsurface. The RTM technique is obviously one objective to reach but the solution of the inverse problem is also an important issue for DIP. As far as the functioning of DIP is concerned, the different partners have to work jointly on topics that have been accepted by the scientific committee of DIP.

Depth Imaging Partnership has been first created in June 2009, for a duration of three years and Total decided to renew it for a duration of five years, with effect from January 2014. DIP activities are essentially formalised in the framework of PhD theses which are funded by Total. An engineer, also funded by Total, ensures the porting of student developments first on the research Platform DIP and next on DIVA. Students are also involved in the porting and by this way, they develop a broad range of skills going from numerical analysis to High Performance Computing.

The DIP project involved three Inria project-teams (MAGIQUE-3D, HIEPACS and NACHOS). Other INRIA project-teams should participate soon.

A first workshop was held in Pau in December 2010, following by a second one in April 2012 and a third one in June 2015. A fourth one took place in Houston in October 2016.
