The anticipated production flow rates and economics of the well determine tubing size, which then de-termines the necessary size of each previous hole and tubu-lar. Once the tubular size and setting depths are determined, the wall thickness and grade of material are then chosen by the well designer to ensure the strength is adequate for the expected loads. Material grade is also selected to ensure it is appropriate for the fluids the tubular will encounter; cor-rosion resistant alloys (CRA) may be required in some envi-ronments such as CO2 or H2S.
