Specialized lines on the loglog plot, already in Saphir NL, are now also available in Topaze NL. In Topaze NL new specialized plots have been added, including the square root and power law loss ratio plots for unconventional formations. Finally, unconsolidation has been extended from Saphir NL and Topaze NL to Rubis. Direct import from Geomodelers now include net-to-gross ratio, and the volume averaging interpolation method has been modified to improve the property mapping between the imported grid and the Rubis cells. It is no longer necessary to create a different initial state in Saphir NL. In Rubis the extraction of a sector for pressure transient analysis now sends to Saphir NL the exact dynamic state of the simulation at the time of the extraction. Deconvolution is enhanced by adding a material balance correction (Levitan et al.). Perrine’s method has been improved to handle multiphase analyses (Kamal et al.). Slug / pulse test analysis has been added, allowing the initial DST slugs to be analysed. This includes G-function, square root plot and the After Closure Analysis (ACA) plot. Minifrac analysis has been added in Saphir NL. In the multilayer models, vertical crossflow can now be modeled with a leakage factor or a thin interface layer. On the analytical side, Saphir NL and Topaze NL now integrate a comprehensive internal model for multiple fracture horizontal wells, including enhanced features such as a global fracture angle and composite zones. For unconsolidated formations there is individual control of matrix and fracture pressure dependence. Fractured horizontal wells now include limited entry fractures.

The gridding is not only adjusted to the flow geometry, but also to the reservoir diffusivity, providing superfine grids for extremely low permeability. Intermediate 3D local grid refinement has been created to account for vertical flow in Topaze NL without the detail of the transient analysis grid.

Substantial work was done on the numerical model, especially for the modeling of unconventional resources.

Two new additional modules, as yet non-commercial, for thermal modeling and surface networks have been included for evaluation.Ī full technical description with a list of all new features is available for download from.

Other improvements include slug test and minifrac analysis in Saphir NL, additional analysis tools in Topaze NL, an improved Rubis sector to PTA where the dynamic state of the simulation is transferred to Saphir NL and a prediction of future IPR’s in Amethyste that is now a free add-on to other Ecrin modules. One of the main areas of development has been unconventional resources, in particular shale gas, with additional diagnostic tools in Topaze NL, specifically adapted internal analytical models in Saphir NL and Topaze NL, and substantially enhanced numerical models in Saphir NL, Topaze NL and Rubis. There are substantial enhancements to all Ecrin modules in v4.20.
