The duration spent on drilling is an essential element to be taken into account when exploring any hydrocarbon field as it is a direct reflection of the money spent. This article looks into Non-Performing Time events by discussing it from the sub-surface and surface scenarios, based on the analysis performed in 5 wells of the Volve Oilfield. ...
The simulator calculates the initial equilibrium state of the reservoir and defines the the pressure and saturations in each grid cell. For a reservoir with multi-phase fluid, the vertical pressure and saturation gradient can be determined from the contact depths, together with the capillary pressure at these depths.
This section contains the pressure and saturation dependent properties of the simulation dataset. This would generally include fluid PVT properties, rock compressibility and saturation values for the grid.
The GRID section determines the basic geometry of the simulation grid and various rock properties (porosity, absolute permeability, net-to-gross ratios) in each grid cell. From this information, the program calculates the grid block pore volumes, mid-point depths and inter-block transmissibilities.
The Volve field simulation directory has ECLIPSE and CMG simulation software input files. In this article, we'll describe the first part of the ECLIPSE simulation model (VOLVE_2016_EXPAND.DATA) which includes an overview on the simulation run specifications [RUNSPEC] They build the Volve simulation Model on 680 x 400 total cells with runs distributed on a machine with 4 parallel cores. It simulates a black oil fluids model, starting from 31 Dec 2007, using the 6 production wells and 2 injection wells.
