Introduction

This section will describe the steps involved in setting up and running a simulation in Waiwera.

Description: Trials

1. Problem1

Assume a 5 km by 5 km field having a 1 km deep reservoir initially at 150 deg C and 50 bar. The distance between production and injection well is 3 km. Both are located in the middle of the reservoir and 1 km away from the reservoir boundaries. The rock properties of the reservoir are as follows: porosity = 20 %, permeability = 1.2 mD, rock density = 2600 kg/m3, specific heat of the rock = 1000 J/kgK. The fluid is produced at 100 kg/s and reinjected back into the reservoir.

2. Lumped parameter model theory book

Assume a reservoir of volume 1 m3 initially at 10 bar pressure produced at a constant rate 0.0041667 kg/s. Take properties of water at ambient temperature. The rock density is 2650 kg/m3.

3. one_cell_1e7_vol

Assume a reservoir of volume 1e7 m3 initially at 50 bar pressure and 140 deg C temperature produced at a constant rate 5 kg/s.

4. 0.1_co2_2500_cells_25e9_vol

A reservoir at 100 bar and 300 deg C has a production and injection well. The fluid flows and injected back at the same rate of 100 kg/s with 10% by weight CO2 in it. The reservoir geometry is similar to Problem1

5. simple MINC model

Assume a model 1500m long at 120 deg C initial temperature. At one end, injection 50 deg C at 13 kg/s and production at other end 13 kg/s.
