Lecture Notes

Now I want to talk about where the mass and volume scaling factors came from.

As part of developing this design tool, we conducted a bunch of computer simulations using MODFLOW and RT3D.

Details of this work are presented in Chapter 2 of the Design Tool Manual.

Model simulations were generated for a range of values including

injected oil mass,

injected fluid volume,

well spacing and

injection sequence.

Variations in oil mass and fluid volume were represented by variations in the Scaling Factors.

We then calculated a volume contact efficiency for a target treatment zone between a set of injection wells.

The flow contact efficiency was calculated for water migrating through an emulsified oil barrier.

Water was considered ‘contacted' if it passes through a zone where the oil concentration is greater than 5% of the maximum oil retention.
