As stated in our previous posts, the problems associated with recovery of unconventional resources like heavy/extra heavy oil, tar sands, etc. include: high viscosity, lack of communication between injection and production wells and insufficient overburden, as these conventional resources typically occur in shallow formations which cannot contain superimposed injection pressures without fracturing.
The solutions to these problems involve a combination of methods:
- To solve the viscosity issue - viscosity reduction techniques like steam injection, in-situ combustion or electrical heating can be deployed.
- To make communication between injection and production wells:
- Conventional fracturing or Fracture Assisted Steamflood Technology (FAST) can be used.
- Steam stimulation of the individual wells, until the surrounding formation is sufficiently heated to permit continuous steam injection can also be used.
- To overcome the problem of insufficient overburden:
- Well spacing can be reduced.
- Directional drilling technology can also be deployed.
