Evaluating Waterflood Performance in a Cross Section using Reservoir Simulation: Part 3 - Primary depletion vs. Waterflood
Previous Parts Part 1 - Overview
Part 2 - Reservoir Simulation Model
Objective – Evaluate the benefits of waterflooding vs. primary depletion in our cross-section simulation model.
Reservoir Simulation Model Overview Here, we provide some relevant details of the simulation model that we use.
Simulation model type: cross-section (X-Z) Simulation grid: 100 x 1 x 20 grid cells Grid cell dimensions: Constant DX, constant DY, DZ varies by layer and equal to height of cross-section layers Only two phases present in the simulation model - oil and water Reservoir rock and fluid properties (PERMX, PERMY, PERMZ, PORO, Swi, …) vary by layer but are otherwise constant in each layer PERMX is the layer permeability in the X-direction and PERMY = PERMX PERMZ is the layer permeability in the Z-direction and is equal to 10% of PERMX All cells are active and each cell has a net-to-gross (NTG) ratio of 1.
