Future South Pars development may include 95/8-in. tubing

A study showed the benefits of installing 95/8-in. tubing strings in future South Pars gas wells in the Persian Gulf. With this large tubing, the study indicates, that a well could produce an optimum 350 MMscfd if the calculations included an erosion constant C of 175.These high rates imply that a project could obtain a 1 bcfd production rate with only four wells, with one well acting as a spare. With a lower erosion constant of 150, the four wells could still produce 1 bcfd.The 95/8-in. tubing also would decrease the total wells drilled and completed by a factor of 2 when compared with 7-in. by 5-in. tubing completions because the smaller tubing string would require more wells to attain ...
