MCHS is based on the Slow and Easy Stimulation process

• To improve injectivity of fluids into formations – injectivity enhancement process.
• To improve near wellbore conductivity.
• Low injection rate, multiple-rapid injection cycles, low proppant volumes/concentrations.

‘Controlled’ Stimulation process:

• Create a near-well Stimulated Rock Volume (SRV – conductivity enhanced fracture network).
• Complex fracture network around the well: development of multiple short fractures.
• Effective and controlled fracture network development within thin reservoir pay intervals.

Objective:

• Formation pre-conditioning for treatment of near wellbore damage and skin to improve productivity.
• Formation pre-conditioning to improve injectivity of fluids into formations.
• MCHS can be used for pre-conditioning of tight, low permeability formations (< 10 mD) + integration with a production technique.
• MCHS is ideal for tight sands, shaley sands conglomeratic sands, etc.
• MCHS is ideal for thin reservoir pay intervals (< 15 m thick).
• Formation pre-conditioning for thermal–EOR (CSS or SAGD).
• Optimize field development:
  • Steam volumes
  • Well spacing & patterns
  • Reduced environmental ‘foot print’
