Drilling Fluid and Cement Slurry Design for Naturally Fractured Reservoirs

For years, drilling engineers have been faced with the challenge of wells through naturally fractured reservoirs that are present around world. During drilling, pressure at bottomhole a well is frequently intentionally higher than formation pressure, which can result in loss mud surrounding rocks. cementing, even it during because cement slurry density mud. Therefore, if natural or induced fractures rocks not plugged be lost to them, reducing their permeability undesirable case pay zone. To prevent circulation and related consequences, necessary apply good cementing practices use adequate methods carefully selected materials for plugging zones. The aim this article give an overview preventive corrective applied zones as improvements technology avoid issues (e.g., aerated fluid, casing while managed expandable tubulars, lightweight slurries, etc.).
