The interaction between HF (hydrofractures) and NF (natural fractures) is a complex-coupled process which involves several physical parameters. Despite numerous previous works, the respective role of in situ stress, natural fracture properties, and orientations is still difficult to assess. In this chapter, a fully hydromechanical coupled numerical model has been used to simulate different three-dimensional configurations. These configurations provide insight into how a natural fracture is mecha...

Most of oil reservoirs operated by Total in West African deep offshore are multi layered highly unconsolidated sands. Burial depths, below the mud line, ranges from 500 to 2500mTVD. Sea water injection is done for pressure maintenance in deviated and horizontal wells equipped with sand control. Polymers injection for EOR and PWRI are also practiced. In theory, the very high permeability of soft sand reservoirs should allow injecting in matrix mode at high rates with small differential pressure. ...
