Resumofirst assembled in Toulouse in 1999.The 2015 meeting in Biarritz was only the third such gathering, the second being in Cascais in 2007.With an 8year 'time step', it is hardly surprising that the conference series has not converged thematically or conceptually to some dull steady-state consensus.Rather, each of its iterations has provided researchers and other interested parties with a compact, lively snapshot of the state of play within the domain.The Biarritz meeting continued very much in this vein, despite difficult times for the industry.Participants were treated to a good sprinkling of papers from areas such as unconventionals, property modelling on unstructured grids, value of information and geomechanics.New insights and developments were presented in evergreen fields of research and development such as stochastic solutions for geophysical and production inverse problems, which show considerable maturity compared with 2007.One factor in this has been the increased sophistication of prior geological models through the use of methods such as latent variables and variational inference.Multiple-point geostatistics (MPS) models have been strengthened by further adapting techniques from image analysis and texture modelling.While the papers covered in this special issue are not an exhaustive sample of the conference content, they do a reasonable job of capturing the variability of the presentations.Olivier Dubrule reconnects us with a long-standing unsolved problem in geostatistics, namely which variogram models may be used for indicator variables.He shows
