Abstract

L1 is one of the largest offshore gas fields currently under development. In order to optimize the related design, nodal analysis is applied (including proper consideration of the plant productivity, sensitivity to the tubing size, erosion effects, liquid carrying performance, and tubing string). As a result of such approach, it is shown that 13Cr material should be chosen as the appropriate tubing material. Moreover, 3-1/2 inches 9.3 lb/ft N80 tubing, 4-1/2 inches 12.75 lb/ft N80 tubing, 5-1/2 inches 17 lb/ft N80 tubing should be used for a gas production rate under 80 × 10⁴ m³/d, between 80 × 10⁴ m³/d and 120 × 10⁴ m³/d and above 120 × 10⁴ m³/d, respectively.
