A significant number of deepwater fields are being developed with subsea production systems. One of the challenges of using these systems is controlling hydrate formation during initial well startup. Current solutions to this problem are very expensive and operationally challenging. However, a new borate-cross linked gel system has been developed to prevent hydrate formation under static flow line conditions. This paper discusses the results of experiments performed to validate and compare the new fluid system to conventional borate-gel systems. This inhibited gel system exhibits fracturing-fluid performance equal or superior to that of conventional borate-gel systems. Specifically, the fluid exhibits much lower leak off than conventional systems. The formation-damage characteristics of this fluid are also superior to those of conventional borate fluids.
