Sand Control

sand control

  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 …

Oil Well Planning

oilfield

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 …

Natural Gas Industry

Natural Gas Terminology: Reservoir: Porous & permeable underground formation containing an individual bank of H.C.s confined by impermeable rock or water barriers characterized by a single natural pressure system. read also What is Natural Gas Field: Area of one or more reservoirs related to same structural feature. Pool: Contains one or more reservoirs in isolated structures. …

Well Pressure Control

oil well

    Basically all formations penetrated during drilling are porous and permeable to some degree. Fluids contained in pore spaces are under pressure that is overbalanced by the drilling fluid pressure in the well bore. The borehole pressure is equal to the hydrostatic pressure plus the friction pressure loss in the annulus. If for some …
