NITEC performed many integrated studies for fluvial, clastic, carbonate, and fractured reservoirs. Studies include fields with hundreds of wells penetrating through multi-stacked reservoirs. In these studies, NITEC used its expertise to generate fully integrated reservoir characterization, incorporating processes from geophysics to petrophysics to geology and reservoir engineering. In most of these studies, NITEC created problem-specific software tools and workflows to address the unique challenges of the study and to more accurately and efficiently model the reservoirs. Specific challenges that were addressed for a few of these projects can be found in papers SPE 84413, SPE 74382, SPE 84085, SPE 90952, SPE 100489, SPE 161350, URTEC 2154623.
