Consequences of sand production: • Wellbore fill. • Equipment problems due to sand fill. • Sand erosion of downhole and surface equipment. • Sand accumulation on surface and Sand Disposal. • Production Loss. • Casing / Liner Collapse. Forces Aiding in Resisting Sand Production: • Intergranular frictional forces and bonding (cementing) help resist grain movement • Capillary […]
Functions of cement – Restriction of fluid movement between permeable zones – Provision of mechanical support of the casing string – Protection of casing from corrosion – Support of the well-bore walls to prevent collapse of formations The manufacture and composition of cement – Raw material from calcareous and argillaceous rocks (limestone, clay, shale […]
Types of Casing Based on the primary function of the casing string, there are five types of casing to be distinguished. Stove or Surface Casing The stovepipe is usually driven to sufficient depth (15–60 ft) to protect loose surface formation and to enable circulation of the drilling fluid. This pipe is sometimes cemented […]
How to plan for an Oil Well? Drilling optimization requires detailed engineering in all aspects of oil well planning, drilling implementation, and post-run evaluation Effective well planning optimizes the boundaries, concstraints, learning, nonproductive time, and limits and uses new technologies as well as tried and true methods. Use of decision support packages, which document the reasoning behind the decision-making, is […]
