Regional Studies

  • Conjugated Basins, Tectonics and Hydrocarbons (CBTH; cbth.uh.edu): This project is in collaboration with Dr. Paul Mann at the University of Houston, Texas as is the continuation of the regional Caribbean CBTH consortium. The main goal of the project is to compile all the available digital seismic and published data in a regional basis in the Caribbean, Gulf of Mexico and Atlantic equatorial basins, in order to create an integrated geologic synthesis of tectonosequences, depositional systems, major structures, petroleum geology, paleogeographic maps, and quantitative plate reconstructions for a better understanding of the hydrocarbon systems in the region.
  • Lower Cretaceous clastic wedges - an under-explored play in the Arctic (LoCRA; locra.ux.uis.no): The main goal is to improve the basin configuration and fill of the Lower Cretaceous basins in the high Arctic as input to prediction of coarse grained siliciclastic wedges as plays. LoCrA is a consortium managed by UiS (Pi: Alejandro Escalona) and UNIS (Snorre Olauseen) in cooperation with other universities from USA, Denmark and Russian, and the project was supported by 21 companies, the Norwegian petroleum Directorate and sevral software and data providers
  • Jurassic-Lower Cretaceous basinal studies of the Arctic region (JuLoCRA; julocra.ux.uis.no): the project expands from previous LoCRA research into the Middle-Upper Jurassic (Fuglen and Hekkingen formations) by integrating on- and offshore correaltions, sequence stratigraphy, biostratigraphy, regional mapping, geochemistry and paelogeography of teh Greater Barents Sea region in order to create a holistic understanding of the geologic framework of the Arctic and the petroleum potential.  JuLoCRa is a consortium managed by UiS (Pi: Alejandro Escalona) and UNIS (Snorre Olauseen) in cooperation with Moscow State University (MSU) and the Natural History Museum at  the University of Oslo (nhm/UiO). Currently the project is supported by five companies

Geophysics

  • The Low Frequency project (lowfreq; lowfreq.ux.uis.no): is a consortium managed by the University of Stavanger (PI: Wiktor Weibull) in collaboration with the University of Houston, University of Avignon,Centrale Mariselle, the University of Duisburg-Essen and Skagen 44 and PGS. PGS and several other companies and data providerswith ter the projects goal is to improve knowledge from the mathematical, physical, numerical, and applied points of view on how the low frequency content of industry 3D seismic reflection data can be used as a hydrocarbon indicator for exploration and production purposes. the project is currently sponsored by three companies

Rift Basins

  • Rift basins research: integrating field work and modelling, the project focuses on the interaction between tectonics and sedimentation in the evolution of rift basins. The field area is the southcentral part of the Gulf of Corinth which is used as analogue for syn- and early post-rift for reservoirs in the Norwegian continental shelf. The project is led by  Chris Townsend and Alejandro Esclaona (UiS).

  • Upper Jurassic mass flow deposits: Linking tectonic evolution to deposition on seismic and field scale: htis project is supported by Spirit-energy and investigates the Upper Jurassic depositional systems in the Norwegian Continental Shelf on both semi-regional and local (prospect) scale to reveal the interplay among tectonics, sedimentation, and sea-level fluctuation.
