    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 Pressure adds further grain-to-grain bonding. Forces Contributing to Sand Production: • Pore pressure relieves frictional forces. • Production of wetting phase reduces capillary pressure forces. What causes sand production? • Totally or weakly unconsolidated formations. • Changing stresses in the near wellbore area. • Water Production. Sand Production Mechanism Primer: – Rock shear collapse owing to in situ…

    Oil Well Planning

    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 key to shared learning and continuous improvement processes. It is critical to anticipate potential difficulties, to understand their consequences, and to be prepared with contingency plans. Post-run evaluation is required to capture learning. Many of the processes used are the same as used during the well planning phase, but are conducted using new data from the recent drilling…

    Acidizing Different Formations

    what is Acidizing Much of the worlds oil and gas comes from limestone (CaCO3) and dolomite (CaMg(CO3)2) formations, either in their relatively pure form or in the form of carbonate or siliceous sands cemented together with calcareous materials (CaCO3). Dolomites are similar to limestones with the exception that they generally react more slowly with hydrochloric acid. The primary method of stimulating wells drilled into these formations is to inject an acid treating solution. The acid dissolves part of the formation and may also dissolve other acid soluble material (mud damage, scales etc.), which is restricting or blocking the flow of oil or gas from the formation. Matrix acidizing increases the flow capacity of a producing formation when…
