QEMSCAN Project proposal
The overall goal of this project is to establish a comprehensive multi-well data base to characterize the basin fill geohistory, tectonic evolution, and drilling record for the exploration wells of the Norwegian Barents Sea. The data base will apply recently developed state-of-theart rock analysis methods realized in the FEI QS wellsite system (FEI corp. com.; Haberlah et al., 2011a,b).
An initial 12 months demonstration period will focus on key wells penetrating down to the
Permo-Carboniferous sequences (Table 1), which contain the emerging oil plays in recent Barents Sea discovery wells, including the Gohta and Alta wells. This initial list of wells can be modified upon sponsor and participants interest. The samples will consist of well cuttings and selected core intervals granted by the Norwegian Petroleum Directorate to the consortium for this purpose, and from participant operated wells. The study will evaluate the potential to obtain valuable information form cuttings and calibrate it with the cores available. A pre-study was done together with Maersk Oil Norway AS at the Maersk Oil Research and Technology Center in Qatar, with good results based on c. 200 core samples. Previous reports show that conventional computer-processed interpretation (CPI) log calculations are highly uncertain for the mixed carbonate and clastic rocks of the Permo-Carboniferous sequences, particularly in the reservoir intervals. In addition, petrophysical studies also reveal that the heavy-mineral content highly affects the Gamma Ray (GR) and other log responses resulting in incorrect lithological and petrophysical property interpretations (e.g., Lower Cretaceous; Rodriguez, 2015). Incorporation of QS results can significantly improve the accuracy and reliability of the lithology, porosity, net/gross, and fluid saturation on these and other intervals, both within the cored and the un-cored sections (Nadeau et al., 2015a,b). This application alone can justify industrial participation in the consortium.
The main geoscience questions to be addressed are:
1. Sediment provenance and tectono-stratigraphy of the basin-fill sequences
2. Carbonate facies development and diagenesis along the platform margins
3. Petroleum-system elements in terms of source rocks, reservoirs and seals
4. Impact of uplift and erosion on petroleum migration and trap preservation
