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’
