Abstract
This paper presents the modelling of naturally fractured reservoirs using a multi-porosity multi-permeability thermal simulator. An iterative solution technique that allows connection between any pair of blocks is used.
Dual-porosity and triple-porosity systems are simulated. Results follow those of the analytical methods. Simulation of a thermal recovery scheme using a horizontal steam injector and a horizontal producer in a naturally fractured heavy oil reservoir is presented as an example.
